Hi Guys!
It's 2022 and nearly 2023, i know this is rather an odd timing for replying *Giggles*, but i recently bought a new UWQHD monitor (cb342cksmiiphzx) and had the same problem pairing it up with a1070ti Gigabyte Aorus.
- I thought it was an issue with the DP (Monitor at first, secondly the GPU), i have swap different version of DP cables and, retested different HDMI as well but to no avail.
- I thought it was the GPU DP port that was having the issues since i bought it off from the used market (which i wasn't aware as i was strictly gaming on a single monitor through the HDMI all while using the card after purchased)
- I thought something in the GPU PCB had an issue causing this sort of glitchy artifact thing ( thats what happened to 2080 RTX for its infamous artifacting IC/VRAM issue, but i hold on this thought and proceed the troubleshooting)
- After reading a while (including gigabyte 1070ti's hardware specification), i nearly gave up and wanted to say that either my GPU or Monitor had defects and seriously wanted to pack the monitor back into its box for RMA (just in case its the monitor, as this is the fastest to get support out of the 2 options)
Yes, tuning down towards 60 fps was fine on lower resolution, the glitches were gone but since my 34inch had a native 3440x1440, i was keen to know why when im pushing higher resolution it gives me this flickering even with 60 FPS. At the time i was looking for answers through internet browser, then i realized the flickering had gone, and i switched back to desktop, and there it is again, the flickering came back!
At this moment it hits me and i concluded this is actually an issue with software integration aside to my initial thought of having hardware issues. So as always, started with playing around custom resolutions in Nvidia control panel, playing with the refresh rate and resolutions but nada, same output as what were found earlier; lower Hz,lower res its okay, higher res, higher Hz,brings back the glitchy flickers.
It was super confusing at first & then little Einstein kicked me in the head;
"Why dont you try out a higher resolution background wallpaper since Youtube decided to adaptively loads a 2K video automatically based on your native display?"
*BOOM!*
That was the answer!
My previous wallpaper was meant for my previous 27 inch 1080p (now a 2nd monitor) with the correct 1920x1080 format, and luckily i had previously saved a high resolution Maplestory wallpaper in the past with 5120x2880 resolution, i immediately switch them out to test it and voila! No more flickering!
It was really a tiring findings but it's all worth it.
Zero hardware issues found (GPU,Ports,Monitor,etc.) and was actually an issue with the native display not being able to correctly adjust between UWQHD display and a 1080p FHD wallpaper to fit in all those spaces when you switch out/upgraded the monitor around (not sure where exactly the problem lies, but probably how WinOS are currently coded on retaining the same screen settings without considering the hardware change causing an obvious malfunction).
I vaguely remembers back then though, that if a certain picture doesn't actually resembles the monitor's hardware capability, the background image turned into a solid color instead, that was probably one of the windows XP/NT/98 good genuine-way of alerting & notifying the users (my apology if this wrong).
I really hope this will be the answer for most of us who had experienced this and to those who are going to make research and stumble upon this thread to find a solution to their frustration and distressed in correlation to this glitch flickering happening to them.
Until then,
Happy New Year 2023!
