@OOBIDUB Unfortunately I have an update this morning on sleep/wake - having put the system to sleep overnight and woken it this morning, my USB-C connected monitor did not wake. That's a bit annoying.
Before this morning the longest sleep I had done was about 2 hours, and that worked fine. Seems odd that 2 hours would work and 9 hours wouldn't, so probably another factor.
A second difference is that when I went to bed last night, after putting the system to sleep I turned all my monitors off at the mains. Then I turned them back on from the mains this morning, prior to waking the system. Maybe that makes some difference on the USB-C port.
I'll do some more tests and report back. I've not yet tested without WEG, and WEG hasn't been updated for these new GPUs, so it's possible it's causing some problem (as noted with others reporting no >60ghz support with WEG running.)
Update 1: Just now I left my PC for 30 mins and followed this procedure:
- Put system to sleep
- Turned monitors off at mains
- Came back 30 mins later
- Turned monitors on at mains
- Woke system up with mouse.
And all monitors connected fine, including USB-C.
Update 2: I did a further six quick sleep tests:
- Tests 1 - 3: Put system to sleep, waited 30 seconds, woke it up
- Tests 4 - 6: Put system to sleep, turned monitors off at mains, waited 30s, turned monitors on, waited 30s, woke system up
In all six tests, all four monitors connected.
So maybe it's time based, ie a long sleep causes problems where a short one does not? I don't know what the difference would be between sleeps of 2 and 9 hours, but maybe things can change after a certain period of time.
Or it could just be intermittent - like a 10% chance of it failing or something like that. But then it seems to happen every time for you?
It could also depend on the monitor, and/or on the USB-C to DP cable/adapter. This is what I'm using at the moment:
That's plugged into the USB-C port, and from there I have an 8K DP - DP cable to the monitor.
