When the correct screen resolution (screen area) or the right number of
colors are not available choices in display properties, settings tab, then
it is a good bet you do not have the right driver installed for your display
adapter. The display adapter in your PC is either a video card or a display
chipset on the motherboard.
If you received a CD or floppy disks with drivers along with your PC, see if
they contain a display adapter driver and install it using: control panel,
system, device manager, display adapter.
If you know what display adapter your PC has but you have no disks, use
www.google.com to track down the correct driver on the internet. You can
also check the web site, if any, of the manufacturer of your PC.
If you do not know what display adapter your PC uses, you can try this
program: Aida32 available from:
http://www.aumha.org/free.htm Or, you can
open the computer case, look at where the monitor plugs into the back of the
case and then check that location inside the case. If there is a card
there, you have a video card or if there is a cable or a link connected to
the motherboard, it is on-board graphics. Write down any information
displayed on either the card or the chipset on the motherboard. Then use
www.google.com to search for the information. Do not include all the data
you found in one search message--search on each piece individually. If you
include all the information at once, you might not get a hit.
I have found that a video card will generally have to be removed in order to
see the information. Be careful of static electricity as it can fry
components. Before touching anything in the computer case (the cord is
unplugged, right?), ground yourself to the case by touching it. Don't work
on carpeting since shuffling your feet on it can generate static electricity
after you grounded yourself. Remove the one screw that holds the card in
place and using a rocking motion (left to right and back), pull the card
straight out.
Finally, if your graphics problem is not the result of a fresh system
installation and the display was correct at some recent point, you could try
a system restore and see if that restores the correct driver. The help file
has info on system restore should you need it.
