Best 50" picture quality in the U.S.
By Andon M. Coleman
With SONY and JVC no longer manufacturing their phenomenal high-end CRT HDTVs, and Pioneer out of the Plasma business, the pursuit of picture quality is not as simple as it once was. Rest assured, however, that there are still a handful of manufacturers (i.e. Panasonic, Samsung, LG, ...) still investing in Plasma technology, because LCD is a giant leap backwards in terms of picture quality. When Pioneer - the previous undisputed leader in picture quality - left the industry, they sold their Plasma technology to Panasonic. While the amount of Pioneer technology (if any) present in Panasonic's current line-up is a matter of debate, most critics will agree that Panasonic currently holds the crown for picture quality.Viera Size Segmentation (VT30 vs. GT30 vs. ST30)------------------------------------------------I was in the market for a VT30 this year... however, in the United States, Panasonic's size options are quite restrictive. In Europe, all lines of plasma from the X up to VT are available in 42", which is the perfect size for me.In the United States, each of the 3D model lines has a different starting size: VT30: 55" - 65" (Industry leading black level, less buzzing, better speakers, 96 Hz mode for 24p, ISF calibration, ...) GT30: 50" - 65" (Better black level, +1 HDMI port and VGA input, THX certified) ST30: 42" - 65" (Entry-level 3D TV) S30: 42" - 60" (1080p 2D plasma, worse motion clarity than ST30 and no 3D support) X3: 42" - 50" (720p 2D plasma)Unfortunately, I can barely fit a 50" TV where I have my GT30. I made the conscious choice of buying a TV slightly larger than I would have liked, because the GT30 buys you THX mode (which does a _really_ good job with skintones), an extra HDMI port, and a slightly lower black level than the ST30.Picture Quality---------------Getting back to picture quality, I have a SONY Super Fine Pitch FD Trinitron (CRT) set in my bedroom that I use as a benchmark for image quality.The GT30 does not have the pure black level or white performance of the CRT (or even many local dimming LCDs). However, color accuracy and black gradiation (i.e. being able to see fine details in shadowed scenes) are actually better than my calibrated CRT.Unenhanced motion clarity is indistinguishable between the two sets, and the GT30 earns a lot in this respect when it comes to displaying 24 fps material (48 Hz mode causes flickering, but even with simple 3:2 pull-down, the TV displays 24p video well).Panasonic has added a more advanced Motion Smoother this year, with two levels - it creates artificial motion enhancement similar to LCD 120/240 Hz, and therefore has limited appeal.Physical Appearance-------------------Typically I do not care about the physical appearance of a television (which is why I still prefer high-end CRTs to flat panels), but the design of this TV is definitely worth mentioning... compared to last year's GT25 model, this TV is lightyears ahead.The bezel has been shrunken on all sides of the panel, and the depth is equally impressive. Were it not for the speakers, and clunky stand, this TV would be about an inch deep. As a result, the television requires "break out" cables to attach analog audio/video devices, and the total number of analog inputs has been reduced to 3 (Component, Composite and VGA D-Sub). This does not bother me at all, since the only analog device I have connected to any of my TVs is a Nintendo Wii. The extra HDMI port more than makes up for it.I would also like to give kudos to Panasonic for putting the power button on the FRONT of the TV this year (it was on the side last year).Long-term Value (Viera Connect)-------------------------------Viera Connect is a promising new feature for 2011, that is essentially an evolution of Viera Cast.Consumers can look forward to a growing software base in the future (as Software Engineers like myself develop software for the new open platform). The beauty of this new platform is that it operates independantly of official firmware release schedules. This is important, because firmware updates for aging products are few and far between - 2010 and older Viera models will likely NEVER receive support for Hulu, etc...With this TV, two or three years from now, consumers can still download new or updated Viera Connect applications from the Viera Connect marketplace. Another thing I found nice about Viera Connect's marketplace, is that you can buy TV accessories (such as 3D glasses, SD cards, etc...) directly from software built-in to the TV, and rest assured that the product is compatible with your particular model.Sound-----Sound quality leaves room for improvement. This being the second-to-highest model from Panasonic, lacks the sub-woofer and higher quality speakers found on the VT line.Adding insult to injury, US Viera televisions do not have analog audio out, so to improve the audio quality you must connect them to an A/V receiver (which also draws a lot of power) that supports optical S/PDIF.In future years, I hope that Panasonic will consider improving the sound quality on the GT line.Power Consumption-----------------Power consumption is good, but definitely not great. This is the only performance measurement that local dimming LED backlight LCDs come out on top in. That said, Panasonic has redesigned the construction of their panels this year, to improve phosphor response time (reduces 3D cross-talk), and improve luminous efficiency. Remember that this TV uses tinted 3D glasses, which darkens the picture... so brightness is important in 3D.As a result, brightness is up, and power consumption is down vs. last year's model. Unfortunately, one consequence of the new design is "fluctuating brightness," which occurs when the TV transitions from a bright scene to a dark scene - in extreme cases, it can take the TV multiple frames to recognize the change in brightness and adjust its image processing. This was irritating at first, but I hardly notice it anymore.Plasma Buzz-----------On a final note, I have noticed a lot of people complaining about plasma buzz. I feel obligated to point out that the buzz is especially bad within the first 100-200 hours of operation, and decreases somewhat over time.There are a number of factors that play into the buzzing, including altitude, viewing distance and picture settings. Granted operating altitude is not easy to change, but the buzzing can be reduced by sitting farther from the TV set, and dialing down the contrast setting (buzzing is directly related to how bright an image is).A lot of people have TVs too large for their viewing distance and have contrast set way too high, and only ever realize it when plasma buzzing or dithering becomes a nusiance.Pros and Cons------------------Pros:----- Plasma image quality * Pure black level is not as good as CRT or local dimming LCD, but... images with light and dark areas really shine --> No blooming between nearby light and dark areas (LCD) --> No image geometry warping related to brightness (CRT) * Excellent motion clarity without artificial techniques like 120/240 Hz THX mode * Accurate skintones * Almost no picture setting tweaks required to get exceptionally good image quality Consistent black level * Panasonic claims that the black level will not rise after 1000+ hours of operation with 2011 models, due to manufacturing changes. Power consumption vs. Screen brightness SIGNIFICANTLY improved over 2010 models * In fact, it is so good that the 50" GT30 actually qualifies for Energy Star 4.0 Viera Connect * New in 2011, free/paid applications can be downloaded through the TV and the selection of applications will grow over time.-----Cons:----- Viera model lines segmented by size in the US * Could mean buying a TV that is too large Average speaker quality on ST30/GT30 * US Viera models do not have analog audio out --> Requires a dedicated power-hungry A/V receiver to improve on TV's speakers... Power consumption * Improved in 2011, but still nowhere near local dimming LCD performance Fluctuating brightness * Movie enthusiasts may find the delay in bright image processing frustrating... --> I have found the issue has almost no negative impact on gaming performance, or general TV viewing. Netflix Performance * Given the state of the Netflix app on Viera Connect as of June 2011, audio noticably stutters... --> Mitigated by the fact that Viera Connect will allow users to download an updated version of the Netflix app whenever the bug is fixed.Calibration-----------For those who are interested, I have had my GT30 professionally calibrated in THX mode.If you do not want to shell out $300+ to schedule a calibration on your set, but still want the best picture quality possible, the most important thing you can do is dial the color setting down to around 45. The default THX settings over saturate colors, and if you become used to the over saturated colors, you will never appreciate the advantages of a properly calibrated THX mode. Also, do not use C.A.T.S.! If you have a viewing environment that has varying levels of external light, you would be much better off maintaining two sets of picture settings. In my case, between night and day, all I need to do is adjust my contrast from 60 to 45. C.A.T.S. can detect differences in brightness, but it messes with more than just the white level.You may be tempted to set the Black Level setting in "Advanced picture" properties to dark because it looks more natural, but this causes black crushing (loss of detail in dark video). Try to learn to live with lighter blacks (this can be especially difficult if you are used to high-end CRTs) and you will begin to appreciate the amazing black performance of Plasma technology.

Unbelievable Picture
By C. Wilson
The picture quality this TV puts out is crazy good. Colors are bright and vibrant without being over saturated and unrealistic. Blacks are inky black, and shadow detail is great as well. One of the reasons I bought the GT30 over the ST30 is the THX mode which gives really good out of the box picture without any aftermarket calibration. If you're into tweaking the picture though, there are two professional picture modes that allow very in depth picture controls.1080P Source Material with a high bitrate (such as blurays or Vudu HDX) look incredibly sharp and stunning, while not looking sharp to the point of unrealism as some LCD's look. 720P sources look very good as well if a bit softer. 480i/p sources look alright. I only spent a few minutes watching SD and the experience was unexpectedly unimpressive. Motion on the GT30 looks very smooth and realistic without displaying the terrible "soap opera effect" that 120/240Hz LCD's seem to suffer from.I tried using the Viera Cast software that Panasonic builds into these Tv's and I found to be pretty laggy. It wasn't very responsive and I found the design to be a little on the ugly side. Vizio and Samsung have much more polished media platforms built into their Tvs. It's possible Panasonic will improve performance with firmware updates in the future. If I was planning on using Viera Cast I would mark my score down but I have a Media Center PC and PS3 that replace all the functionality Viera Cast offers.3D performance is very good. So far I've watched Tron Legacy on 3D bluray and played some 3D PS3 games; the 3D picture is very immersive and THX color accuracy remains very good in 3D mode. I've had bad experiences with 3D crosstalk on a friend's Samsung C7000 LCD and it can get very annoying and distracting. Thankfully I haven't experienced any of that on the GT30 in a dark or light viewing environments.I've heard some early reports of the GT30 exhibiting floating blacks when viewing material that changes from a darker to a lighter scene suddenly. I haven't experienced any of this. I watched Black Swan on bluray to test this and black levels remained dark and consistent throughout with no slight jumps in brightness.I'm also very impressed with the design of the GT30. It's about as thin as my Motorola Droid and it looks stunning mounted on my wall. Panasonic has traditionally lagged behind the likes of Sony and Samsung when it comes to the design of their Tv's but they really stepped up their game with the GT30. Having a TV that looks almost as stunning when turned off as it does when turned on is an unexpected plus.Overall the GT30 is an incredible TV that makes no compromises when it comes to picture quality. If you want to spend more money, the VT30 it will probably improve upon the GT30 in some way when it's released but I'm having a hard time coming up with things they could improve outside of their Viera Cast platform.

Fluctuating brightness no longer a problem; great for games
By E. J. Paul
Admittedly, I was hesitant to purchase this TV because of the mixed reviews. Many people here (and on various forums and review sites) complained of distracting brightness fluctuations that significantly detracted from the viewing experience. I decided to just go with it and I must say I don't regret my purchase at all.First, yes, the brightness fluctuations were distracting. Notice the past-tense "were" there; as in, the fluctuations are no longer distracting because they are no longer a problem. For North America, Panasonic has acknowledged and addressed the fluctuations. For sets manufactured prior to August 2011 a repair is available in the form of an SD card software update or a very simple hardware replacement (pre-updated hardware for non-Panasonic repair techs as an alternative to updating the software with an SD card). So, don't let the looming shadow of brightness fluctuations deter you from this TV--if you get a set and it is a problem, call Panasonic and they'll fix it. On the other hand, you may not even notice them at all. So again, don't let it hold you back.I discovered this TV while looking for an affordable way to pick up a quality 3D HDTV, mostly for gaming. 3D performance is very good. Many have claimed this TV is crosstalk free (crosstalk is the phenomenon where the image intended for only one eye bleeds a bit into the wrong eye causing a double-image effect), but it simply is not; however, the crosstalk is generally not very noticeable in movies and games and in the case of games you can usually adjust the strength of the 3D effect to somewhat mitigate the crosstalk. For anyone wondering if plasma tech is ok for games the answer is yes, it is fine. Some people recommend about 100 hours of "break in" before leaving any static images on the screen. I don't know if this is technically necessary but there's nothing wrong with being cautious and conservative...100 hours really isn't much time for a TV at all. Some with a critical eye may occasionally notice image retention, but it is temporary. Just be mindful about leaving static images on the screen for long periods of time (for example, don't leave a game paused for several hours...just turn off your TV if you won't be using it, you'll save electricity). Many games have health bars, maps, or other fixed images on the screen, but in my experience these don't cause long-term problems: first, the TV will imperceptibly shift pixels around to keep them changing; second, most games have cutscenes, pauses, and transitions that change up the picture frequently enough that it won't really matter. Again, just be mindful and you shouldn't have any problems.This set replaced a Sony XBR LCD from 2008 and so far (2 months of ownership) I don't miss LCDs at all. Frankly, at this screen size LED backlit 3D capable LCDs are just too cost prohibitive in my opinion. Yes the power consumption is higher than an LED lit LCD so the long-term cost of ownership is higher in that respect, but I haven't noticed any difference in my electricity bill compared to my CCFL lit LCD; so, if you're coming from an older LCD the power consumption probably won't be a lot different.
