Hello everyone!

My MPG321UR-QD is having an interesting problem and I can't figure out why it's happening. When I go into the "Power and Sleep" portion of the Windows 10 settings app and set the monitor to turn off after a set number of minutes of activity, it becomes hit-or-miss on whether I can "wake" it back up again. When I wiggle the mouse or touch the keyboard, the power light turns white to signify that it's coming back up....but a lot of times the screen simply stays black and then I get a "DP - No signal" message on the screen. It then powers off (amber light). To get it back up again, I have to either turn it off and on via the power button...or it will also come back right away if I disconnect the display port cable and pop it in again. Any thoughts on why this is happening?

Is it even worth using that feature to begin with? Or is there another option when I won't be using the PC for a few hours, but don't want to do a full sleep or shutdown?

Thanks!

LOL at least your DP port works! -My Optix MPG321UR-QD never detects the DP port video output from the GPU... multiple DP 1.4 cables & DP ports on either GPU's (1080's in SLI) resolved this... still waiting for a response from MSI, in my thread here:


I was able to get it to work on HMDI @ 60Hz, but it frequently drops out to a black screen and will sometimes resume, after a a few seconds -VERY annoying to say the least.

If you aren't running any VM's, why don't you just power the PC off? -I imagine that your boot times can't be that bad (especially combined with an NVMe / SSD boot drive)

My boot times are indeed quick, as the operating system is on a solid state drive. But I'm thinking that it's better to simply leave the PC on if I'll be returning to it in only a couple of hours.

Typically I've set only the monitor to automatically go into sleep mode after 1 hour of inactivity. But for some reason, it's causing a problem with this particular monitor. Today, it successfully woke up after one sleep session....and then it failed to wake up later on after another.

1.Please refer manual on page 17 and modify "Auto Scan" to OFF.
2.Please refer manual on page 20 and modify "Power button" to Standby.
Then check it again.
After I created this topic, I tried turning off "Auto Scan" to see if it would help. It then woke up successfully a few times....but tonight, it once again refused to do so when it had been in sleep mode for an hour-and-a-half or so. I've now also set the Power button to "Standby" and I'll see if that makes a difference.

It's very odd to me that the monitor loses the display port handshake and is so hit-and-miss on retrieving it again.

I am using an MPG341CQR on a laptop and when leaving the computer for a short time, the external monitor (connected to DP) falls asleep while the internal screen is still active. Now the MSI monitor is not waking up and stays black. The computer still seems to have the monitor as active because I can move the mouse pointer out of the local screen. Only switching the monitor on and off or unplug and plug the DP cable brings the monitor back to live.

I'm experiencing the same issue. Waking it is completely inconsistent. My MPG321 won't even re-awaken in between reboots. The BIOS is never listed unless I completely power the monitor down and power it on again. I tried the steps above with AutoScan, to no avail. I have a 1080 Ti/Asus x570 and none of my other monitors have this problem with my computer. My friend also purchased a MPG321 and is experiencing the same issue. I'm glad I found this thread, clearly MSI has some answering to do.
