Troubleshooting Tips

Display Has No Power
If the display power indicator is off and no image appears on the display, check the following:
Ensure that the power cable is fully inserted into both the display's power port and a working electrical outlet.
Test the electrical outlet by plugging in a working electrical device, such as a lamp.
Press the power button, hold down, and wait for the power indicator to light.
Try another power cable on the display. Use the computer's power cable and turn on the display with the signal cable disconnected.
If the display is working correctly, a self-test pattern appears.
No Image Is Shown on the Display
If the display power indicator is on but no image appears on the display, check the following:
Ensure that the video connector is seated properly. Tighten the connector screws securely with your fingers.
Ensure that the computer is on.
Increase contrast and brightness controls.
Turn off the display and unplug the Color Reference Signal Cable. Check the cable connector for bent or broken parts.
With the signal cable still disconnected, turn on the display. If the display is working correctly, a self-test pattern appears.
Perform a display reset or recall.
