If you have propitiatory fglrx drivers installed, use the amd control panel. It is quite comprehensive and "generally" works right. ;)

This video will show you how to install proprietary drivers if you have not already.
Will also show you how to access control panel as root.

if you mean "catalyst control center", that resolution is not selectable - but the monitor supports it - with the old xorg system, we could add the resolution by editing xorg.conf. But, I do not know with the new system.
I have already installed the fglrx drivers.
Thanks to both of you.

This works for me - xrandr -
Code: [Select]

If you're comfortable editing xorg.conf, get the machine into text mode (issuing "init 2" as root works), log back in as root then do "Xorg -configure".
An xorg.conf.new will be placed in /root. Make needed changes, test with Xorg -config /root/xorg.conf.new. When you have it, copy it to /etc/X11/xorg.conf. Then you can go back to graphical with "init 4".

If xorg.conf is present, xorg will use it. If you have a working xorg.conf for this machine/display backed up somewhere, you can just copy it over rather than generating a default and editing.

There's also a way to put just the needed changes (and not have an xorg.conf) under xorg.conf.d, but I don't know the ins and outs of that. Maybe someone can enlighten us both.

Thanks roarde, edit Xorg and adding custom resolution did not work, but the "xrandr" method worked. Hope this helps someone else.
Greetings.
