3D At Home: No One’s Buying It??

Last week, the Hollywood Reporter reported (accurately) that a majority of the attendees at the 2011 Hollywood Post Alliance Technology Retreat believe that 3D in the home is ‘dead’ and will never catch on.
Yes, I know you’ve heard about and read several surveys taken in the past year that show little or no enthusiasm for 3D at home. However, when people who create and distribute movies and TV shows for a living give 3D at home the thumbs-down, that’s big news.
I’ve attended every HPA Tech Retreat since 2002 and presented at most of them. Last year, we had a 3D supersession where many attendees expressed skepticism that 3D at home was viable. This year, the number of naysayers was substantial, as evidenced by a show of hands during the Day 1 presentation recaps by HPA leaders Leon Silverman and Jerry Pierce. (This year’s Retreat had 450 registrants, by the way.)
The annual broadcasters’ panel brought forth more skepticism, with Fox saying that until there was a workable, viable ATSC 3D standard, they would stay on the sidelines. Those sentiments were pretty much echoed by ABC, NBC, Sinclair, PBS, and CBS.
As I mention in another post, we had a great breakfast roundtable discussion on 3D in the home, and whether it was a flop, partially successful, or had any real future. We also discussed the relative scarcity of 3D movies, which led to a question about why Hollywood isn’t remastering more of their older 3D movie titles into the Blu-ray format. The reply was that the cost to do those remasters probably wouldn’t be justified by Blu-ray disc sales, let alone rentals.
Let’s face it; 3D TV stumbled badly out of the gate in 2010. TV manufacturers locked up the most desirable 3D Blu-ray discs as part of exclusive TV bundles, creating an instant shortage of compelling 3D content. Want to watch Avatar in 3D? Sorry, you’ll have to buy a Panasonic 3D TV. How about any of the Shrek movies? You’ll need to buy a new Samsung 3D TV. Despicable Me? You’re looking at a new Sharp Aquos, pal.
What’s that – you just dropped $2,000 on a new 55-inch 120 Hz LED LCD TV a year ago? Hmmm – that’s a problem.
How about the new 3D TV networks? Well, ESPN 3D is a barker channel during most of the day. The World Cup was fun, but half the shots didn’t benefit at all from 3D.
Last fall, DirecTV’s 3D pay-per-view channel was showing Journey to the Center of the Earth, followed by Journey to the Center of the Earth, followed by Journey to the Center of the Earth…well, you get it.
As far as 2011 goes, the outlook for 3D TV sales isn’t very sunny. Nielsen’s annual State of All Media survey, taken in Q4 of 2010, showed that “…76% of respondents ‘probably won’t or ‘definitely won’t’ buy a 3D TV in the next 12 months. 2% of respondents already own a 3D TV, while only 6% “definitely’ or ‘probably’ will buy one.”
The problem is compounded by VIZIO and Toshiba saying that consumers don’t need to buy expensive LCD glasses to watch 3D TV. VIZIO is leading a charge to passive (half-resolution) 3D TV, with the selling point being that you can use those same 50-cent RealD circular polarized glasses they gave you at the local multiplex cinema.
According to a news story in today’s TWICE magazine, LG showcased their new line of passive 3D LCD TVs – called Cinema 3D – at the Film Independent Spirit Awards last week. The TWICE story quoted LG Electronics USA president Wayne Park as saying, “We think we can take advantage of — at least in 3DTV — the leadership position for the whole industry…with our distinguishing 3D technology, we can bring a much more affordable and enjoyable experience to the consumer, so that our 3DTVs can leap ahead of the industry.” Also, “Park said he believes passive-glasses technologies will ultimately win out over active-shutter systems due to the many benefits that resonate with consumers.”
Toshiba’s claim that you can drop glasses altogether upsets the apple cart even more, and has apparently convinced the average Joe that there is a format war in 3D (shades of the 1080i vs. 720p battles ten years ago). Skipping past the technical details, what today’s consumers are hearing is that 3D is very much in the laboratory stage and that it is probably a smart idea to sit on the sidelines for a while until all of the details are worked out – and until 3D TVs without glasses are widely available.
So, what’s a TV manufacturer to do?
First off, it’s evident that consumers will NOT pay a premium for 3D functionality. There are simply too many 2D TV models available for less than $1,000, including a couple of 55-inch screens. Asking consumers to pony up an additional $500 – $1,000 just to watch a handful of movies and 3D networks is a waste of energy right now…particularly when you consider all of the people who bought new big-screen LCD and plasma TVs in the past five years.
Second, release the exclusively-bundled 3D Blu-ray discs immediately to the open market. If you want someone to buy a fancy new sports car, make sure there are plenty of gas stations where they can fill it up!
Third, drop the prices on 3D Blu-ray players to a level commensurate with networked Blu-ray players. Those are selling very well because consumers are using them as Internet TV set-top boxes to gain access to Netflix (20 million subscribers and counting).
Fourth, continue exploring marketing partnerships with content producers to create 3D channels that more people can watch. Currently, only the Sony-Discovery-IMAX 3Net channel and ESPN’s 3D channel are available to any viewer on any Pay TV system. 3D on DirecTV does nothing for a Comcast subscriber, or a Dish Network subscriber. Comcast’s new 3D channel is inaccessible to Verizon FiOS customers. Content drives TV viewership – HDTV started in 1998 but didn’t really take off until about 2004, when all of the major TV networks finally had a strong slate of HD programming to watch.
Unfortunately, the perceived format war between active shutter, passive, and autostereo (a really inferior way to watch 3D, if you ask me) is going to keep sales of 3D TVs down in 2011. Consumer enthusiasm is so low that most of the 3D demos at my nearby Best Buy appear to have been turned off for good. (Not that they could find any working active shutter glasses if they needed to…)
At this past Sunday’s Ambler Theater Oscars Party, I set up a Samsung PN50C8000 3D plasma TV with four pairs of glasses (fresh batteries in every one) and a 3D animated movie (Monsters vs. Aliens), smack in the middle of the concessions lobby. Plenty of people (young and old) came over to watch for a few minutes, were appropriately wowed, asked what the 3D set-up cost, said “that’s nice, but I can’t see having to wear glasses to watch TV” and then walked away to one of the three main theaters.
They’re just not buying it.
CES 2011: Afterthoughts

CES is a strange show. It’s so big and has so many exhibitors that you keep thinking about what you’ve seen for weeks afterwards – kinda like mental ‘aftershocks’ and flashbacks. And I’ve had a few of those since returning home almost a week ago.
Here, in no particular order, are some afterthoughts from CES:
Gesture Recognition – Hey, Where’d it Go? In 2007, 2008, and 2009, gesture recognition for TV operation was a BIG deal at CES. Hitachi, Toshiba, JVC, and others all showed sophisticated gesture-recognition systems at previous CES shows, and last year’s Toshiba exhibit managed to combine GR, their Cell processor, and 3D in a most impressive demonstration.
This year? Hardly any GR demos at all, aside from some rather crude examples found in the Hisense and TCL booths that barely worked. The TCL demo was so insensitive that visitors to that particular exhibit looked like they were swatting at flies, while the Hisense demo consisted of someone doing a work-out while following an animated trainer on a nearby LCD TV.
OLEDs – We’re Still Waiting: Every year, Samsung, Sony, LG, and others tease us with demonstrations of gorgeous-looking OLED TVs in a variety of screen sizes. Yet, we continue to wait, and wait, and wait for production models to come to brick-and-mortar stores. (The XEL-1 doesn’t count.) Sony even built an autostereo screen into a 24.5-inch AM OLED display, while Samsung’s 19-inch AM OLED was 50% transparent.
We’d all like to replace our LCD and plasma TVs with OLEDs, but it looks like we’re going to be drooling and waiting a LONG time before that happens. Smart phones have already beaten us to the punch and it looks like tablet computers will be the next place to roll out (literally) OLED screens.
And yet, every year, we get our hopes up again…
Picoprojectors: Vaporware? After reading a recent Display Daily post by colleague Matt Brennesholtz at Insight Media, I fired off an email to eight different IM analysts, asking them if they had ever seen a picoprojector in use in 2010 other than at a trade show or a display technology conference.
This may surprise you, but each one of them responded with a simple, “No.” None of them had spotted any at retail, either. And yet, companies like Pacific Media Associates continue to issue optimistic sales forecasts for picoprojectors, while Texas Instruments had a full suite of “picos” at CES that were built into smart phones, a tablet computer, cameras, and pocket projectors.
I think tablet computers may derail picoprojectors, or obsolete them completely. How about you?
Hey Sharp, 3D was SO 2010! Sharp once again had an enormous CES booth filled with big, colorful LCD TVs (70-inches was the big news this year) and finally had a few 3D Blu-ray demos to go with them. Well, a year late isn’t too bad, I guess. The only problem is; Sharp’s share of the U.S. TV market has been steadily dropping since 2005 and is below 3%, according to NPD Display Search’s 3rd quarter 2010 numbers. That’s embarrassing! Even Panasonic now ships more LCD TVs than Sharp, who pioneered the LCD TV biz a couple of decades ago.
The four-color Quattron technology, while intriguing, doesn’t appear to have caught on with consumers so far, and we all know how disappointing sales of active shutter 3D TVs have been to date. To add to Sharp’s problems, Sony has not fully committed to fund its share of Sharp’s new Gen 10 LCD plant. Sony was originally on the hook for a 34% stake, but according to multiple reports may cap that investment at 12% and look to China for a cheaper source of LCD panels.
This would be a good time for a comeback, kid…
Mitsubishi Thumbs its Nose at the Experts: Yep, those ‘diamond’ guys are still making rear-projection DLP TVs, and apparently selling plenty of them, too. Their 92-inch roll-out at CES drew big crowds and will probably ticket around $5,000, which is less money than a decent front projector, screen, and home theater in a box will cost you. Did I say it could do 3D, too? Side-by-side, top+bottom, frame packing, checkerboard – you name it.
We “experts” predicted Mits would fall by the wayside as the LCD and plasma juggernauts rolled through the market. Uh, not quite. And with Mits’ new laser light engine, the issue of lamp replacement will eventually fade into the sunset. Texas Instruments is thrilled that they still have a RPTV customer, and as long as Mits can manage its bill of materials (BOM) costs, they can remain in the catbird seat for a few more years until something better comes along.
(Sound of a big raspberry coming from Irvine…)
DisplayPort: On Your Mark…Get Set…Get Set…Get Set: Is DisplayPort ever going to take off? I saw several cool demos of multi-monitor support and embedded 3D notebooks through DisplayPort in the IDT suite, along with a basic booth in the lower South Hall showing wireless DisplayPort over WHDI and a multi-channel audio concept demo. But who’s using it, aside from Apple?
In the meantime, HDMI (Silicon Image) showed ViaPort (multiple connections to a TV hub and one to a AVR with automatic streaming for the highest-supported audio format), MHL (Mobile content through a mini HDMI interface to TVs and other devices), and ViaPort for digital signage (Blu-ray at full resolution to eight daisy-chained TVs through single HDMI connections).
Maybe they misplaced the starter’s gun.
VIZIO – The Next Apple? Not only has VIZIO staked a big claim in the TV marketplace, they also rolled out a tablet computer and a smart phone at CES. The VIZIO Phone has a 4-inch display, GPS, WiFi, two built-in cameras, HDMI output (MHL), 2 GB of storage and doubles as a universal remote for VIZIO products.
The VIZIO tablet is pretty impressive, too. It also has WiFi, GPS, and a high-rez camera for videoconferencing, HMDI output, three internal speakers, and 2Gb of internal storage plus a MicroSD card slot. And yes, it can also work as a universal remote. The guys at VIZIO also thumbed their noses at all of the active-shutter 3DTV manufacturers and opted to go with passive 3D in a 65-inch LCD set that uses inexpensive RealD (circular polarization) glasses.
What’s next, Mr. Wang? Brick-and-mortar ‘VIZIO Zone’ stores in selected cities and malls? (Don’t laugh, he might just try it!)
Active Shutter 3D – Has it Peaked Already? In addition to VIZIO, LG and JVC also showed new large LCD TV products with embedded micropolarizers and inexpensive passive 3D glasses. I saw a few passive demos here and there, but these were the big three as far a product rollouts. LG even had large bins with passive glasses at the numerous entrances to their booth.
While passive 3D certainly solves the problems with fragile and expensive glasses, it can play funny tricks with screen resolution as every other horizontal row of pixels has micro-sized circular polarizers that work in opposite directions. That can make the screen appear to have noticeable black lines on it when viewing normal content, a problem that would be solved by moving to 4K native resolution (thereby adding to panel complexity and costs).
Still, passive 3D could put a crimp in 3D TV sales this year as it feeds into the average consumer’s wariness of another TV ‘format war.’
Step Right Up and Getcha 3D Camcorder! This product category went from 0 participants in 2010 to “I lost count’ in 2011. Panasonic, Sony, ViewSonic, JVC – you name the company, they had a 3D camcorder out for inspection somewhere in their booth. And it wasn’t just the big boys, either. Ever hear of Aiptek? Didn’t think so. They showed a palm-sized 3D camcorder under their name that coincidentally appeared in the nearby ViewSonic booth.
The question is how many of these cameras were using conversion lenses (Panasonic) and how many were capturing video through true 3D optical assemblies (JVC, Sony). The Aiptek model in question may also have been converting 2D on the fly, but it was hard to tell from the sketchy details in their booth. Also, Sony’s and JVC’s cameras use the full-resolution frame-packing format, similar to Blu-ray DVD.
OK, who wants a 3D camcorder? (And a 3D TV to go with it?)
Hey, Didn’t You Guys Just Lose $8.5B? Once again, the United States Postal Service occupied a healthy-sized booth in the upper South Hall. And once again, they were shilling for Priority and Overnight Mail, package shipping, and a new service called PremiumPostcard.com direct mail marketing. They also featured something called the Fast and Furious Challenge, although no racecar was in sight this year.
Ordinarily, I’d be kinda upset that taxpayer money was spent this way…except that the USPS operates as a quasi-private agency, living entirely off revenues from mail delivery. So maybe I should instead give them props for trying to drum up more business, except that it’s hard to understand how many of the surrounding Chinese manufacturers would benefit from any USPS offerings.
As long as they don’t drop Saturday delivery, I guess I don’t care…
CES 2011: Applications? Plenty! Buzz? Ahhh, Not So Much…

If you still needed any convincing that the U.S. economy is on the rebound, the 30-minute-long cab line at McCarran Airport did the trick. Attendance at this year’s running of the world’s ultimate gadget expo was WAY up, probably hitting 2007 levels. (CES claimed 140,000 in attendance, but my guess is that the real number was more like 90,000 – 100,000, based on cab lines and traffic.)
But CES was a vastly different show than in recent years. True “wowza!” product demos were few and far between. Instead, what we saw were ‘apps’ – practical, real-world applications of technologies introduced in the past couple of years. (And of course, umpteen million tablet computers.)
Smart phones were huge this year, and they were doing everything from shooting videos to doubling as game controllers and even talking to ovens and refrigerators. The Android OS rules this space, with Windows coming up far behind. If there was a possible use for a smart phone, someone demonstrated it in a booth (including 3D).
Discussions of “the cloud” were heard in every hallway. For those readers who don’t know what “the cloud” is, it’s the concept of storing and accessing media files from remote servers, streaming or downloading it to view on portable and desktop displays. Netflix streaming is a good example of “the cloud,” and many industry analysts believe “cloud” delivery of content is where everything is headed – no more big hard drives or optical disc readers, just fast wireless and wired Ethernet connections.
Speaking or wireless, it’s all the rage. I lost track of all the wireless connectivity demos, ranging from wireless USB 3.0 docking stations to full-bandwidth 1080p video and multi-channel audio streaming to TVs from Blu-ray players, using the 6 GHz radio frequency band.
And those tablet computers…they were everywhere, so many that tablets suffered the ignonimous fate of moving from the most anticipated new product at the opening of the show to “so what?” products by its closing. I saw just as many off-brand and white label tablets in the lower regions of the South Hall as I did at the Blackberry, ViewSonic, Samsung, Sharp, Sony, and Panasonic booths. Can you say, “buzz kill?”
Last year’s show was dominated by 3D. You couldn’t get away from it! This year, the 3D pickings weren’t quite as abundant, although a few companies (Sony and Panasonic) continued to place a heavy emphasis on stereoscopic TV viewing in their booths.
Toshiba did too, except they chose to emphasize glasses-free (autostereo) 3D exclusively in their booth. LG opted to show passive 3D products that use inexpensive circular-polarization glasses, along with a single autostereo LCD TV. Meanwhile, Sony had concept demos of a portable 3D Blu-ray player and a 24-inch autostereo organic light-emitting diode (OLED) TV.
The reduced emphasis on 3D might have something to do with the paltry sales of active-shutter 3D TVs in 2010. Sales numbers were nowhere near what anyone predicted, which could partly be blamed on the recession. But it could also be blamed on a perception that there is a format war brewing in the world of 3D TV (shades of the 1080i vs. 720p battles from ten years ago).
Toshiba’s recent announcements of glasses-free 3D TV certainly added to that perception, and that’s all they showed at CES. Meanwhile, LG and JVC seem to be leaning towards passive 3D (embedded polarizing filters) in their LCD TVs, and in fact LG had large baskets of passive 3D glasses available to both visitors.
The LG autostereo LCD TV worked about as well as the Toshiba models. As you change your viewing position, patterned film retarders (PFRs) built-in to the LCD surface create a new perspective and viewpoint, blocking some pixels and revealing others. It works, but you’ve seen the same effect before with static digital signage displays in retail stores and in airports. And it’s not easy to watch 3D video this way for very long.
There were plenty of autostereo handheld display demos. LG’s new Optimus smart phones were shown as game controllers for 3D gaming systems, but were also displaying mobile 3D content. Nearby, LG had a demonstration of autostereo 3D as broadcast from Las Vegas DTV station KLVX, using the MH mobile digital TV standard.
Sony showed an autostereo media player in its booth, along with the aforementioned portable Blu-ray player with autostereo screen. (Frankly, I think the market for portable BD players is pretty miniscule, but the autostereo images looked quite nice.)
Sharp, who last year missed the boat on 3D – and whose U.S. market share in TV sales continues to drop precipitously – rolled out the 3D bandwagon this year, with a full line of Quattron 3D TVs out for inspection, including a new 70-inch model. Hidden away in another part of their booth were demos of 3.8” and 10.6” autostereo LCD displays for handheld devices.
JVC, who has been concentrating more on projection products lately, unveiled their first consumer passive 3D TV. It’s a 65-inch, edge-lit LED model with embedded micropolarizers that work with RealD theater glasses. Back in the Central hall, Hisense, Konka, and TCL all showed Chinese-made 3D sets with active shutter glass technology, while VIZIO threw its hat in with the passive 3D crowd, unveiling several models that use embedded polarizing filters and passive eyewear.
Hmmm…maybe there IS something to this 3D format war, after all…
It was hard to find a TV at CES that didn’t sport some sort of Internet connection. Panasonic (VieraCast), VIZIO (VIZIO Internet Apps), Sony (Google TV), LG (Smart TV), and Samsung (Samsung Apps) all had full plates of NeTVs out for inspection, along with numerous connected Blu-ray players. By the way, the ‘connected’ part of Blu-ray players is the big reason they are finally selling so well, as consumers apparently can’t get enough of YouTube and Netflix streaming.
There were also plenty of demos of smart phone control of TVs, using WiFi to stream back a lower-resolution version of the content being displayed on-screen. I’m not really sure why anyone would need that functionality, especially if they are already sitting in front of the TV watching whatever program or movie is playing out. Maybe it’s just in case you need to run to the bathroom?
LG went everyone better with their ST600 Smart TV adapter. Remember ATSC set-top boxes from the DTV transition? Well, the ST600 is an Internet TV adapter that works with any set through its HDMI port. It costs about $150, and gives you a Web browser, plus one-button access to popular Internet TV sites like Netflix, CinemaNow, VUDU, Hulu Plus, YouTube, MLB TV, Pandora, and others.
Sony prominently featured their Sony Smart TV product line, based on Google TV. This product has really stumbled out of the gate, probably because of the incredibly complex keyboard remote control (remember Web TV, anyone?) and the fact that a majority of Web video surfing can be accessed with directed one-button Hulu Plus, Netflix, and YouTube apps. Maybe we’ll see a simplified version of the product from Sony in 2011.
Panasonic rolled out its own tablet computer, as previously mentioned. The Viera Tablet is part of a “cloud” focused content delivery strategy (there it is, again!) that will let consumers access on-demand and VIERA Connect content. The tablet will actually be available in several different sizes, ranging from 4” to 10,” and also functions as a TV remote control.
Sharp also featured connected Blu-ray players, with directed apps for VUDU taking center stage. Three new models use wireless connections to access Netflix, VUDU, Pandora and YouTube content via streaming connections. They also took the wraps off a 70-inch Quattron LCD TV with built-in WiFi and a support for CinemaNow, Netflix, VUDU, and DLNA video streaming.
Samsung didn’t have quite as many sexy NeTV announcements, but they did have the largest LCD TV at the show (75 inches) and prominently featured their Smart Hub technology. You can access the usual suspects through wired and wireless Ethernet connections, along with Blockbuster, MLB.TV, AccuWeather, Facebook, Hulu Plus, and History Channel content, among others.
There wasn’t a lot of projector news from CES. Texas Instruments used the event to launch a new line of DLP Pico HD chipsets. These are tiny WXGA-resolution (1280×800 pixels) digital micromirror devices (DMDs) that are used in picoprojectors and pocket projectors, and there were plenty on display in the TI suite. They had picos running in GE digital cameras, Sharp smart phones, and even a prototype tablet computer.
Sony even showed a DLP-based picoprojector in a new digital camera at Digital Experience, an interesting development considering that both companies parted ways back in 1996 after Sony built its first and only SVGA DLP high-brightness projector.
Other picoprojectors were shown from LG, ViewSonic, Acer, and Optoma. The Optoma iPod docking station with built-in picoprojector was a clever product, as was the GE digital camera. But most of these projectors cast small, dim images, and you have to wonder how the explosion of tablet computers will affect this market, considering that both picos and tablets would be used for very small group presentations.
Several 3D projectors took a bow in Las Vegas. Mitsubishi finally has a model number for its LCoS 3D projector (HC9000), while Sharp announced the XV-Z17000 DLP 3D chassis. Samsung’s also got a new 3D box, the SP-A8000, which also uses DLP technology. Over in the JVC booth, the previously-announced DLA-X9 and DLA-X7 D-ILA (LCoS) 3D front projectors now have THX 3D certification – apparently the only models to earn that appellation so far. The general consensus is that DLP produces better blacks and higher contrast than LCoS 3D projectors, but that will remain to be seen. (I expect to have a review sample of the Mits unit in mid-March.)
Mitsubishi’s big screen TV division continues to hang on in the rear-projection DLP marketplace and is actually doing quite well, thank you very much. (It’s easy to capture 100% market share when you are the only player!) They launched a 92-inch DLP set with 3D compatibility, and while it doesn’t have a model number yet, expect it to sell in the mid-$5000 range, with active shutter glasses an extra.
WIRED VS. WIRELESS NETWORKING
I met with most of the major networking groups at CES. Two of them (HDBaseT and DiiVA) are very close in theory and practice, with structured wire being used to distribute video and audio between connected devices. Both systems also support USB connectivity for remote gaming control, and both systems can deliver power to connected devices (100 watts for HDBaseT and 24 watts for DiiVA).
Many commercial interface manufacturers are incorporating HDBaseT infrastructures into their AV switching products, the latest being Crestron (Digital Media) and Gefen. AMX already uses a version of HDBaseT in their AV switchers and distribution amplifiers.
DiiVA is apparently gaining popularity in China, where new apartment buildings and houses all have structured wire pulls. Most of the companies that have DiiVA-compatible products are also (not surprisingly) based in China.
On the wireless side, Summit Semiconductor, Aeleron, and Amimon all showed system-on-chip solutions for high-bitrate video and audio distribution. Amimon is the founder of the Wireless High Definition Interface (WHDI) and showed wireless display connectivity to remote PCs, as well as Blu-ray 1080p playback to specially-equipped LG and Hisense wireless LCD TVs.
Aeleron featured Ultra WideBand (UWB) connectivity of 1080p streaming and docking systems that work with TVs, laptops, smart phones, and other media players. They also featured DLNA-compatible UWB adapters for in-room signal distribution (UWB can’t go between rooms) and driverless HDMI interfaces.
Summit’s demo was perhaps the most interesting. It featured uncompressed distribution of wireless multi-channel surround audio to randomly-placed powered speaker columns. A special remote activates a supersonic Doppler system that automatically adjusts the levels of all speakers so that you are sitting in t ‘sweet spot,’ no matter where you are in the room, or where the speakers happen to be placed. It takes all of ½ second for this adjustment to be made.
Back over in the Hilton, Sigma Designs has found a way to reduce line noise and broad spectrum interference in HomePlug systems. Turns out, all those battery chargers and AC adapters are pretty ‘dirty,’ which clips the available bit rate for moving video and audio through decoupled AC power lines. With the Sigma enhancements, the receive speed (to a media player or TV) is as much as 65% of the transmit speed (from the playout source). With normal HomePlug appliances, the receive speed can drop to as little as 20 – 25% of the transmit speed.
There was so much more to report on from CES. Many of the new TVs and accessories will be featured in upcoming spring line shows, where I’ll take a closer look at each. You can also find news about specific model numbers and pricing at many other media outlets, along with each manufacturer’s specific Web sites.
If there was anything to take away from the show, it was that TVs were not the big news at CES this year. Instead, multi-function smart phones and connected media appliances generated all the buzz. We’re definitely in for a protracted battle between the “your TV should be the hub!” advocates and the “Connect outside the TV!” evangelists, not to mention the “go wireless!” and “use wired connections!” camps.
I tend to favor the “connect outside the TV” and “go wireless” arguments, although it is a tricky task to stream high-definition video in an uncompressed format between rooms in a house. (And no, the FCC taking away more UHF TV channels won’t help at all – there’s not enough spectrum space in the UHF band for 512 MHz channels!)
3D will continue to muddle along this year, as the economy slowly recovers and consumers sit on their hands. The confusing “glasses or no glasses” messages won’t help. Active-shutter 3D and passive 3d are clearly superior to autostereo 3D for viewing TV shows and movies, but you have to test-drive all three modes first to understand why. Look for the passive systems from LG, JVC, and VIZIO to pick up more market share as the year winds on and consumers realize they can use their freebie movie theater glasses at home.
NeTVs are here to stay and potentially a lot more popular than 3D. Sony’s Google TV approach may be too complicated for most consumers, who are likely to favor the simpler direct channel apps offered by everyone else. And if they can access Netflix, YouTube, and Hulu Plus, they may not need much else. Look for LG’s Internet converter box to be copied by other manufacturers so that older TVs can join in the fun.
It was nice to see a few OLED TV demos this year, but once again the technology just isn’t ready for prime time. Look for Samsung to show an OLED Galaxy tablet later this year, if for no other reason than to prove they can make one. But it will be a while before you can buy it. The rest of the tablet and smart phone crowd will stay with tried-and-true LCD technology for the time being.
Blu-ray disc and player prices will continue to plummet. I’ve predicted that major brands will stop making conventional DVD players altogether in 2011, moving to Blu-ray as their exclusive platform. While we didn’t see any BD players with internal hard drives like those sold in Japan, they’re not far off. Too many people are using Netflix streaming and would like to try a straight digital download for improved image quality. What better place to enable a DVR than in a BD multifunction media hub?
And get used to using your smart phone to do everything. Game console controls, TV remotes, autostereo displays, even diagnostic tools to use with connected major appliances – all of these smart phone applications were shown at CES.
So was a iPhone case with a built-in bottle opener, which might turn out to be one of the most useful smart phone “apps” of all…
Vizio VF551XVT LED LCD HDTV

As prices of flat-screen HDTVs continue to plunge, you can point the finger at one company in particular for influencing that trend: Vizio. The aggressive discounter has become a dominant player in LCD HDTV sales, capturing the #1 position on more than one occasion and sticking it to established stalwarts like Sharp, Sony, and Samsung.
First getting started with wholesale clubs like Costco and Sam’s Club, Vizio is also in Wal-Mart and Sears. Taking a page from Samsung, the company advertises extensively during the fall football season. And its lineup of TVs covers all of the bases from a $200 19” LCD model to three 55-inch 1080p LCD sets, the most expensive of which is $2,199 and the subject of this review.
Vizio’s VF551XVT will naturally get lots of attention for its super-low price. The fact that it has an LED backlight and incorporates 240Hz motion processing will only attract more attention. And yet, its narrow viewing angle impaired the viewing experience for me.
Figure 1. Vizio’s VF551XVT is the company’s first LCD TV to use an LED backlight.
OUT OF THE BOX
The VF551XVT comes ready to play, out of the box. Simply unpack it and find a suitable flat surface to set it on – the stand is attached. (Vizio also offers a white glove delivery service for a few extra dollars.)
You’ll get plenty of inputs, as is usual with Vizio. The rear panel contains four HDMI 1.3 jacks, one of which also comes with analog audio inputs for connection to older DVI-equipped DVD players and set-top boxes. There’s also a component video input, a PC input (VGA jack), and one each composite and S-video jacks with analog audio.
On the left side, you’ll find a fifth HDMI 1.3 connector, plus another component video input and a second composite video input. (Question: Why are manufacturers of large 1080p LCD HDTVs including composite video jacks at all, let alone two of them?)
Figure 2. You won’t lack for connections on this TV. How do five HDMI inputs sound?
An optical Toslink jack on the rear panel provides a digital audio hook-up to an external home theater receiver, and there are also analog stereo audio output jacks. For TV viewing, the VF551XVT includes a single F connector, which can pull in either terrestrial (ATSC) digital and analog TV stations, or analog/digital cable channels that haven’t been encrypted.
Vizio has also included an USB port for listening to and watching a wide range of portable media files, including MPEG4 (H.264 AVC), Windows Media 7/8/9, MPEG2, AAC, MP3, and JPEG still images. These external flash drive connections are actually quite popular with consumer, particularly for showing home video or digital photographs!
REMOTE AND MENUS
The supplied remote is a great design, with just the right number of buttons that are large enough to operated without reading glasses. It’s also backlit for darkened rooms. You can select banks of inputs by pressing one of four smaller buttons and then toggling through the choices.
Figure 3. The remote is stylish and well laid out.
The menus are well designed, and navigation through them is quick and easy. For the average viewer, you can select one of nine factory picture presets, all of which can be altered. The differences between the sports-themed presets (Football, Golf, Basketball, and Baseball) are almost insignificant, and you have to wonder why Vizio included so many. The good news is, you can tweak all of them to your heart’s content.
Vizio has also incorporated a host of image processing adjustments under the Advanced Video sub-menu. For more detailed calibrations, Vizio has included four color temperature presets (Normal, Custom, Cool, and Computer), plus red, green, and blue contrast and brightness adjustments.
Heads up – if you want to calibrate the TV (or have someone else do an ISF calibration), you’ll need to leave all of the image enhancements off, particularly the color enhancement, adaptive luma, and smart dimming – a feature that adjusts the brightness of the image dynamically to improve blacks by controlling blocks of LEDs.
The white LEDs – 960 of them, divided into 80 blocks – can provide instantaneous dimming to lower black levels in dark scenes while raising them in bright scenes. In theory, that should result in very high contrast ratios…except that highlights are also dimmed as black levels drop, and that makes for some screwy gamma curves.
120Hz LCD TVs are pretty commonplace now, but their effectiveness in reducing motion blur is debatable. Vizio has moved to a 240Hz system, deriving that frame rate by a combination of partial black frame insertion with a scanning (switching) LED backlight. The control for it is labeled Smooth Motion, and has three settings, plus off.
The audio menu is pretty conventional, but does include a handy lip sync adjustment to correct for audio latency errors – a technical problem you’d think would be rare, but pops up more often than it should. SRS TruSurround sound is also included in the VF551XVT, as is SRS’ TruVolume peak limiter. This latter processor keeps you from being blasted out of your chair by a loud commercial after a relatively quiet program.
ON THE TEST BENCH
I found most of the factory picture settings for the VF551XVT to be way too bright, and a quick check with my calibration tools confirmed that observation. Factory set brightness modes are in the range of 430 nits, or 126 foot-Lamberts. (That’s tanning lamp territory!) For everyday viewing, you’ll want to crank back the contrast, brightness, and backlight setting considerably to avoid eyestrain. Yes Virginia, there is such a thing as too much brightness…
I selected Normal mode and calibrated the VF551VXT for best dynamic range, a job that is not at all easy since you have both an adjustable backlight and contrast and brightness settings to deal with. Eventually I chose a peak brightness value of 140 nits, which works out to a very-bright 41 foot-Lamberts. The backlight was set right in the middle, at 50.
As I mentioned earlier, all image enhancement or processing settings were turned off for calibration. Even so, it was quite a job to determine what “black” was! With the backlight set too high, “black” is a pretty washed-out gray. Set it too low, and overall image brightness suffers. (After calibration, the lowest average black level I measured was .265 nits, which is about three times higher than a typical plasma TV.)
My initial calibrations resulted in some extremely steep gamma curves measuring close to 3.0. Normal video gamma would be between 2.2 and 2.3, so I had to play with both the brightness control and backlight to find that elusive combination of low grays that gave me a normal gamma, but preserved shadow detail. After several tries, I produced the somewhat inconsistent gamma curve seen in figure 4 – it averages out to a 2.3 value.
Figure 4. Here’s the final gamma curve for the VF551XVT. It’s a little bumpy.
Figure 5. The VF551XVT tracks a given color temperature nicely above 20 IRE.
Contrast measurements were decent. Using a 16-block checkerboard, I measured average (ANSI) contrast at 481:1 and peak contrast within the same test pattern at 589:1. A sequential contrast measurement came to 528:1 – lower than the peak contrast ratio. How is that possible?
Simple – the VF551XVT’s brightness uniformity varies noticeably across a full white test pattern. Taking nine measurements across the screen, you’ll se a variation of about 8% from the highest to lowest reading. Go into the corners, and the difference is as much as 15%.
Color temperature also shifts by quite a bit over that same full white screen. I measured a shift of 634 Kelvin from lowest to highest readings, and that was in two adjacent screen areas. Measured at the center, the VF551XVT tracks a tight grayscale around 6500 Kelvin, as seen in Figure 5.
Now, about the visual “flaw” I mentioned at the start of this review: Like all LCD TVs, the VF551XVT has issues with brightness uniformity over wide viewing angles. On this TV, you will notice that black levels on different parts of the screen increase dramatically with small changes in horizontal and vertical viewing angles, and that’s not good.
The variation in black levels isn’t consistent across the screen. I noticed this immediately while displaying a small area white window test pattern. As I moved my chair left to right from the dead-center “sweet spot”, the opposite screen section started to wash out and become noticeably brighter in areas that should have been black.
The same effect was seen watching nighttime scenes from CSI and Flash Forward – and it was very distracting. With most LCD TVs, as your viewing angle shifts off-axis, the entire screen starts to wash out. Instead, on the VF551XVT, you’ll see “hot” corners, sides, or large portions of the screen as you move slightly off-axis.
To me, that is a major problem as not everyone gets to sit in the best seat in the house. And the best seat has a small viewing “sweet spot” of about 30 degrees. Move beyond that, and you’ll clearly see the changes in black and low gray levels – something you will never see on a plasma TV. (Too bad Vizio stopped selling those!)
I’ll conclude my test bench results by stating that the VF551XVT produces a color gamut that is somewhat larger than the BT.709 standard HDTV gamut, with blue, red, and green all oversaturated. Color management tools would help pull these color points back in and more closely match the desired coordinates, as seen in Figure 6.

This TV produces extremely sharp images that are rich in detail, no matter whether you are looking at a Blu-ray disc or an over-the-air broadcast. I selected scenes from Mission Impossible III to evaluate the judder-correction circuits and also to look at low-level image detail. For motion blur, I watched the Cowboys-Eagles Sunday Night Football game, carried over the air in the 1080i HD format from NBC stations WNBC-DT in New York and WCAU-DT in Philadelphia.
MI III is a great BD for crunch-testing deinterlacing circuits. Start with the Vatican reception scene in Chapter 8 and that famous shot of the camera zooming back as it pans down the closely-spaced stairs; a shot that drives deinterlacing circuits crazy. The VF551XVT handled it with ease.
Turning on the TV’s Smooth Motion processor will reduce the film judder to zero, producing more of a live video feel than film. Vizio’s blur reduction approach is more effective than any 120Hz correction circuits I’ve seen to date, but not as detailed as the few 240Hz processors I’ve checked out. Is this good? Bad? Depends on how much of a film purist you are.
The subsequent kidnapping of bad guy Philip Seymour Hoffman and the destruction of the Lamborghini looked spectacular. But the underground scenes lacked detail in dark areas, a direct consequence of those high black levels. Once again, moving ever-so-slightly in my seat resulted in the washed-out screen effect, which is as distracting to me as DLP color wheel breakup artifacts.
Figures 7a-b. These photos clearly show the off-axis brightness uniformity problem as seen from two different angles.
The football game fared much better (unless you are an Eagles fan), as the average picture level was above middle gray even in the darkest areas. I paid particular attention to close-ups of moving players as the sideline camera panned with them across a busy background. Not only is this an image blurring challenge, you’re also likely to see MPEG blocking artifacts (I did) which are just as much a challenge to filter out without softening the image.
The VF551XVT did a good job here in preserving image detail. Just a slight amount of blur was seen on the tightest shots and fastest zooms, some of which probably originated in the camera itself. So the 240Hz circuit works. It’s still not as crisp as a plasma display, but a big improvement over all of the 120Hz processors I’ve tested.
On the other hand, go lightly on the MPEG noise reduction as it does soften the image slightly. MPEG noise is difficult to eliminate completely – it’s embedded in the digital signal and the only way to minimize it is through expensive, powerful image processing, or through low-cost, high frequency filtering. That’s the approach you’ll find in this TV.
There’s no question about it – for $2,200, you get a lot of TV with plenty of inputs and calibration options. All Vizio TVs are ‘plug and play’ and you can turn it on and start watching with minimal adjustment. Five HDMI ports may be more than you’ll ever need, but where’s the Ethernet connection for Internet video viewing? (Better yet, where’s the wireless Ethernet hookup?)
While the VF551XVT is a nice job by Vizio in most respects, the off-axis image washout was a real turnoff. You’d never see this problem on a plasma TV, and it reminded me of watching rear-projection TVs – you had to sit right in the center to get the best image quality. Keep that in mind before you decide to buy one.
