Hey everyone, after spending an hour of searching and reading I figured it's best to post an issue I'm experiencing and simply can not seem to solve. A couple of weeks ago I bought a Pioneer 435XDE. Major reason was the ability of this screen to be connected towards a PC, which was a dream of mine with HDTV media files. After setting up a fast PC through VGA to the screen I was a little dissapointed about image quality. To be honest I expected far more. A couple of days ago I decided to boot the VGA connection and go for a Digital connection between the PC (DVD-D towards HDMI) with a redicuklously expensive yet high-end cable. The image difference (quality) compared to the analog VGA connecting is breathtaking. One problem though. Playing back HD movies (.ts files etc) while displayed brilliantly has a very negative side-effect. At random interfalls the plasma screen flickers a little. I can only describe it as brightness/contrast levels that quickly flickers at random. And I'm not talking about your standard interlace flicker here .. This only happens during media playback. In windows desktop this flicker does not occur. I tried many pieces of software versus settings. Resolutions, overscan/undercan .. No I have pretty much looked into everything. I even connected different PC's, Graphics cards (Radeon x850 XT / GeForce 6600 / GeForce 6800) tested several resolutions and so on but I just can't get rid of that random flicker and it's slowly driving me mad. Interestingly enough at 1280x720 @ 60 Hz I have this flickering. At 1280x720 @ 50 Hz the flickering seems to be gone. Yet movie playback is a mess and stutters massively. The HTPC build right now is equipped with a GeForce 6800 GT, Pentium 4 3.6 GHz CPU and has 1 GB memory. This system is cinnected over DVI towards HDMI. Does anyone have a clue what this might be the cause of this ? Because I am getting pretty desperate here. Many thanks for any insight you can get me.
