I have a DELL Optiplex 7080 Tower PC running on windows 10 pro, and a Samsung SR35 Monitor. I plugged them into a 1200VA Offline UPS, but sometimes, when computer boots up (after the splash screen disappears), the monitor shuts down automatically and the PC remains on. After that I reconnect the power cable of the monitor to the UPS and now the monitor gets power! It works fine!
The problem sometimes happends when there is no power outage.

How to fix this problem?

Cause might be the power chord then that runs from your monitor to your UPS. You might not notice it, but sometimes if you move the table around and the chord yanks slightly and becomes loose either on the UPS side or Monitor side, re plugging will fix it.
