Video and Monitor Problems

Fill out the Diagnostics Checklist as you complete these checks.

If the screen is blank

NOTE: See the monitor documentation for troubleshooting procedures.

Check the monitor power light — If the power light is off, firmly press the button to ensure that the monitor is turned on. If the power light is lit or blinking, the monitor has power. If the power light is blinking, press a key on the keyboard or move the mouse.

Check the monitor cable connection — Check the connector for bent or broken pins. (It is normal for monitor cable connectors to have missing pins.)

Test the electrical outlet — Ensure that the electrical outlet is working by testing it with another device, such as a lamp.

Swap the power cables — Swap the computer and monitor power cables to determine if the power cable is defective.

Test the video extension cable (if used) — If you are using a video extension cable and removing the cable solves the problem, the cable is defective.

Test another monitor — If another monitor is available, connect it to the computer.

Check the diagnostic lights — See Diagnostic Lights.

Check the card setting — Enter system setup and ensure that Primary Video Controller under the Integrated Devices option is set correctly. For an AGP card, set Primary Video Controller to AGP. For a PCI card, set Primary Video Controller to Auto. Exit system setup and restart the computer.

Run the Dell Diagnostics — If any tests fail, contact Dell.

If the screen is difficult to read

Check the monitor settings — See the monitor documentation for instructions on adjusting the contrast and brightness, demagnetizing (degaussing) the monitor, and running the monitor self-test.

Move the subwoofer away from the monitor — If your speaker system includes a subwoofer, ensure that the subwoofer is at least 60 cm (2 ft) away from the monitor.

Move the monitor away from external power sources — Fans, fluorescent lights, halogen lamps, and other electrical devices can cause the screen image to appear "shaky." Turn off nearby devices to check for interference.
