[QUOTE="HomeY, post: 1281593, member: 68365"] I think I have a similar issue, which I've been battling with for a long long time. I have a 1050Ti in my HTPC and also use it with madVR. As far as I've been able to conclude, it has to do with HDR not being properly disabled after playback of a HDR video file is stopped. I sometimes end up with a very very bright UI, but most of the times it looks normal, but the blacklevels are messed up. When I play a blacklevel testclip (attached), i can't see the reference black (17-25). Often toggling Windows HDR on and off again fixes the issues. Playing files in MPC-HC + madVR always works perfectly, hence my idea it also has todo with MP code. [B]** EDIT **[/B] I think you want to feed madVR with a 0-255 RGB input, I have my LAV Video RGB Ouput levels set to PC (0-255) but that's not gonna solve the HDR issue 2nd thing i see in your settings is that you probably want to remove the 2160p25 output setting from madVR config, since that will trigger HDR on shows like (for example) The Grand Tour. Till 25fps, HDR will be toggled, but those shows don't have HDR. something to keep in mind, you might not have had issues with it (yet) ;) Oh, and another thing: get latest Nvidia drivers (from 7/1) since there is a HDR blacklevel fix in there ;) [/QUOTE]
