Question Monitor repeatedly wakes from standby mode, how do I fix that ?

[CrimsonKnight98]

TL;DR Bolded

I've had this issue for months (maybe longer). I'm not sure when it started, but here's what happens:

My monitor will go into standby mode, after 3-7 minutes (no set amount of time) it will wake from standby, display nothing on the screen for a second (a black screen), then it will turn back off, and show DisplayPort in the top right corner before fulling going back into standby mode.
For a time after replacing my DisplayPort cable I noticed the monitor would only do this wake cycle every other time the monitor went to sleep. It's very inconsistent, sometimes now it will wake after an hour, other times it starts within a few minutes of standby mode, and sometimes it doesn't seem to wake at all.

Any help or insight would be so greatly appreciated! This has been driving me nuts for months!!

So I finally got an energy trace report and found the (potential) culprit. It appears to be the AMD display driver "amduw23g" going haywire and waking my monitor.
No idea what to do about this still. 🙁

I've tried:

• Clean booting Windows
• Booting into Safe mode
• Running Windows update
• Updating BIOS (was running latest BIOS already)
• Updating drivers as listed on ASUS' website
• Running an Energy Trace which showed my GPU was causing the system to wake up (energy trace link: https://drive.google.com/file/d/1JNVVLei1l_jLvuIv3-AAu6Pfad14eShp/view?usp=sharing)
• Newer Energy Trace (after all the troubleshooting): https://drive.google.com/file/d/1jCZrvXoKXb2NIsvQJly1T5zyqdq8iNy2/view?usp=sharing
• Installing latest GPU Drivers
• Clean uninstalling GPU Drivers using Display Driver Uninstaller and reinstalling fresh
• Clean uninstalling and then flashing OLD display drivers from 2022
• Switching DisplayPort cables (twice); first new one was DisplayPort 1.2, most recent is 2.1 and VESA Certified (so no potential of pin 20 issue).
• Switching to integrated GPU (problem goes away)
• Removing and reseating GPU
• CMD sfc /scannow (errors found and repaired; ran multiple times to be sure)

Because you switch to integrated and it works fine, I think your GPU is the issue.
It's an issue in the sense that, the GPU is causing the inconsistencies you're mentioning, but it still functions as normal.

This happened to me when I had a Gigabyte 3070Ti.

When I put the computer to sleep on the LATEST driver, it would wake up almost soon after I put it to sleep but also would not let me use the PC as it would black screen until force restart.

Restoring the driver back to the factory defaults (from the Manufacturer's website) made this problem go away entirely. Updated the driver from NVIDIA, back to square one.

I'm now on a 3080 and can put my PC to sleep and wake it up with no issues. The screen will not suddenly turn on when I least expect it whilst it's asleep (although, this can also be a process in the background causing it to wake up)

My assumption at this point would most likely be the GPU causing it.

Sadly restoring to any previous driver doesn't change this behavior.
The only thing now is it seems completely random.

Sometimes it happens, sometimes it doesn't. And it appears to jot happen specifically when I initiate an energy trace in command prompt.

I might be able to try this in a different system, but that would take me an immense amount of time. 🙁

Yeah, unfortunately without testing it in another system to definitely rule out the likes of the GPU being an issue, it's difficult to say really.

When you say any Driver, it needs to be the very first driver for that card (released by manufacturer)

Drivers want to be current.
Uninstall the driver software that does such checking.

 

[CrimsonKnight98]

Okay I tried the default drivers and it made my system completely unstable. Like every driver was failing, I don't even know how to explain what all happened.

I did make a discovery though, when I run an energy trace through command prompt (powercfg /energy /trace /d C:\Users\Me\Desktop /duration 600) the issue stops. I have tested this over a dozen times. It will not wake the monitor at all during or after the test, but it will go right back to fluctuating if I manually resume the system and don't run an energy trace.

Any ideas?

So I finally caught an energy trace and found the culprit. It appears to be the AMD display driver "amduw23g" going haywire and waking my monitor.

You can see in the Power>Device Dstate section, there are a lot of D3 signals from this driver.
This appears very randomly too. I can't always get this behavior to repeat and it was a miracle for me to capture it on a energy trace.

I will state again I have tried clean installing new drivers and many old, this behavior is consistent all the way to the very first driver.

Any ideas?

Is there an option in the amd driver install to select/omit checking for driver updates?
Something like nvidia experience.

If so, opt out.
Plan on updating the driver when you need to yourself.

I think the AMD Software Utility will notify me if I choose to install it but I only installed the driver itself.

Again I tested tons of driver versions. Each one (after clean installing them with DDU) has this issue for me.

I found that the GPU RADEON light will randomly turn on and off too when the monitor is on standby... does that provide any other clues?
