[QUOTE="Verbal, post: 23623, member: 15517"] I confirm this problem on both 1.2.0 and 1.3.0 using radeon 9200 SE with only tv-out to a regular ntsc CRT. I have installed the latest directx 9.0c and Winxp sp2, all updates. Here's my experience. Fullscreen openGL and direxctx apps used to be too bright. In the radeon control panel i dialed back the gamma and it corrected the problem. For example, space simulator Celestia (which has a lot of black) now actually looks black. However, I notice that when playing video files, black is not black but noticeably gray, as other posters have noted. Specifically, playing a DVD rip that is letterboxed, the top black bars are slightly grey, and then the black frames at the start of the movies are very grey. The brightness is way too high, as white in the movie almost glows. When I start a dvd or a video, I notice the brightness increasese significantly on the menu sceen for an instant, and then goes to full screen video. What is being called when full screen video runs? Is it MP10? FFdshow? something else? [/QUOTE]
