Monitor going black for a few second, then resuming

I have had a few cases in the last few days of the monitor going black for a few seconds, then recovering.
There are no events in the Event Viewer to indicate any problems and the computer itself remains on without any issues.
I am not sure if this is a Windows 11 24H2 problem, Computer Problem (a 3 month old computer), or it is likely to be a monitor problem.

I did have a similar issue with the same monitor on my old Windows 10 Computer, but there were always Events logged in the event viewer saying that a driver had stopped and was restarted successfully. No such Events logged on Windows 11.
All the drivers are up to date (according to Device Manager).

I guess this is going to be difficult to pinpoint, but wondered if anyone could point me in the right direction.
There seem to be lots of examples of this happening, but no conclusive solutions - other than trying different monitor, changing cable, stabilising power supply, etc etc.

Motherboard is ASUS TUF GAMING Z790-PLUS WIFI LGA1700 ATX Motherboard (DDR5)
Computer is Intel 14th Gen Core i9 14900 24C/32T 65W 32MB Raptor Lake CPU
Monitor is ASUS ProArt Display PA248QV 24.1" WUXGA Monitor, connected by Display Port.

I have just lowered the refresh rate to 60hz from 75hz to see if that makes a difference.

I take it - you're using the integrated GPU (from above intel CPU). Device Manager - doesn't check for drivers any more (for quite some time now). The latest driver was released on 7 march 2025 (pretty sure you're not using that one).

Neves,

Yes I am using integrated GPU from the intel CPU. My Windows 10 Computer was using a separate GPU.
I wonder if it is the same problem, but because it is integrated GPU, it is not reporting the Driver Event like the Windows 10 did?

I guess it is not a CPU problem, but either a driver issue or a monitor problem.
I am going to see if the problem occurs again over the next few days with the reduced refresh rate, then I might try using HDMI instead of Display Port.
My last attempt will be to try an old monitor that I still have - if it happens on that then I know its not the monitor.

p.s.

Actually, just realised what you said, in that Device Manager does not check for drivers anymore. Perhaps I will load the latest driver as you suggest.

OK,

Just used the link you gave and installed the latest graphics drivers. Looks like it has a pretty fancy interface and control panel when I go into Device Manager and look at the Monitor driver.
Will see how it goes.
Thanks very much for your help.

When was it doing this, specifically? Meaning what are you doing when it happens, or doesn’t it matter?

Thanks for the reply. Not exactly sure what I was doing at the time - not gaming, just using File Explorer I think. Nothing that would be straining the CPU. If it happens again with the latest driver, I will make a note of exactly what I was doing.

I was just curious if it was while you were using a web browser only, this is usually caused by a browsers hardware acceleration setting.

Actually, might have been browsing the web (Microsoft Edge) as well as File Explorer. Maybe I will have a look at the hardware acceleration setting. Don't know enough about this yet to know what it should be set to though. I don't need speed, just reliability.
Would that have given an Event error in Event Viewer though, if it was due to this?

Microsoft Edge:

1. Click the "3 dots" menu icon in the upper right of the browser window
2. Click on "Settings" then "System" on the left side.
3. Toggle on "Use hardware acceleration when available" if this is not enabled.
4. Close and restart the browser for the change to take effect.
   • You can also copy and paste this link edge://settings/system into the address bar. This will bring you right to the system settings.

Just checked the settings as above. Use hardware acceleration when available is already enabled.
Thanks though.

Yes, if it’s only happening in Edge, disable Hardware Acceleration. Sorry I should of made that clear.

However, MC, it’s best to try one suggestion at a time, so if it stops, you’ll know what stopped it.
See how you go with the new Intel Driver.

Even more so, see if it’s happening outside of using a browser. If so, it’s not Hardware Acceleration in Edge.

If not the driver, or if it’s happening outside of Edge, it could be other things, like a cable etc.

Thanks for the suggestions. Yes, I will try one thing at once - firstly see how it goes with the new driver.
If it happens again, I'll make a note of exactly what I was doing and see if there are any events in the Event Viewer.
I am hoping the latest driver has fixed this.
Curious to me though that in the 3 months I have had this Windows 11 Computer the fault did not happen until a few days ago and has happened 3 times so far - (before I installed the new driver).

Could of been a recent update if not the other stuff.

Sinto,

Curious you mentioned that, because 3 days ago, I successfully installed the latest Windows 11 24H2 Update (KB5052093).
This may be entirely coincidental, but I have so far had two big issues with Windows 11 24H2 updates (one now fixed and one not).
Be interesting to hear if anyone else has monitor issues with this latest release.

MC, it’s very possible.
