I have went to display and tried to change it. When I hit apply or OK it does nothing. I first noticed this problem when I installed a HP Printer onto my computer. When trying to fix to this problem I uninstalled the printer I installed and it still doesnt work.
By the way I have:
Windows XP Home Edition, Service Pack 1.
Intell Pentium III Processor with 501 MHz and 768 MB of RAM
