Hi guys, just thought I'd pass back some opinions on the AX902 after spending considerable time with one during a recent calibration. I was principally calibrating it in conjunction with a Lumagen Radiance 2143, the idea being to make use of the 2143's 17x17x17 LUT and superb upscaling capabilities. However, it was by no means an easy ride. It took me quite some time to work out why, instead of the expected perfect images with the Lumagen, the calibration was continually messed up. The unacceptably high input lag of the AX902 resulted in a mistiming of the presentation of the patterns and the meter readings. Even with Game Mode switched on readings were on a knife edge as the AX902 could take several several seconds to become stable in between patterns. This naturally leads me to conclude, as have several reviewers, that if you are interested in gaming the AX902 is probably not the TV of choice. In the end I managed to get decent 3d LUTs with an excellent picture via the Lumagen but Panasonic desperately need to bring out a firmware update, as Samsung have recently done with the HU8500, to reduce input lag. I also calibrated several modes, both 2d and 3d, using the AX902s own calibration controls. I am happy to report that these work superbly and also deliver great image accuracy.
Backlight uniformity was ok, with moderate bright patches in certain areas - particularly in the top left hand corner. Black levels without the dimming engaged were mediocre. However, engaging the dimming made a big difference to black level and is simply essential on this set. Still, even with dimming engaged the black levels and contrast on the AX902 aren't in plasma league - so I get Steve Wither's point. Otherwise, 2d picture performance was very pleasing. I was most impressed by the 3d performance which uses passive glasses. This TV puts out a really bright, colour accurate 3d picture with oodles of depth and minimal crosstalk. It's simply terrific in 3d.
