Custom Resolution Utility (CRU)

[Dalle]

Hi there,

I've managed to add a custom resolution to my Samsung PS64E8005, 71.928Hz with bitstream enabled.

But sometimes BOTH my monitors goes completely black, completely randomly, and the only way to get around it is to do a hard reset of my PC.
When viewing dark pictures or just looking at a dark background, pixels (only on the darker areas) flash and change colors, is there some settings I can tweak to get around this?

I don't experience any of these problems when running the default 60Hz.
Attached is a screen of my current setup.

Thanks,
Victor
