Good morning.Im getting a strange problem with my Asus 7850 CUII its connected with HDMI ti my monitor an LG 3D DM2752D-PZ when im watching movies and theres a dark scene the monitor goes completely black but its not turned off if it pops something like subtitles(white colour) it goes on again.Im from a fresh windows 8 Pro install and im using the catalyst 12.10

Called LG and they said its a graphic card problem one of the settings.After searching for a while i found out that the only way not to do that is by switching back to YCbCr 4.4.4 Pixel format,if i change to any other mode it starts doing this again and only when im watching movies everything else is perfect.Is there any solution to change back to Full RGB colour?

Thank you.

If YCbCr works and RGB doesn't, then why not use YCbCr?

Unless you have a $1000+ professionally calibrated color monitor with >100% Adobe spectrum coverage, you'll never notice the difference.

Thank you very much black_zion

Funny thing now i installed 12.11 when i change it to YCbCR 4:4:4 and push apply it goes back to RGB 4:4:4 Format PC Standard.I cant save my choice.

Also on 3D games that support HD3D when i activate it my monitor goes blank saying that resolution is not supported.

Also getting random flashes from time to time.
