UHD Graphics 750 changes resolution when monitor sleeps

kroll

Hello All,

I have a problem with UHD Graphics 750 (on MSI Z590 Pro Wifi).

When the monitor is turned off (after e.g. 10 min, by Power Setting) I can hear the "USB/Device change sound". It goes back and forth (pairs of sounds 3 seconds apart - "plugged"/"unplugged") every ~20-40 or so seconds.

Why I think it's a graphics problem? - After "unplugged" sound, when I moved mouse to wake up monitor, the screen resolution was incorrect (black bars at top/bottom of the screen, illegible font, etc).

I have Intel Graphics Command Center installed. More details below.

 

How it can be fixed?

Thank you in advance for your assistance!

Hello kroll

Thank you for your response.


In order to review this further, could you please provide us with the following information?

1- Is this a new system? Did the computer work fine before or are you experiencing this issue since the first day that you have the device?

2- If this worked fine before at any moment, were there any recent hardware or software changes that might relate to the point when the issue started? (For instance, Windows, driver, BIOS, or software updates?)

3- We understand that you are using DisplayPort* (DP) at both ends. Do you mean you are using a straight-through connection DP-to-DP with a single cable to connect the PC and the monitor? (Not using video adapters, dongles, HUBs, receivers, etc?). Also, have you tested with different cables? Please provide details.

4- Have you tested with another monitor (using a straight-through connection)? And/or have you tested the monitor with another computer? Is the behavior the same?

5- Does the behavior occur every single time that the PC goes to sleep? Is it reproducible 100% of the time or is it random?

6- Does the monitor have a built-in USB HUB? If yes, do you have USB devices connected to it?


7- Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system:

  • Download the Intel® SSU and save the application on your computer
  • Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
  • To save your scan, click Next and click Save.
  • Once you have saved the file (.txt file), please attach it to your reply.

To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.

I use display port on both ends.

Everything works fine, but the PC goes "crazy" when the monitor is put to sleep.

Andrew,

Apologies for a slow response - I was traveling, but I'm back now.

It seems that there are a few follow-ups I need to perform. Let me try to take care of these later this week.

 

Thanks,

P.

Andrew,

That's a very comprehensive set of checks/questions you listed... and that helped to solve this issue!

I had used DP cable (DP on both ends), but I did not have another cable like this for testing, so I switched to DP to (DVI with DVI-DP adapter). Changing the cable fixed the problem! 🙂

There were no indications that there could be something wrong with the cable, but changing it solved that issue.

 

I have used the new cable for the last 2 days, and it all works great. Case closed.

 

Thank you for your assistance!

Peter
