Topic: Monitor does not wake.

[Den]

I've had a new computer made with Windows 11 installed.

Sometimes when I wake up the computer from sleep mode it does not wake the monitor.

The guy who supplied the new computer said that it sounds like a problem with the monitor or the hdmi lead but nothing has changed with either and they have never given me a problem before.

If I turn off the computer and the turn it back on the monitor works.  Any thoughts.

HDMI is a strange and unreliable beast.  I have the same issue with my TV switching to different HDMI inputs.  Sometimes it does, and sometimes it doesn't.

I don't have any further ideas, other than checking in the Power / Sleep settings of the computer and / or the monitor and see if anything might need tweaking?
