Strangely though 1280x1024 is a standard resolution. Both my graphics card and monitor support it, but I have to specially enable 1280x960 using Radeon Tweaker to use it, and I can never get it to stay in that res on reboot, so I gave up and went for 1280x1024. The other 'wrong' one is 1800x1440, which should be either 1800x1350 or 1920x1440 for the correct aspect ratio.
