My display doesn’t work, even though the computer appears to work.

2Make sure the display is turned on.

3Try turning the display off and then turning it on again.

4Make sure the display’s power cord is plugged into a power outlet and into the AC power adapter. Check to see whether the outlet works by plugging another device (such as a lamp) into the outlet. (If the light on the front of the display is lighted, it is getting power. Try the next item on this procedure.)

The message “Check Cable” appears on my display.

This message appears when the video cable is not properly connected to the computer.

2Make sure the other end of analog video cable is plugged into the PC’s video port.

The message “Signal Out of Range” appears on my display.

This message appears when the input signal is beyond the display’s capability.
