Hi all, I am running Windows 7/64 with a 8800 GTS and the 196.21 driver on a Samsung P2370 1920x1080 resolution. I am getting very poor video playback. I know it's not a codec issue now. I'll explain why in a bit. The shadows on the videos look like 16 bit. Instead of a smooth transition from dark to light there is a 'rainbow' effect of a few colors. Similar to 16 bit. While surfing to find the problem I came across a website that made it all clear. I scrolled down and found that pictures behave the same way when moved. Here is the site. Scroll down about 1/4th to the picture with the fish. Scroll lightly up and down. On my XP machine the picture stays solid. On Windows 7 the colors (where they fade) flicker as I scroll. http://help.artaro.eu/index.php/windows-7/the-basics-of-windows-7/desktop-start-menu-folders-and-nternet-explorer-in-windows-7.html I tried the default Windows 7 drivers with the same result. Tried 16 bit color and the flickering is not as bad. Please tell me if you guys are getting this on Win 7 and if you think it's a display driver issue. Thanks for your help!
