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.

I'm having the same issue as well with the Optix MPG321UR-QD. After Windows sleeps the display it's completely hit or miss as to whether the MSI will wake up. Like OP, the monitor light goes white, showing a handshake is happening and then the display shows "DP no signal" and goes into standby mode with monitor light showing orange. I have to power it off and on again to get the display to come alive.

This is my only complaint with the monitor and it's infuriating as I leave my PC on all day, and this is disrupting my use of it. Whether "auto-scan" is on or off, I've replicated this issue multiple times on each setting. I have an old Samsung monitor connected alongside which wakes 100% of the time, so this is 100% an MSI issue.

Have you done a firmware update

I tried multiple different 1080 Ti's and kept having the same problem. As soon as I added a 30xx series card, all the issues vanished. Try updating the new firmware as well.

I hadn't, mainly because there were no patch notes to describe whether the new firmware addressed the problem or not, and I only had the monitor connected via DP rather than USB as I have no need for the KVM function.

Anyhow, I've now upgraded from FW.016 to FW.017 so will see how it goes and report back if it's still a problem. After pulling the power cable out post-update as instructed by the GamingOSD software, the monitor didn't detect my PC again so that's not a great sign.

I'm running a 3080 albeit with an older NVidia driver v472.12. Newer drivers have had issues with Gamestream so that's not by choice, but I can't imagine this is a problem at the graphics card level given my other monitor behaves properly.

I don't think it's necessarily the graphics card but maybe something between them both. My 1080 Ti's worked fine with my other monitors. That's a very old driver you're using. I don't think they added official support for the monitor until Dec/Jan. My setup is basically the same as yours 3080/MPG321 over DP.

Since I upgraded to FW.017 I've reproduced the same issue where the monitor does not recover after it goes to sleep. The PC tries to wake it, the monitor light goes white, can't find a signal and the monitor light goes orange and goes into standby.

I also tried routing the mouse and keyboard through the monitor KVM into the PC thinking maybe that would wake the monitor directly, but nope. When the display goes into standby the KVM stops working and you can't even wake the PC up. That makes the KVM useless. Considering this is something MSI advertise heavily I can't believe nobody tested this.

The driver is only from September last year. I think there have only been 4 new drivers since then and when NVidia release a driver they're just as likely to introduce bugs as to fix them so I try not to upgrade with every new driver. I've also never heard of a monitor that needs a graphics card driver update to work properly. It's just display port protocol which everything should be compatible with. I've also installed MSI's driver for the monitor at the OS level so the graphics card shouldn't really be involved at all beyond providing the physical connection.

Nonetheless, I've updated my NVidia driver and will see how it goes and report back if it's still broken.

And I shouldn't have to upgrade to support the display port protocol; that's absurd. I think you're confusing NVidia Optix with the band name of this monitor.

The September driver had no official support for the monitor. I see now that it was added in the late October drivers, so hopefully that will make a difference. You should always be updating your drivers since they add better support for newer games and devices. I don't think I've ever had new Nvidia drivers cause any problems, except when it comes to Gamestream. If you're still having problems, try DP. If it's none of the above, then I can't think of much else.

Thanks. I do have GSync enabled on the monitor and on the prior driver the monitor showed as unsupported in NVidia Control Panel, but on the new driver it shows as Gsync compatible. Fingers crossed that was the issue.

I've been testing this for the past week and the monitor now reliably wakes up both when Windows sleeps the screen and when the whole PC sleeps. Looks like I did need that driver update after all. I don't know that I would have tried that solution without you suggesting it, so thanks. 👍

I am having the same issues, except I have updated the MPG321UR-QD to the latest firmware and I also have the latest nVidia drivers installed.

This is clearly an issue with the MSI monitor (firmware, driver or otherwise), as none of my other monitors have this issue.

When the system reboots, the screen does not wake up from standby. When in Windows and the screen goes to sleep/standby, it does not wake up. (I'm using an RTX3080 connected to the monitor via displayport)

Can MSI please look into this issue and fix it? The monitor is not very usable if it has issues detecting an actively connected input. Unfortunately, most reviewers haven't tested this, but perhaps they should be made aware of the issue.

Yes, I have also tried different settings on the monitor including turning off auto-input detect, which has no effect on this issue.. These are features of the monitor, why should users have to turn it off?

So I've done more testing and I've narrowed down the issue. Its caused by the auto-brightness setting. Once the setting is off, the monitor has no issues waking up from sleep/standby. Haven't tested the reboot yet, but its looking better now.

Definitely needs a firmware fix.

After a week of more testing, unfortunately, still happens. Quite random though. I hope they fix this because this is really poor performance for a monitor in 2022....

I am still having this issue with the newer XBOX version of this monitor. I have tried everything above. Nothing seems to work. Anyone else figure this out?
