What is the Panasonic TX-P50VT65B?
Design and Connections
The speaker performance was greatly helped along by the addition of a small subwoofer, secreted somewhere within the confines of the chassis, which helped deliver genuinely defined voice tones and more clout than you would expect, with special effects benefitting significantly from the added low frequency. We generally treat manufacturer’s claims for improved sound quality with a pinch of salt, but Panasonic has actually managed to make good on theirs this time, and the VT65 produces a very pleasing audio performance with enough dynamism to make you think twice about that soundbar purchase.
We’ve always been fans of the one-sheet-of glass design we’ve seen deployed in various top-end TVs and the VT65’s is no disappointment with its integrated bezel which is 3cm wide, to the sides, and extended out by the speaker grilles and a silver trim wraps the whole thing up in stylish fashion. One particular touch we like, this year, is that Panasonic has put the IR sensor a little higher and wider than in previous generations and they’ve also designed the bottom of the screen to have a little more clearance from the base, meaning most soundbars and smaller centre speakers should fit underneath without too many problems. For those that need to know exactly, there’s 129mm to play with. One thing that the 50-inch VT65 holds over the 55” model is the ability for the chassis to swivel on the V-Shaped connector which holds it to the heavy duty brushed metal base stand in attractive fashion.
The AV2 connection doubles up for component and composite video and the AV selection menu lets you manually select which type of signal is being sent, whilst the AV1 input is exclusively for SCART sources. There’s two satellite antennae inputs (for dual tuner recording), a single DTV aerial terminal – internally it’s also dual for Freeview HD recording - and the VT65 also features a service port which we assume can be used in place of the absent RS232 port for the custom install market. It’s also probably worth noting that Panasonic has dropped D-SUB VGA connections for PC’s in 2013, so it’s DVI/HDMI only from here on in.
The TX-P50VT65 ships with two sets of Panasonic’s latest active shutter 3D glasses (TY-ER3D5MA), which seem to have had a slight makeover since last year. The new glasses share the same general design as the earlier ones, so they’re still relatively featherweight and comfortable to wear and they’re also pleasingly tint-free so wont discolour 3D images in any meaningful way. The glasses utilise the new RF standard so you should never have any problem with syncing and they run from watch style batteries so are not rechargeable but in our experience they do last for a long time so if you keep a spare handy, you’re unlikely to get caught out mid movie.
As well as the new content and interface, Panasonic has also launched their new VIERA Remote 2 app. This latest version of their remote app is available for both iOS and Android and includes a redesigned interface and some new features such as access to the apps page. There is also Swipe & Share 2.0 which allows for easier sharing of content between devices, with just a flick of the finger (or thumb). The new Smart Calibration interface Panasonic’s allows full access to the necessary adjustments for a full picture calibration and has the great benefit of not calling up the user menus, which is an annoying trait of the Panasonic’s on two fronts: a) the menus time out too quickly and you’re often left measuring them and b) even their presence at the bottom of the screen affect measurements, albeit only slightly. The only slight drawback is that the Smart Calibration feature only works in conjunction with the ‘Custom’ Viewing Mode; ideally we would have like to have seen it interact with the professional modes too. We’re also very pleased to report that the updated Android version of the new app is now as steady as the iOS version.
The Media Player and Media Server also worked near flawlessly, connecting easily with our home network and a number of devices and providing extensive file support. Overall we found the 2013 version of Panasonic's Smart TV System to be hugely successful in its ambitions of uniting and simplifying the experience and offering bags of content, to boot. We’re increasingly finding ourselves using the apps built-in to TVs, instead of turning to external devices, as they increase in effectiveness to rival them and the VT65 was certainly excellent for our diet of streamed on-demand content. The inclusion of a fully-fledged dual tuner PVR for both Freesat and Freeview HD services is further testament to the TV becoming an all-in-one solution but you need to make sure the external Hard Drive used is USB 3.0 compliant.
Basic SetupThe 50VT65 displayed very similar out of box characteristics to the 55-inch version we tested in the Professional ISFccc viewing modes with Red being excessive in the Greyscale, near white, and Green being mildly dominant in the darker shades. Neither was a particularly troubling tint but having seen the transformation even only fairly minor alterations can make, we knew that the VT65 had lots more to give. As we can see from the CIE to the left, colours were lining up very well to the Rec.709 standard already but red was both under-saturated and too bright whilst the magenta secondary inherited the over-luminance of Red. With a very good CMS and multi-point Gamma and White Balance controls, on board, we shouldn’t have any difficulty in ironing out the kinks.
Despite the similarity in both the pre-calibrated states and end results, we actually had to employ a different calibration strategy to get the 50VT65 to the standard of the 55-inch. We couldn’t get the gamma of the individual RGB channels following each other by going down the normal route of using the 2 point White Balance Sliders and then the 10pt Gamma and White Balance to fine tune. We only show the ‘accumulated’ gamma of all three channels in the Point Graph (to save confusion) and red was clipping badly from 80% stim. We could actually flatten it with the Contrast control, somewhat, but at the expense of light output so we ended up by using the 10pt controls only; to great effect as the charts above demonstrate. We have a literally ruler-flat greyscale and gamma and we’re ready to tickle the colours.
Contrast, Black Levels and Screen UniformityOf course we already knew that the 50VT65B would score in absolutely stellar fashion in this department, without really the need to whip out the Klein K-10 to take measures. Still, we know some of you love the numbers, even if, at these very low levels, minor variances in lighting can slightly affect the readings so take them with that caveat. On a full screen black pattern, our readings varied between 0.004 cd/m2 and 0.005 cd/m2, with the lower figure more prevalent. Either way, that’s very black and effectively means you’ll be at the mercy of your room’s lighting as to how well you can realise the VT65’s incredible dynamic range. In terms of showing mixed content contrast performance, the ANSI checkerboard test is better, if not perfect. Here we found the 50-inch VT out-performing the 55-inch tested in terms of peak light output but (very) marginally behind with its averaged black level. In fact, the 50VT65 was hugely consistent with the black portions all measuring 0.007 cd/m2. So, number-lovers, that’s an On/Off Contrast ratio of about 30,000:1 and an ANSI figure of 13,000:1. We’d fully expect that the brighter whites of the 50VT65 under ANSI conditions are owing to a more aggressive implementation of ABL (Automatic Brightness Limiter) circuitry in the larger panel sizes. In real world terms, we could discern no real practical difference between the two so don’t get hung up on those numbers.
One final word on screen uniformity – the review sample, supplied by a retailer, was free of any banding, green blobs, purple patches or any other unwanted blemishes and the only way we could really spoil it was by doodling with the TouchPen.
Video ProcessingPanasonic’s new Hexa-Processing Engine is seriously good and with a few twiddles of the, otherwise unnecessary, added controls such as MPEG Remaster and Resolution Remaster and Noise Reduction settings, it’s possible to get even low quality content looking relatively good. We hate to admit that’s an important concern but in the days of Smart TV, the internet and YouTube et al, it is a concern for many.
The VT65 passed all the resolution tests with it scaling the images without any loss of detail or unwanted ringing. The Panasonic also scored very highly in the jaggies tests on both discs as well as performing very well on the diagonal interpolation test, with two of the three moving bars appearing smooth and only the bottom most extreme bar showing very slight jaggies. The P50VT65B had no problems correctly detecting both 3:2 (NTSC - USA/Japan) and 2:2 (PAL - European) film cadence, as long as the Film Cadence Mode is turned on.
When it came to 1080i material the 5 correctly deinterlaced and displayed both the video and film resolution tests provided 16:9 Overscan was set to off in the Screen settings. As per last year’s VTs, when it came to 1080p24 content it was able to produce superbly smooth movement and even on the torturous moving wedge tests on the Spears and Munsil disc. The P50VT65 was comfortably capable of hitting reference white and, even more impressively, was able to show 1% black simultaneously, giving a staggering dynamic range.
Panasonic’s latest 3000Hz Focused Field Drive meant it was able to ace the FPD Benchmark disc, where the full 1080 lines of resolution were clearly visible on the moving tests. The VT65 includes an Intelligent Frame Creation setting for 50 and 60Hz content, which is a frame interpolation feature that offers a choice of Off/Min/Mid/Max. As Steve found with the GT60, the Min setting does very little with motion perhaps appearing just ever so slightly clearer but we honestly never felt a pressing need to engage it, at all. That goes double (maybe 24x) for the 24p Smooth Film function which makes film appear as video shot on a (not very good) handheld camera.

Panasonic TX-P50VT65B Picture Quality 2D
The answer to the question above will be those that can’t live with some of the natural idiosyncrasies of plasma technology and the VT65 is subject to some of those. Probably chief amongst those weaknesses is a tendency to show up a spot of dynamic false contouring (DFC). It’s most easily seen on subjects’ faces where green and magenta fringing might suddenly appear on cheek or jawbones but it does happen in other situations. We have to say that having spent a good amount of time with two VT65’s, instances really are very rare. We’ve numerous test clips and items on the TiVo hard-drive we’ve been using to check for DFC on the Panasonic plasma TVs for years, and by checking those, we’d say they’ve improved it by about 50 percent. We don’t wish to highlight it as a major flaw, most won’t notice, and few will care, but we know how discerning our readership can be. The only other thing worth checking for is your susceptibility to PDP flicker, because that will be there for some. Only a demo will answer that one for you!
And we’ve not even mentioned the motion handling, which is particularly improved with 50Hz content this year. The Panasonic’s have always been buttery smooth with 60Hz and 24p signals so it’s great to see them finally conquer the format used in our broadcasting and optical disc media; the VT65 is a thing of beauty when action is flying around the screen, maintaining fine detail and resolution, even with the most demanding of action movies or sports. OK, if you stick your face close to the screen, you might be able to see a teensy weensy bit of double edging, here and there, but we’d hope there’s no one out there watching like that. Simply put the Panasonic TX-P50VT65 delivers on all fronts with unbelievable dynamic range, flowing and fluid motion handling and a colour palette so natural, you could swear you were in amongst the on-screen action.
Picture Quality 3D
Not only has Panasonic improved upon the 2D to great effect, there’s a nice boost in 3D performance too. We again popped our copy of The Hobbit in to the player and returned to Lonely Mountain where the VT65 unearthed a treasure chest of 3D thrills. The use of positive parallax (depth) in the 3D version is truly outstanding and the VT65 delivered it with total assurance, creating a tremendously enveloping landscape with totally believable distant horizons and towering trolls that truly intimidated. The VT65 is not short of brightness in 3D either and the THX Cinema 3D provides a very decent starting point for those not watching a calibrated 3D display. Motion handling, as with the 2D images, was also mostly fantastic and crosstalk was at a minimum.
Turning away from frame packed 1080p24 Blu-ray, we put the VT65 through its paces with side-by-side content at 50Hz, i.e. what we see from our broadcasters, and there’s no better test than the Wimbledon footage shot by the BBC. Again, the VT65 came up smelling of roses with just the faintest hint of crosstalk on the tramlines as balls travelled with fierce velocity at diagonal angles across the net. Motion was similarly excellent to the Blu-ray presentations and the detail packed in with either format, was utterly spellbinding, at times. As a personal note, with anything but a single lamp on in the room, I was able to detect a fair bit of flicker but you really shouldn’t be watching 3D in a well-lit room.

Panasonic TX-P50VT65B (VT65) Plasma TV Review
Although the general interface is pleasingly de-cluttered, the new Picture Menu holds a huge array of controls – some necessary and useful, others not – but the all-important advanced calibration controls are both plentiful and excellent, allowing us to extract supremely accurate images from the VT65. Not only were colours sublimely natural, the Panasonic 2013 Plasma TV range is absolutely setting the current bar for black levels, dynamic range and motion handling, producing such beautifully filmic images you could be forgiven for thinking you’d be transported to a cinema of yesteryear. Not that the 50VT65 can’t hold its own in more illuminated surroundings; the combination of an incredibly effective light filter and new panel brightness settings meant we could have both accuracy and brightness. Take that LED. There’s almost nothing to spoil the party bar the occasional spot of false contouring but we’re getting very close to the limits of what plasma technology can feasibly achieve.
The Panasonic TX-P50VT65B is about all you could ever want from a TV. It has looks and pictures to die for, lots of useful apps and features and it’s incredibly easy to use thanks to a well-designed interface and control schemes. To break it down even further – the Panasonic VT65B is the best consumer grade TV currently available so we’ve no choice but to award it a thoroughly deserved AVForums Reference Status. Bring it on OLED!
