Allot of sections look alright, you have the Linux nvidia driver. Just the monitor section appears to have some funny things, like the size -> 250x184 which is like a small laptop, it should be 300x225. Here are the specs:
You can try this command as root and try using defaults during the questioning except for something you know is wrong:
Now this is just me, but I would tamper a little with some settings in here if it's the same after the system-config thing, like changing the size of the monitor and try some different default depths, my 17" CRT uses 16 at 1024x768, you might want to right click on the desktop and select "Configure your desktop" and in the "Display" section, pump up the resolution to see if it helps. You have better graphics capabilities than my old computer that uses better settings, your settings appear pretty low. If these step fail, you should look into installing the Nvidia drivers from Suse first, if they don't have, go to Nvidia's site and get the Linux drivers that end with ".run". You have to be in init 3 to install that one.
