Question 34" Ultrawide Monitor keeps stuttering :(

[TitanMaster]

Hello, I have not found anyone with this specific problem:

My 34" Ultrawide monitor keeps stuttering every like 5 seconds for half a second. This issue only came about when I got my first ultrawide monitor, never happened before. It only happens specifically during gaming, not while doing any other task, watching videos/movies, listening to music, etc. It started when I got a used alienware monitor, since then I have gotten: new speakers, used rx 7900 gre, new Asus 34" monitor. However, these stutters have been happening since I first connected the ultrawide monitor. I thought it was my gpu, but the monitor stutters with both my rx 6700 xt (first owner) and rx 7900 gre (used). Then I thought it was the monitor, so I bought my current main monitor, tried it with both gpu's but it still stutters. I am at a complete loss here, I read in an article that Ultrawide monitos from 34" - 39" do this (not sure how true it is), so I was going to swap the ultra-wide for a Gigabyte GS32QC 32" QHD for main display in hopes of avoiding the stuttering by having a 16:9 display.

My current main monitor: ASUS TUF VG34VQL3A 34" 2K QHD 180Hz (have it at 165Hz & is VA Panel)
My old main monitor: Alienware AW3420DW 34" 2k WQHD 120Hz (had it at 120Hz & VA Panel)
My secondary monitor: AOC C27G2 G2 Series 27" LED FHD 165Hz (had it at 165Hz & VA Panel)
Here is the PC Part Picker link since I included literally every hardware I have to have the most information: PC Part List

Things I have tried:

• Playing with every monitor and gpu variation I could
• Playing with only ultrawide monitor on (tried both) and both gpus
• Used amd utility clean software and reinstalled fresh amd adrenaline for both gpus
• Enabled and disabled HDR
• Used Freesync Premium and set it choose settings, and also manually tweaked with settings specifically capping frames and setting target frames
• Changed amd adrenaline profile to be standard, quality, and hypr-rx
• OC'd both ultra-wide monitors while gaming
• Checked Windows for updates
• Checked display driver & audio drivers to updates
• Gamed on secondary 27" monitor (Ultrawide still connected)

I have never had an issue like this before happened to my PC until I got an ultrawide monitor. Updated Mobo BIOS about a year ago, do not know what version it is on tbh. I am trying to avoid a clean Windows reinstall since I do not know how to and am scared to wipe stuff from my PC since I do not have any extra storage to backup stuff to.

Could be system ram / vram and pagefile related, how full is the ssd? Might need to clear some space if too full so pagefile can be allowed to grow without sacrificing drive performance.

Check cpu temp and frequency while gaming.

just connecting to a different display can't cause a hardware issue like what you're seeing to prevail through the system even after changing said hardware.

the only thing that could be a side effect of that particular display would be Windows Update, or you, installing drivers for that particular display and those drivers causing some sort of software issue within the OS.

Things I have tried...

have you tried switching cables to a known functioning set?
there could be an issue with data being delivered to the displays through a common cable that may result in this sort of skipping frames.

trying to avoid a clean Windows reinstall

you could attempt to find any particular driver and uninstall/remove it.
or just do a fresh OS install.

a fresh install is not as big of an issue as you appear to make it sound.
you can very easily backup all of your personal data(personal files, OS & application settings, save games & game settings, etc) and reintroduce it to the new install afterwards.
if you've got cash around to buy new GPUs & displays on a whim, then you can definitely afford another drive(whether internal SATA, external USB, or whatever) to backup data to.

I was going to swap the ultra-wide for a Gigabyte GS32QC 32" QHD for main display in hopes of avoiding the stuttering by having a 16:9 display.

isn't your current 27" a 16:9 display?
if that was going to solve your problem then it already would have.

read in an article that Ultrawide monitos from 34" - 39" do this (not sure how true it is)

definitely not true.
i've been through 2 different myself and have known very many others with them through the years that have never experienced a similar issue.
also have never seen this as a common issue through support forums.

May or may not help you with your issue. We just got a new monitor as well and it was doing just like yours. Never had issue with old HDMI cable to old monitor but when we got the new monitor my son was on top of things as he ordered me two HDMI cords and one display port cord.

Both my sons have 34 in wide screens and are up on the cabling issues and the pros and cons.

The latest monitor was for me 27in 165 Hz and I was getting the glitches. Opened the box same as the link above and installed the new HDMI cable and life is good again. YMMV

Just like JohnBonhamsGhost said.
