Second Display Not Waking Up

[RJP Williams]

I have two monitors, a Samsung S24E390 and an older S24F350, I've attached them to the GeForce rtx 4060 supplied with my new PC Specialist machine with Windows 11 installed. On startup the two monitors are detected and everything works well, however when the computer goes to sleep and then comes back on the primary monitor works fine but the secondary stays dormant. If I go to the 'Detect another display' it reports 'no display detected' and then sometimes takes several clicks of the Detect button to get the second monitor to appear. Occasionally the second monitor goes off without warning, again several clicks of the Detect button brings it back. Also, a few times, the second monitor has gone off and then returned with a lower resolution. I've swapped the leads around, HDMI to display port, I've swapped the monitors around. It is a new machine so there are no rollbacks on the drivers.

As I had no problems with these two monitors on my old Windows 10 machine, I assume that it is somewhere in the Windows 11 or Graphics card.

Just so that I understand your fault process:

Monitor 1 - Port 1
Monitor 2 - Port 2
Monitor 2 fault

Monitor 1 - Port 2
Monitor 2 - Port 1
Monitor 1 fault

Monitor 1 - Cable 1
Monitor 2 - Cable 2
Monitor 2 fault

Monitor 1 - Cable 2
Monitor 2 - Cable 2
Monitor 2 fault

If that thinking is correct, it would seem to me that the monitor is at fault as you have ruled out everything else?

When you swapped over the connections, did you also swap over the primary and secondary screens? Have you tried monitor 2 as the primary screen?
