Basic Checks:
• Run the monitor self-test as instructed in the monitor user's guide.
• Connect the monitor power cable directly to an electrical outlet to
ensure that the monitor turns on. Do not connect it to a power
protection device, UPS, power strip, or extension cord.
• Ensure that the monitor power cable is firmly connected, verifying
that the power cable is adequately connected at the monitor and to
the electrical outlet.
• Swap the power cables between the computer and the monitor to see
whether the problem symptoms change.

hibernate, state. Push and release the power button, move the mouse,
or press a key on the keyboard to bring the computer out of the
suspended state.

the cable connector for bent or broken pins. Check for damaged or
frayed cables.

connected to the computer.
• Adjust brightness and contrast settings on the monitor.
If the problem still exists after you complete the basic checks, fill out the
