I'm running Windows 10. My graphics adapter is an integrated Intel HD Graphics 630 chip. My monitor is an Acer XR342CK. The monitor is connected via DisplayPort.
I frequently experience the following:
- I walk away from my desk for a few minutes (doesn't matter if I lock the computer or not)
- The computer does not go to sleep. I have it set to never sleep, and I'll frequently have long-running processes going, so I know it's not sleeping.
- After a few minutes, the monitor turns off to save power.
- When I come back, I move the mouse or tap the keyboard to wake the monitor back up.
- The monitor doesn't wake back up, even though the computer is definitely still running.
- I have to turn the monitor off and then back on to get a signal.
- All my windows have been resized to 800x600, and I have to go resize them all.
I have tried the following to resolve it:
- Updating the graphics adapter drivers (most recent are already installed).
- Updating the monitor drivers (most recent are already installed).
- Checking the physical connection of the DisplayPort cable (it's fine).
- Selecting a different input with the monitor, then going back to DisplayPort (doesn't work, it'll just tell me there's no signal on DisplayPort and I have to turn the monitor off and back on to get it to work).
- Using other connection types (not possible, can't drive this monitor at the proper resolution without DisplayPort, unless I'm mistaken).
As a workaround, I decided to set my monitor to only turn off after 2 hours. However, I'm now running into another issue - despite being clearly set to turn off after 2 hours, it'll frequently turn off when I've been away from my desk for only a few minutes.
Does anybody have suggestions for resolving this? I've done a lot of Googling about it, but almost everything I can find is related to monitors not turning back on when the PC comes out of sleep, which isn't specifically my issue, and the proposed solutions are mostly what I've already tried anyway.
