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

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
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.

I have a GTX 1070. I just tested again with the latest driver, 561.09. Interlaced works with HDMI as long as the progressive version also exists. I was able to add 1920x1200i @ 90 Hz as long as I also add 1920x1200p @ 90 Hz (can be standard or detailed resolution). I don't have a CRT monitor, but my LCD monitor accepts interlaced resolutions, and it reports the correct kHz for the interlaced version in the OSD. If I don't add the progressive version, NVIDIA control panel lists the resolution, but setting it does nothing, and the interlaced refresh rate isn't listed in the Windows display settings. Maybe that's where the confusion is coming from. NVIDIA must have broken something at some point. This is with Windows 10.

I don't have a Vega 56/64 or Radeon VII, but I have an AMD Ryzen laptop with integrated Vega 8 GPU, which is also GCN 5.0. I wasn't able to get interlaced resolutions to show up at all with the latest Vega driver, 24.3.1. I don't know if this is because it's a laptop or if an older driver would work. I saw someone mention interlaced working on a Vega 56, but that was a couple of years ago.

Well this sucks, it looks like im going with a pascal gpu, i really wanted an AMD gpu because i wanted to get into linux and i was told that nvidia doesnt work well on linux.

Thank you so much for taking the time and giving me one concrete answer on the nvidia side, at least now i know for good that the latest nvidia drivers (as of 19 of September 2024) will do interlacing.

RE: Custom Resolution Utility (CRU)
My monitor (Asus XG27UCG) supports 4k at 160Hz, but it seems only when DSC is enabled even when I connect it to my RTX 3070 using HDMI 2.1 cable (Zeskit X-Tech 6.5ft). The GPU, monitor and cable should all support 48Gbps to allow 4k at 160Hz and 8bit with CVT-RBv2 and even CVT-RB timings without DSC. Nvidia CRU doesn't allow me to add or set any custom resolutions and any attempts using the ToastyX CRU have been unsuccessful. I understand that this can only be done by adding DisplayID extension block. When I disable DSC in the monitor's OSD I don't even understand how I can set the refresh rate to 144Hz over HDMI 2.1 since 120Hz is the highest one listed in the TV resolutions. Does anybody know if it's possible to create a custom resolution of 3840x2160/160Hz/8bit that I can force the monitor to use when DSC is disabled and if so exactly what settings I need to change in the ToastyX CRU to allow me to do this.

You can add it in a DisplayID extension block, as you said. 144 Hz might be in a hidden extension block that CRU doesn't support yet, but that doesn't matter since you can add it manually along with 160 Hz. NVIDIA's driver will only allow EDID overrides with DSC disabled, and the monitor might not accept 160 Hz with DSC disabled. Check the FRL rate in the HDMI 2.1 data block and make sure it's 48 Gbps.

All my testing has been with DSC disabled which the monitor allows me to do in the OSD. HDMI 2.1 max FRL rate shows as 48 Gbps. After adding 4k/160Hz in a DisplayID 1.3 extension block (with CVT-RB timing) and running restart.exe (same with rebooting the computer) the selectable max refresh rate in NVCP drops from 144Hz to 120Hz, so not only is 160Hz not being added, but the 144Hz is actually being removed. I tried adding 144Hz in the same DisplayID extension block just to test, but it's still not being added and the max shows as 120Hz.

Thank you for your help.
