Panasonic TH-50PZ800U

Design
In photos, the Panasonic TH-50PZ800U looks a lot like every other HDTV on the market: a glossy black rectangle. In person, however, it's a lot more striking and less glossy. In fact, the black frame around the screen isn't glossy at all, it's simply fronted by a big pane of glass that lends the panel a somewhat more sophisticated look than a typical set, where the frame is raised a quarter inch or so from the surface of the screen. Below the screen, the Panasonic's frame has what resembles a pair of pursed lips that protrude forward, bearing the logo and hiding a set of inputs behind a flip-down door.

The stand looks identical to the sloped number common to lower-end 2008 Panasonic plasmas such as the TH-46PZ85U and the TH-42PX80U, but unlike those stands, this one swivels, courtesy of a lazy-Susan-like base hidden underneath. Including stand, the TH-50PZ800U measures 49.9 inches wide by 33.4 inches tall by 15.3 inches deep and weighs 92.6 pounds. Divested of stand, its size shrinks to 49.9 inches wide by 31.2 inches tall by 4.1 inches deep and its weight shrinks to 81.6 pounds.

Panasonic's remote remains the same as last year, and we remain fans of its layout. The medium-length wand groups the distinct sets of right-sized buttons in an easy-to-feel arrangement, and although we'd have liked to see some backlighting, we didn't really miss it after a few minutes of becoming familiar with the button arrangement.

A familiar yellow-on-blue menu system leads to the television's setup functions, and although the graphics lack the panache of a Sony or a Samsung menu, navigation was intuitive enough. We liked that the company renamed its previously confusing "Normal" command to "Reset," which more accurately describes what it does to your picture settings.

Features
As we mentioned, the big step-up feature between Panasonic's TH-PZ85U series and the TH-PZ800U models such as this is THX Display Certification. The certification involves testing in a number of categories such as contrast ratio and color accuracy, according to THX, and the TH-50PZ800U has a special THX picture preset that, when engaged, causes the TV's picture to comply with the certification. We'll detail its effects in the Performance section below, and we describe more about the certification itself in this blog post.

Performance
Thanks primarily to the accuracy of its THX picture mode, the TH-50PZ800U is one of the best-performing plasmas we've ever tested. It can't quite match the depth of black evinced by Pioneer's Kuro plasmas, such as the PDP-5080HD, but it most other areas, including color accuracy and uniformity, it's superior.

We typically go on and on about calibration but with the TH-50PZ800U we didn't have to do much beyond increasing its contrast control a bit to approach our 40 footlambert baseline light output. Compared with other picture modes and to the company's own TH-46PZ85U, THX on the PZ800U delivered superior color temperature and especially primary color accuracy, and despite the fact that THX mode didn't pass blacker-than-black parts of the video signal (while the Custom mode did), we left brightness alone for optimal performance.
