Every time it is applied with any of the 3 above, its applied top to middle and not centered. As soon as i change the Aspect ratio setting in AMD - it readjusts, but thats just torture.

I don't think its an AMD issue because when i change the resolution from the Adapter settings (List All modes) - it's also not centered. The only place that applies it alway's centered is from System - Display settings.

Is there anything to try? Ideally, i want centered all the time.

What monitor and what AMD GPU? Are you using GPU scaling? The aspect ratio setting should only apply to GPU-scaled resolutions. Otherwise the monitor should be in control of the scaling.

AOC Q27G3XMN. 78000XT Nitro (running DP 1.4). GPU Scaling is disabled.

I went back to my old Win 11 install (23H2) and i cannot replicate the same behavior there. Its only happening on 24H2 (with the same AMD drivers).

The monitor should tell you what resolution it's receiving somewhere in the OSD. If the monitor shows the native resolution when the problem is happening, then it's an AMD driver bug because it's not centering correctly, and it's supposed to send 2560x1080 to the monitor if GPU scaling is disabled unless it's using a refresh rate that you haven't added to 2560x1080. If the monitor shows 2560x1080, then the monitor is not centering correctly. Either way, you might have better luck with GPU scaling and using this instead: https://www.monitortests.com/forum/Threa...Editor-SRE

I tried SRE and had the same result. Then I wondered if I would got the same behavior on HDMI and I did not! Surprisingly it was always perfectly centered.

Then I switched back to DP, and now it's centered all the time. That is very bizarre behavior! It's almost like a reminder from HDMI is needed to center the resolution and then apply that to DP.

Is that even a thing? Dodgy

Question: If i get a vega56 , do you think that in Linux i'll be able to use Interlaced resolutions with the newest drivers? i wanna play the new games but i wanna use interlaced.

I wouldn't know. I haven't used Linux in a long time, but Linux drivers tend to support interlaced better than Windows.

AMD's driver is known to have bugs with GPU scaling not being centered sometimes, especially with integer scaling, but I haven't seen a monitor do this.

And is there a way to get interlaced to work on Windows with Vega 56/64 on latest drivers over HDMI??? i just want the compatibility of the new drivers but i NEED interlaced resolutions.

Does it not work with the latest drivers? I don't have a Vega 56/64 to test, but it's GCN, so it should support interlaced with HDMI. Keep in mind AMD isn't really updating the drivers for GCN GPUs as frequently as newer GPUs.

I am not sure, right now im on my i3 9100 iGPU running my CRT Monitor with an HDMI to VGA adapter, it does 1920x1200i 90hz perfectly , i am looking to buy a dedicated gpu and i need interlaced and i would prefer to avoid gpu passthrough, i am between the choice of a Vega 56, Vega 64, Radeon VII or GTX 1070/1080 , i want to play cyberpunk with interlaced scan, cyberpunk needs the latest drivers, i have been reading online a bunch of contradicting anecdotes between may and today...a lot of users say interlaced is super broken on windows on Vega on the latest drivers, some say that in some 2023 drivers interlacing works on nvidia, some people say interlacing never worked at all on Vega and VII.

I feel like im going insane and i just wish someone who had these gpus could test it in real time and give me one certain answer for good.
