In my other thread, I posted about my monitor screen going black for a second, then coming back on. I thought it had resolved itself by changing the RAM speed to 3200, but the problem has persisted. The screen goes black when gaming and general PC use. It only happens once or twice during a 6+ hour period.

Here are my specs:

-Corsair RM750
-AMD R7 5800X
-Silicon Power NVMe M2 gen3x4 2280 SSD
-ID Cooling SE 214 XT ARGB Cooler
-Gigabyte Radeon RX 6800 XT
-B550 MAG Tomahawk
-G Skills DDR4 3600 8gb x2, changed to 3200, default setting is 2133. Pretty sure I had black screen problems at 2133, so I don't think this has something to do with it, though I could be misremembering.
-Asus VG27A
-Windows 11 Home

Things I have tried:

1) Changing RAM speed.
2) Ctrl + Shift + Win + B; restarting graphics driver.
3) Undervolting GPU.
4) Updating, reverting, and then updating GPU drivers.
5) Ensuring monitor drivers are up to date.
6) Changing HDMI port on monitor.
7) Changing HDMI port on GPU.
8) Changing Power Plan to Balanced.
9) Changing GPU mode between Gaming and Standard in AMD Adrenalin Software.

I think that is everything I have tried. I might be forgetting some things.
 
Have you tried each monitor on its own? Does each monitor work when only one is plugged in?
 
Hi,

Have you updated your motherboards BIOS to the latest version? Are you overclocking any components? Have you tried a different monitor to make sure its not an issue with your Asus monitor? Do you have another video card that you can test the computer with to make sure its not a video card issue?

Unfortunately, I only own one monitor. I can say I've played my Xbox Series X on it without any problems.

1. I have, yes.
2. Increased RAM speed from 2133 to 3200 mHz, although I had the screen issue at 2133 mHz.
3. I have not, but I can play Xbox on it without any problems.
4. I don't, unfortunately.
 
Do you use the same cord when connecting the Xbox to the monitor as when you connect it to your computer?

I don't; I will use that cable and report back to see if it is still creating the problem.
 
Did you run Display Driver Uninstaller and complete reinstall your graphics drivers while disconnected from the internet?
 
Is your monitor connected to a powerboard or direct to a power socket
What else is running

Can you Download and run and then post. https://www.ccleaner.com/speccy/download

whenever my graphics driver does an auto-update, the screen goes blank for a second or two.
obviously, your driver shouldn't be updating that regularly, but I wonder if it 'thinks' there has been an update of some sort and is auto-refreshing the screen each time.

otherwise, it would be really good to get your hands on another graphics card - friend, family member, work colleague, neighbour - as that would tell give you your answer straight away!

another monitor would also be helpful.
yes, the Xbox seems to not suffer the same fate.
do you run it using the Xbox as long as you would when the monitor is connected to the PC?
maybe it's the back light in the screen - again, a quick swap of monitors would eliminate this possibility real quick.

Direct into the wall outlet. My tower is plugged into the same outlet. I tried a different outlet and still experienced the same problem.

Here is my Speccy profile: Speccy
I wonder why it says my RAM is at 1600 mHz when it said 3200 mHz in the BIOS after I changed it from the default of 2133 mHz.

Yes, I've ran the Xbox for a longer period with no issues (12 hours).

I guess I could buy another monitor and graphics card and return them to Amazon once I'm done with them, but I'd like to exhaust all possibiities before going through that hassle. Unfortunately looks like I"m running out of things to try.

The screen just blacked out as I was posting this and made an audible pop as it did so.
