4 Dell™ P793 Color Monitor Quick Setup Guide
No Image Is Displayed on the Monitor
If the monitor power indicator is on but no image appears on the display, perform the following checks:
• Ensure that the video connector is seated properly. Tighten the connector screws securely with your fingers.
•
Ensure that the computer is on.
• Increase brightness and contrast controls.
•
Turn off the monitor and unplug the signal cable. Check the cable connector for bent or broken pins.
• With the signal cable still disconnected, turn on the monitor. If the monitor is working correctly, a self-test pattern
appears.
• Perform a monitor reset or recall.
Two Fine Horizontal Lines are Visible on the Screen
The 2 very faint thin lines across the screen are normal. They are caused by the aperture grille stabilization filaments
which are required for all aperture grille CRTs.
IMPORTANT!
Before contacting Dell for technical assistance, refer to the Troubleshooting section in the User's Guide on
your monitor CD. This section contains detailed information for resolving most monitor problems.
