Turn off the monitor and the computer.
Unplug all cables and wires that are connected to the monitor. Also unplug any cables between the monitor and computer.
Check the cables for damage and replace if necessary. Reconnect the cables to monitor and make sure they are firmly connected.

Use a different monitor to connect to the computer to ensure that the issue is not the monitor or the computer.
