My new computer monitor turns off for 40 seconds then automatically turns on for 2 minutes then off again, and the cycle continues. Moving the mouse or hitting a key does not turn it on, so I don’t think it’s in hibernation or sleep mode. Please help if you have any ideas. Thanks

    Your cords could be loose. Check all connections from the monitor to the computer and to the power outlet. If they are good, the wires might be bad. Opal

    Could be a problem with the CRT tube, try using another monitor. From saf r
