When you have problems with your video display,it can be something as simple as having
brightness turned down to a bad controller on
motherboard.If you have not done,first learn to identify
components of
video display system.When you look inside any open computer,see if you can locate
Video Card.Is your video card mounted in an adapter slot or is it integrated onto
motherboard.If
card is motherboard integrated,locate
jumpers that will allow
card to be disabled should you need to install another card.
The Monitor is
second component in
video display and it must be compatible with your video card.Be sure
maximumn resolution of your video card and monitor are
same.Its even better to your a higher resolution display on your monitor.

NOTHING ON THE MONITOR
As we first mentioned,chack
brightness and contrast buttons on
monitor to be sure they are not turned down. Yea,we know.This sounds a little silly to think this could be overlokked,but believe me,it really does.
And while we're talking about simple checks,be sure
monitor is receiving power.If
power indicator light is out,remove
power cable and look for any bent or broken pins or connectors.
Try to reboot
computer one or two times to be sure
system did not just lock up.If nothing happens,replace
cable with a known good cable to prove that
wall outlet or surge protector has power.
If
monitor has power but nothing is on
screen, check
data cable going into
rear of
computer. Be sure
cable is secure.If it is,Turn
power off to
system unit,remove
cable and look for broken, loose,or bent pins.
Finally,if you're blessed enough to have two computers, exchange
monitor with a good monitor to see if it works.Replace
old monitor if
new monitor works. If
new monitor fail as well,remove
system cover to inspect
Video Card.
MONITOR WORKS BUT NO DISPLAY
When
Monitor is known to be good but its screen is still blank,the Video Card is
most likely culprit.First inspect
card to be sure it is fullly seated in its slot if it is adapter slot mounted.
