Ok, so my setup is the following:
Radeon HD6870 - HDMI cable - Benq XL2410t.

I for some odd reason can not disable the "GPU scaling" option in the Catalyst control center.
And yes, I have googled, but this is what happens when ever I try to disable it:

(Scenario)
1. Open CCC
2. Go to Properties (Digital flat panel)
3. Uncheck the "Enable GPU scaling"
4. Press "Apply" and...

...Voilá, it's back.

Why does it not stay disabled?

Problem solved, needed to be connected via DVI (dual link or something like that).
Works correctly now.
