The Panasonic LC-32LX85 is one of the better performers at its size in the entry-level, 720p-resolution LCD category. Color accuracy and black level performance are its main strengths, while color decoding and standard-definition processing are not.
I didn't have to make too many adjustments during the user menu calibration to get the little TV looking its best. Since there are no custom color temperature controls in the user menu, I simply chose the best picture mode (Custom) and color temperature preset (Warm) and then tweaked the remainder of the basic picture controls. Afterward I was pleasantly surprised at the accuracy of the grayscale; you can click here to access my full picture settings. For my comparison I looked at the Panasonic alongside the Sony KDL-32M4000, the Westinghouse VK-40F580D and the Vizio VP322, two LCDs and a 32-inch plasma respectively.
Black level: Blacks are reasonably good for an inexpensive LCD flat-panel TV, and deeper than either the Sony or the Vizio, although not quite as deep as the Westinghouse. The Panasonic also delivers the blacker-than-black video signals that many more expensive displays cannot, which helps lead to improved shadow detail. Chapter two of X-Men: The Last Stand showed off the LC-32LX85's compelling blacks very nicely. This high-contrast scene takes place at night, with bright explosions going off to provide a good look at an HDTV's shadow detail capability. There was plenty of fine detail in the background dark areas of the picture. The black areas of the picture were deep, rich, and inky, and the scene was relatively free of low-level noise.
Color accuracy: As you can see from the Geek Box, grayscale tracking in the Warm color temperature preset was impressive, and the primary colors of red, green, and blue also measured reasonably close to the HDTV standard, which is unusual even in some expensive flat-panel displays. Color decoding does push red a bit though, so we had to desaturate the color somewhat and remove some of the picture's punch. Colors still appeared vibrant, however, and skin tones looked quite natural. Chapter four of the awesome transfer of I, Robot proved an excellent scene to show off the Panasonic's contrast ratio--good blacks and whites creating a snappy picture--as well as its accurate color reproduction.
Video processing: Unlike most modern HDTVs the LC-32LX85 doesn't accept 1080p sources, so my evaluation had to be with all HD sources set to 1080i. The set lacks an aspect ratio that provides for zero overscan, which would be a bigger issue if it were a 1080p resolution panel, but really isn't a big deal the panel has only a 720p resolution. The video processing does roll off the high-frequency video somewhat, a common flaw with many flat-panel sets on the market today.
Uniformity: White-field uniformity was reasonably good on this panel, and that is saying something for an LCD. As you may know LCD display technologies, whether flat panel or projection, suffer from poor white-field uniformity. As a result you may see red and blue splotches in scenes that are primarily white like the ice in a hockey game or a movie like Ice Age. This Panasonic, while not perfect, was better than most in this performance test.
Standard-definition: The Panasonic is a mediocre performer with standard-def material. It didn't resolve every line of horizontal resolution according to the charts on the HQV disc, and as a result some images appeared a bit softer than normal. It did a below-average job of smoothing out jaggies on rotating diagonal lines, and there were a good number of such artifacts in a waving American flag. The set's noise reduction, on the other hand, was very good at cleaning up moving motes in low-quality images of skies and sunsets, and the set engaged 2:3 pull-down detection quickly and effectively.
PC: Absent a VGA-style PC input I attempted to test the Panasonic's capability to handle digital signals from a PC via its HDMI jack. The best resolution the video card allowed was 1,280x768, which is short of the set's native resolution, and there was enough overscan that important areas of the screen, including the Windows taskbar, were obscured. People who want a PC display should probably choose another set.
