Other Screen problem.

Enable HLS to view with audio, or disable this notification

What could be wrong with the screen.

We replaced cable. That doesent help.

Works fine with another pc-screen, and also works fine if we choose our tv on the network.

Sometimes it can do this for 8-10 hours, and suddenly it works with no problems. Until next time we turn on the pc.

What's the model for the computer? Should be on a sticker on the back.

Some standard trouble shooting steps: 1. Run updates through Windows updates, and get driver updates from the manufacturers website(Lenovo, Dell, etc.)

  1. Open command prompt as administrator and run "sfc /scannow" and "dism /online /cleanup-image /restore health.

  2. Check the ports on the back of the monitor for debris and unplug/replug the monitor.
