how to adjust picture quality

If you click System --> Preferences --> Screen Resolution, do you see an option to change to 1600x1200?

  Thanks for replying Alan. I see no option to change
to 1600x1200. Also i wanted to tell you that the only
linux that works on my computer is ubuntu. I've tried
suse 10.1 and mandriva 7.0 . I installed them on my
computer and when they boot for the first time, i get
an error message "out of range" which i think has
something to do with my graphics card. It's an xfx
gt7900. My resolution on windows is 1600x1200.

Maybe you've not 1600x1200 in the xorg.conf file. Try to un from a shell
$ sudo dpkg-reconfigure xserver-xorg
and about on the end you'll see some resoltion type. Check what you want and then
$ sudo /etc/init.d/gdm restart
And try again what Alan Pope said.

Or you can just manually edit /etc/X11/xorg.conf and add "1600x1200" to your resolutions, it should be fairly straighforward and removes the need for you to reconfigure your whole system.
