GPU Monitors doesn't resume from Hibernation

For years I've been setting my PC to hibernate when I've finished with it for the day.

I've got 2 screens plugged into the GPU and one off the iGPU. I also have my TV plugged into the GPU, though I don't output to that most of the time.

Occasionally when I resume from hibernation only the screen plugged into the motherboard wakes up.

I've tried hitting shift+ctrl+winkey+b to restart the graphics driver but those screens still don't come on.

This happened just now, so I hit the rest button and when windows reloaded I think had the iGPU monitor and one of the other two, this time restarting the graphics driver got all three on.

Anyone got any idea why this would be happening? I think it's only been doing it since I upgraded from an RX480 to my RX 6700 XT.

It probably happens about once a month or so, so I've just been living with it.
 
Yes to inputs.

I'll have to check the event viewer next time it happens, forgot that existed. Thanks.

I was wondering if it was perhaps a PSU issue. I have a 550W in at the moment, though I did buy a 850W ages ago but never got round to swapping them over.
 
Just happened again.

Cycling the inputs didn't work, monitors connected to the GPU says no signal.

Can't see any errors in the event viewer.

Looks like the GPU hasn't resumed from hibernation with the rest of the computer.
