I’m a proud owner of the TH-42PX60U, and yes I too went to Circuit City and Best buy to check this unit out. First I went to Circuit City and just like you I immediately notice the clay face when a close up of people appeared on to the screen, there was also a lot of graininess showing as well. This unit was on display side by side next to last years model of the 42” EDTV version, I was shocked to see that the EDTV’s PQ was much better and knew then something was wrong, I asked the sales guy for the remote to see if I could play with the settings to make things better, no luck. I headed to Best Buy right after I left Circuit City and they indeed had a remote. Immediately taking it out of Vivid mode the Clay face and the graininess disappeared and the PQ was just stunning! So basically Vivid mode = Torch mode, and I recommend taking it out of Vivid as soon as you get this unit out of the box and set up. There are three modes to choose from, Vivid, Standard and Cinema. Mine is currently set to Cinema with the contrast and brightness settings down for the duration of the break-in period (100 hrs).
This units Contrast (Picture) is much brighter than last years model which I believe causes the clay face and graininess when in vivid mode, having a brighter picture only means good things for this new panel because if this unit does indeed last up to 60,000 hrs which then should be at its half brightness according to Panasonic then our displays will then be at previous models brightness out of the box later in its panels life span.
Just another note, when in Vivid mode I believe that Sharpness is also cranked up way high which also contributes to the clay face and the graininess. With all that said, this
Panel truly displays stunning PQ with the right settings.
