So I recently ditched the 46" Samsung LED for a Asus VG248QE to use as my main gaming screen but even that looks horrid with PC RGB. I just can't see any benefits to using it. No adjustments helped.
I wish Microsoft would put back in the YCBCR 709/601 options like Xbox 360 had, I used to use 701 on a few games since it looked better for them.
These are the settings i use on the Asus:
Splendid= Theater Mode
Sharpness= 40 (eliminates some minor fringing on text also use ClearType)
Brightness= 54 (according to preferences and lighting)
Contrast= 43 (default contrast in this preset gives major shade crushing)
Color Temp= User Mode
Red= 100
Green= 95
Blue= 93
If your blacks are crushed i guess you should set your console to Limited.
