[QUOTE="DragonQ, post: 1176057, member: 115209"] I am not sure if this is a new issue but it's something I've certainly noticed recently. When MediaPortal changes the refresh rate automatically, to 23.976 Hz in this example case, it seems to reset video output levels to their default setting (0-255) rather than leaving them at the correct setting (16-235). Examples: - Switch to 23.976 Hz manually - Start MediaPortal and watch 1080p/24 video - Video output levels are correct - Switch to 50 Hz manually - Start MediaPortal and watch 1080p/24 video - MediaPortal automatically switches the display to 23.976 Hz - Video output levels are incorrect - black crush is immediately obvious Has anyone else seen this happen? It's 100% reproducible for me and I wonder if the way the MediaPortal switches refresh rates is at fault. I've attached logs of the second example above where the video levels are incorrect.
