Video Problems - No Video
No video, poor video
or erratic video:
- For Windows systems,
you should check the screen resolution and refresh rate (to do this in a
no-video situation, you will have to connect a working monitor to the
system).
- Control Panel
- The Screen
Resolution is generally shown on the left side, center of the window. It can be changed by sliding the arrow left or right in the box.
- Compare the
resolution with the supported resolutions in the monitor
specifications (on this site, see Products, select by monitor size,
select monitor model number, scroll down to Resolution
specifications).
- Note that LCD
monitors have an optimum screen resolution.
- They will not
display a resolution higher than the specified resolution.
- They will
display lower resolutions, but the video quality will be diminished.
- Also, check the
Refresh rate.
- Click the
Advanced button on the Settings tab.
- Select the
Monitor tab.
- The Screen
refresh rate should be displayed at about the middle of he Window. Other refresh rates can be selected by clicking the arrow at the
right of the drop-down box.
- Compare the
refresh rate with
the Hz part of the resolution specifications. Use the drop-down box
under the Screen refresh rate to try other refresh rates.
- If these settings
do not correct the problem, and if power and cable connections are OK,
then the monitor is probably defective.
