[arch-general] Screen Scaling Issues
Hello, i am having some problems setting up Xorg correctly. I have a ATI Radeon 7750 codename "Cape Verde" VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cape Verde PRO [Radeon HD 7700 Series] I have a problem when i start X, on 1920x1080 the screen is not fully used, i get some black border all around the screen. To "fix" this i have to open amdcccle and in the DTV(1) section -> Adjustments and on Scalling Options i have to move the bar from 0 to zero again. This does solve the problem, but it does not persist between reboots (does not change Xorg.conf at all even as root). Is it possible to set this as an option on the xord.conf ? I probably does, but I failed to find the name of that option. As attachemnt goes my catalyst config file Any sugestions are welcomne. -- Regards Alfredo Palhares

Sounds like an underscan/overscan issue. Try xrandr --output <output name> --set underscan off

Sorry, I didn't see that you are using fglrx. I think there's a catalyst GUI or something with the overscan options. I can't help you there though because I've only ever used xf86-video-ati. Additionally, your monitor may have overscan settings.
Hello Mathew,
Sorry, I didn't see that you are using fglrx. I think there's a catalyst GUI or something with the overscan options. I can't help you there though because I've only ever used xf86-video-ati. Additionally, your monitor may have overscan settings. 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. -- Regards, Alfredo Palhares
