Panasonic's launched the world's largest 3D tv. It's a 152 incher with a 4096 x 2160 definition, self-illuminating, full HD 3D plasma display. Panasonic announced this television earlier this year, in January at CES, and it's now available in the Indian market. To develop the new model, Panasonic used its technologies employed in its VIERA Full HD 3D plasma televisions that were launched in the market this year. The technologies include a native contrast ratio of 5,000,000:1 for better black reproduction; a high speed driving technology to achieve the PDP's (plasma display panel) full moving picture resolution; and a crosstalk reduction technology, a requirement for producing clear and crisp 3D images. This television is priced Rs. 3.5 crore.
Manish Sharma, Director- Marketing, Panasonic India said "From 152-inch LCD to 19-inch full-HD 3D plasma display, Panasonic now offers its customers the widest range to choose from. The launch is a part of the global strategy to create new viewing environments for our customers and also to create a new video industry based around 3D plasma displays by accelerating 3D-based innovations." So, here it is: the 50-inch version of the Panasonic VT30, the Japanese manufacturer’s top-end 3D Plasma TV series for 2011. The TX-P50VT30B features a Full HD panel (of course), 4 HDMI inputs, a reflection-killing screen filter (part of the “Infinite Black Pro” branding), the THX Certification seal of approval for both 2D and 3D modes, and basically all the ISF-approved calibration controls you could hope for, including full 10-point Greyscale and Gamma correction, and a fully-fledged three-axis colour management system (CMS).The UK model (reviewed here) features connectivity for the Freesat service as well as digital terrestrial HDTV (Freeview). Furthermore, in all European countries, the Panasonic Viera VT30 3DTVs ship with two pairs of active-shutter glasses 3D in the box (many other territories around the world receive only one pair). Let’s see if all of this adds up to make the TX-P50VT30 a must have 3D television.DesignTo those of us who aren’t users of Apple’s tablet device, the similarity will probably have passed us by, but after it’s pointed out, it’s hard to deny that with its rounded edges, shiny glass surface and silver outer trim, the Panasonic TX-P50VT30B resembles a giant iPad. We don’t imagine anyone will find fault with the design: it’s sleek enough to appeal to most users and understated enough to be inoffensive. Our usual complaint – the usage of gloss black material – isn’t really an issue here because the entire panel is covered in a sheet of glass, making it difficult to scratch (something that can’t be said for the gloss black plastic used on many HDTVs). However, a reflection-free bezel is recommended for use with 3D TV to avoid drawing attention to the edges of the frame.The 50VT30 is only a few centimetres thin (although it extends out at its base to allow for larger speakers), and sits securely on top of its supplied tabletop stand.
The remote control supplied with the UK (and other European) models is fairly sleek, and feels heavier than the more basic remote control supplied with other Panasonic Plasma TVs. We like both remotes very much, although the Viera VT30′s has the advantage of having some of its buttons back-lit in red. In case you’re wondering, the remotes are interchangeable (at least in terms of basic functionality – we haven’t tested every single button).ConnectionsThe Panasonic TX-P50VT30 features 4 HDMI inputs, connections for the satellite and terrestrial tuners, and inputs for older analogue interfaces, which require break-out adapter cables (included in the box). There is no VGA (“PC”) input on the European models, something we don’t think will be missed given that the HDMI connections are up to this task. Gamers expecting to hook their Sega Dreamcasts (which, as a pre-HDTV console, relies on VGA for its highest quality output) may be the only group who mourns the loss of this input (myself included).Using our Klein Instruments K-10 meter, we were able to use the pre-calibration measurements together with the TX-P50VT30B’s [White Balance] menu to offset and remove any errors, resulting in perceptibly perfect greyscale shades. However, during this process, we noticed something strange. If we stepped through all stimulus levels – 0, 10, 20, etc. – we would sometimes get a perfect measurement in the 10% position, but at other times, the 10% measurement would be overly tinted – strange behaviour which we confirmed by eye. The culprit turned out to be the low-brightness shifting we’ve noticed with other 2011 Panasonic Plasmas. It turns out that, if the user brings up the TV’s menu (which is necessary to adjust the [White Balance] settings, unless the calibrator is using CalMan Professional to directly alter the television’s settings via a PC), a small luminance shift occurs, which also alters the Greyscale tracking in dark shades. Our first work-around was to bring up the menu, make the necessary adjustment, clear the menu, display a fully black screen, then return to the 10% grey patch and make the measurement again. Of course, while this results in linear Greyscale measurements on the above chart, it’s a good demonstration of the fact that real-world performance will be prone to this sort of unpredictability, which may result in some mild errors still creeping in. However, we don’t think some Greyscale shifting in shadowed areas will trouble anyone too much.As a result, we switched to APL (Average Picture Level) test patterns to carry out the calibration. Although the behaviour of the TX-P50VT30 is somewhat unpredictable in this regard, APL patterns will surely approximate real-world programme material better than the traditional windowed patterns we normally use to calibrate Plasma televisions.
