How to stretch screen when changing resolution

Davigetto · 2010-03-10 18:27:11

Hi,

I have installed recently the catalyst 10.1 driver on my pc (previously I had xf86-video-ati). When I was playing games at 1024x768 on the former driver xf86-video-ati, the screen was stretched until it filled all the monitor. Now, with catalyst it always keeps the 1920x1080 resolution, just showing the games in fullscreen at 1024x768 with a huge black frame filling the rest of the monitor, instead of stretching it.

Is there any way I can solve this?

This is my xorg.conf:

hmm, are you sure its not the monitor that is effectively not stretching the screen? check your monitor's OSD there should be an option to disable it.

Sure. Changing to xf86-video-ati drivers makes low res apps to fill the screen entirely, as opposed as catalyst for the moment.

Ohhh, and I need the catalyst driver for my work.
