Question PC stutters and lags when second display is connected.

[Solid_Snake11]

Hey all,

I recently built a new PC and upgraded to Windows 11. I have 2 displays connected to my GPU (RTX 4070 TI SUPER) and I am constantly encountering this issue where I keep hearing connected disconnected sounds from PC. After checking all the USB ports, I found out that the issue was actually with HDMI. I have tried another cable but the same issue occurs. Basically the connection/disconnection keep happening randomly and the whole PC stutters/lags for a second or two. One of my displays is connected via Displayport to a G9 Odyssey running at 5120x1440 at 240Hz and the other display is an LG C1 OLED running at 4k 120Hz. I usually use one or the other exclusively and not both at the same time. This issue occurs only when I am running on the monitor and the HDMI is connected(doesn't matter the TV is on Standby or not but it usually it is on Standby). I have searched and tried many solutions but to no avail. To solve this issue I plug out my HDMI when using my PC monitor. When using my TV display as my only screen, this issue also doesn't occur. Only when HDMI is plugged in and I am only using my Monitor. Any suggestions or ideas what could be the issue?

My PC specs:
CPU: 7800X3D
MOBO: ASROCK X670E STEEL LEGEND
GPU: RTX 4070 TI SUPER

PSU: Make, model, wattage, age, condition (original to build, new, refurbished, used)? Source?

= = = =

Look in Reliability History/Monitor and Event Viewer. Either one or both tools may be capturing some error code, warning, or informational event just before or at the times of the stutters disconnection sounds.

Reliability History/Monitor is end user friendly and the timeline format can reveal patterns.

Event Viewer:

You can also use Task Manager, Resource Monitor, and Process Explorer (Microsoft, free) to observe system performance. Use all three tools but only one tool at a time.

Objective being to discover what the system is doing or trying to do when the issues occur.

Take your time and watch carefully.

Will come back after observing.

@Ralston18 I checked Event Viewer and saw this error everytime I got the disconnection and the accompanying stutter/lag.
Metadata staging failed, result=0x80070490 for container '{7D9C1900-D61C-5C12-A2F4-29EBBB01466C}'
After searching online, I applied the fix from here
https://www.tenforums.com/windows-1...e-update-build-19044-3803-19045-3803-a-3.html
to Change Device Installation Settings to No and will keep monitoring. No idea what this has to do with HDMI and or TV being on Standby but stutters seem to be reduced from every 10 seconds to 45-50 seconds.

Nicely done!

Unfortunately many of those error codes etc. are more than cryptic to anyone other than the developers.

And I sometimes wonder about that....

My suggestion is to try the fix a couple of more times along with "dism" and "sfc /scannow".

Premise being that there may be other factors involved that were not addressed with respect to the original fix and/or other things are happening that resurrect the problem.

After reading back though I reminded myself of another thought. When there are multiple devices involved loops can be created.

What that means in some manner Device A is connected to Device B which is connected to Device C which is connected to Devivcel D which is connected to Device A. Could be any number of ways fro that to happen: network connections, video, audio, power, peripherals.

Strange things can happen as a result. Make a simple sketch of you devices and look for any sort of connection loops. Most frequently they involve audio and power. Audio loops generally result in unwanted noises, sounds, and sound distorations.

Ground loops are more on the electrical power side. Network loops tend to affect multiple devices.

You can easily find explanations about it all. Some can be very technical - just look for basic explanations.

If you find a loop, especially one that involves HDMI and or the TV, see if you can make a change to break the loop. Even if temporarily for testing purposes.

Thank you for taking the time to write!
Actually, I came to the conclusion that it was HDMI after disconnecting everything and connecting USB's, HDMI, audio one by one. I'll do the repair now and hopefully, that can help too.
