Unfortunaly i have no choice. xf86-video-ati does not support my Ati 7750.

Thanks for your help, you pointed me to sometign i could investage.
So after some time here is the solution

aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0

As root, this persist between reboots, but not between driver upgrades (not tested myself
yet).

Another option can be adding this to your $HOME/.xprofile

aticonfig --set-dispattrib=dfp5,positionX:0
aticonfig --set-dispattrib=dfp5,positionY:0
aticonfig --set-dispattrib=dfp5,sizeX:1920
aticonfig --set-dispattrib=dfp5,sizeY:1080

Being dfp5 the name of your devive. also adjusting the resolution of course.
