Amazon delivered my 60 inch GT30 (without a broken screen this time) and I've been very happy UNTIL I popped in my Blu-Ray copy of David Gilmour's Remember That Night and played the track echoes. There are some very bright concert lighting effects that switch quickly on this track and something in my video chain can't handle them. I get stutter, lost frames, and quasi-test pattern artifacts during the most intense screen activity. My previous Grand Wega 720p did not have these problems. I have reduced the output resolution on my OPPO to 720P and the same artifacts persist.
I am running in THX Mode with contrast and brightness at 50 (will do this for a bit longer due to concerns about burn-in)
My player is an Oppo BDP-95 which I have one hdmi connected to the GT30 and the other to an AVR (Emotiva UMC-1) for sound and occasional video (the AVR can not pass a 3d signal). The artifacts persist when I switch to the hdmi through the AVR.
Again the two new elements in the video chain are 1) the GT30 and 2) adding a second HDMI connection from the OPPO (in this case directly to the GT 30 but the artifacts persist on both hdmi connections).
Well, it appears that whatever happened above somehow damaged my Viera. Picture quality is slightly less sharp and Blu-Rays that I watched the day before this event look less clear. It is almost like going from 1080P to 720P (but that isn't what has happened). I've contacted Panasonic and they aren't quite sure what to do yet. Any thoughts out there from anyone as to what the heck happened here? To be clear, I haven't fooled around with anything in the service menu and was running in THX mode with contrast and brightness reduced to 50.
I'm still having trouble seeing how this represents
a definite display problem. The artifacts you were describing
sound more like compression artifacts or maybe
HDMI handshaking artifacts.
Now the main issue is that the image is
a little soft? Like the difference b/w 720p and
1080? That's a pretty subtle change--are you
sure? I guess anything's possible, but it seems
very unlikely to me that what you described happening
would have caused any damage at all--and in that
unlikely event the damage would then produce
just a subtle softening?
I'd use something like a test disc to objectively
test the display resolution. HD-DVE, Spears
and Muncil, and HQV all have resolution test patterns. I'd also
hook the Oppo directly to the display for the testing.
Oh, and I agree the standard mode thing they told
you is total BS--I'm just not sure you're barking up
the right tree here.
