Yeah, it's probably just setup wrong, X (the video) probably has the wrong settings, or something else (like missing nvidia drivers) didn't get setup correctly. Post your /etc/X11/xorg.conf and /var/log/Xorg.0.log files if you can. Obviously, you might have to copy them to a USB drive and to a working machine first. Rarely, this can happen because a specialized mouse or other hardware is detected incorrectly, but 99% of the time it's an error in the monitor or video card sections. If you're like most people, you've lost your monitor/video card user manual, but you should still be able to google a copy from your manufacturer or another site, and if it's built in the last decade, it's likely a seller/reseller will list the specs somewhere.
Problems like these are showstoppers for newbies, but the fix probably isn't that difficult for someone who has been around Linux for a while. Almost always a one line edit in the xorg.conf file. Another option is to try another distribution and see if it detects your hardware better, such as Ubuntu or other more "newbie friendly" distros. (SuSE's not bad, but it's geared more towards the corporate user, whereas Ubuntu and others are designed for users just getting into Linux or computers in general.)
Any details about your system might be helpful too.
