[QUOTE="HomeY, post: 1281643, member: 68365"] For madVR you should set the output in Nvidia Control Panel to full RGB. 8bit for the refreshrates above 25Hz and 12bit for the 23.976 / 24Hz refreshrates to make full usage of the deep colours. [ATTACH type="full" width="306px" alt="nvidia.png"]207748[/ATTACH] Thanks for the suggestions. Unfortunately nothing changed while testing. To continue on the testing: I've been working on this for a while yesterday with [USER=60104]@Sebastiii[/USER] and to keep it short: The issue is related to playback STOP in fullscreen mode. When i was testing windowed mode, everything was working perfectly, and on STOP I also got the HDR logo from the TV indicating that HDR mode was exited. When doing the same tests in fullscreen mode, on playback STOP I do NOT get the HDR logo popup. So somehow HDR mode isn't properly exited in fullscreen mode, and therefor showing incorrect colors. We tried a whole lot of things, including Alt + Enter to toggle between fullscreen & windowed mode, HDR toggle tools from systray, etc, but nothing solved it. In the end we noticed that when I was playing the blacklevel sample with incorrect colors, and hitting Ctrl + Shift + ESC to open Task Manager, the colors were correct as soon as Task Manager was opened. So it looks like when an overlay is opened on top of MP, the colors are correct. When closing Task Manager (to go back to MP fullscreen) the issue was present again. The only real solution is to shut down MediaPortal. So we need to look at the playback STOP for fullscreen I suppose... [b]** EDIT **[/b] Btw: It would be nice if others who experience this issue can confirm my results. [LIST] [*]No problems with the colors when you start/stop the video in windowed mode [*]No problems with the colors when you trigger and overlay (for example Task Manager) on top of fullscreen MP.
