When you have problems with your video display,it can be
something as simple as having the brightness turned down to a
bad controller on the motherboard.If you have not done,first
learn to identify the components of the video display system.
When you look inside any open computer,see if you can locate the
Video Card.Is your video card mounted in an adapter slot or is
it integrated onto the motherboard.If the card is motherboard
integrated,locate the jumpers that will allow the card to be
disabled should you need to install another card.
The Monitor is the second component in the video display and it
must be compatible with your video card.Be sure the maximumn
resolution of your video card and monitor are the same.Its even
better to your a higher resolution display on your monitor.
Go to http://www.ultimatepcrepair.com/photos.html to see a video
card in an adapter slot and one that is motherboard mounted.
Follow these procedures to correct any type of video display
malfunction.
NOTHING ON THE MONITOR
As we first mentioned,chack the brightness and contrast buttons
on the 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 the monitor
is receiving power.If the power indicator light is out,remove
the power cable and look for any bent or broken pins or
connectors.
Try to reboot the computer one or two times to be sure the
system did not just lock up.If nothing happens,replace the cable
with a known good cable to prove that the wall outlet or surge
protector has power.
If the monitor has power but nothing is on the screen, check the
data cable going into the rear of the computer. Be sure the
cable is secure.If it is,Turn the power off to the system
unit,remove the cable and look for broken, loose,or bent pins.
Finally,if you're blessed enough to have two computers, exchange
the monitor with a good monitor to see if it works.Replace the
old monitor if the new monitor works. If the new monitor fail as
well,remove the system cover to inspect the Video Card.
MONITOR WORKS BUT NO DISPLAY
When the Monitor is known to be good but its screen is still
blank,the Video Card is the most likely culprit.First inspect
the card to be sure it is fullly seated in its slot if it is
adapter slot mounted.
Check the jumpers of any motherboard mounted card to be sure a
jumper has not been lost or loose.If you have been inside your
system,its always a possibility to have moved the card.
MONITOR WORKS BUT POOR DISPLAY
If your monitor works but the images appear fuzzy,or flickering
often,and the text are hard to read,it may be time to adjust the
video card's resolution and the refresh rate.
Right click the desktop,select properties and open the display
properties dialog box.Choose the tab for settings and adjust the
slider to change your display resolution.Most 17-inch monitors
will have a resolution of 800 x 600 but choose the best
resolution for your eyes.
After adjusting the resolution,check the display to see if all
flickering and other problems have vanished. If not,optimize the
refresh rate.The refresh rate is the rate in which the video
card redraws the screen.Lower refresh rates sometimes cause
flickering.
To adjust this rate,open the display properties dialog box in
the desktop, and choose the settings tab once again.Click the
advanced button and choose the adapter tab if your operating
system is Windows 98.
If you have Windows XP,choose the Monitor tab.And from there you
can set the refresh rate to about 70Hz or 70 Hertz.Check your
monitor's manual or web site to see the maximum refresh rate for
your monitor.
To effectively maintain your video display,visit the supporting
web sites for updated software patches and device drivers.Watch
for new control software for your card that will greatly boost
its performance.
Take the time to clean the system unit case which will allow air
to flow freely.This in turn will help keep the video components
cool which will allow the card the perform smoothly.
Rush over to www.ultimatepcrepair.com/photos.html and study the
video components.Then open your PC ,locate the video card,and
know if it is motherboard mounted or not.To learn much more in
great detail, get the PC Super Pack with detailed video all
