Crushed colours SA750D

Hey guys.

Just signed up as i have a really annoying problem with my 27" SA750D I recently aquired.

Displayport doesnt display certain shades of dark colours correctly, but HDMI does...With lighter scenes i do not notice any problems. The media doesnt matter either. Films produce the same effect.

Have a look at these two images. Ive had to take a picture as the problem doesnt screenshot.
Ignore the colour difference. Note the washed out floor and walls etc in the first pic. First is Displayport, the other HDMI.





Ive wiped and installed drivers to no avail. Also tried many other things bar a complete reinstall...Currently on a 7970 with cat 12.7 betas, have also tried the 12.6's. Connected to the monitor via minidp to dp adapter, to dp cable into the monitor.

Any ideas? Wrong colour space? As i said it didnt screenshot, so 3d specific?

Everything is up to date. Ive also installed the monitor drivers for both hdmi and displayport. Changing the colour settings doesnt help.

I too thought it could be the cable. But, the monitor runs 120hz perfectly fine. I would have thought if the cable was at fault, being a digital signal, it wouldn't result in just crushed colours? maybe im wrong.

Something ive noticed. When hdmi is connected, in windows color management, the Samsung Natural color pro 1.0 ICM is loaded. But when displayport is connected this doesnt happen. Profiles associated with this device is empty.

Another example:
DP

HDMI

Yeah... didn't update. So for reference...

Its a problem with AMD's drivers. If I change any settings under my digital flat panels, it causes the problem. So I leave them at default values.
