I know this is a very first world problem, but it is annoying none the less.
The issue is that using xrandr I cannot go above 120 hz refresh rate, I have tested on multiple kernels with the same graphics driver and 4.17 does give me 240hz, however 4.19 nor 4.18 produce the desired result.
I would like to get this working on 4.19 zen kernel if possible.(windows does produce 240hz) I have attempted using crtc 0 1 2 3 4 & 5. all resulting in crtc x (0) failure. even adding a new mode with cvt and cvt -r results in, crtc 0 failure when set to that mode

I am uncertain as to what the cause of this issue is, as the drivers did not cause any issue under previous kernel versions, and reverting to the binaries breaks the drivers.
note that it was also tested on a different install of arch linux on a usb hard drive produced the same issue and reading the arch wiki for xorg and xrandr didn't help me much
here is output of a custom resolution attempt:

This may be a limit set in your graphics driver. I believe I remember some patches to limit the refresh rate and resolution to fit in the transfer rate of your chosen display connection. Maybe that is buggy?
Edit: I may be mistaken, though.

So then should I change the drivers ? I don't remember seeing anything about that the resolution of the display is the standard 1920x1080
also that shouldn't be the case as when I was on linux 4.17 with the same drivers the issue wasn't there.
Edit: this dosen't cover the case in 4.18 or 4.19 which is what is puzzling me and what is just not working.

The amdgpu driver is part of the kernel. What I remembered is this. It was only about HDMI connections, though and fixed in 4.19.

https://github.com/torvalds/linux/commi … c3ea4e1585
Maybe DisplayPort has similar issues that a high color depth will limit the refresh rate for a certain resolution?
I think DisplayPort 1.2 would break in your case, but DisplayPort 1.3 should still work. (I have no idea if this is really the case, I just played with the numbers a bit)
https://en.wikipedia.org/wiki/DisplayPo … ncy_limits
1920x1080@240Hz@8bpc needs 14.00 GBit/s
1920x1080@240Hz@10bpc needs 14.00/8*10 = 17.5 GBit/s
DisplayPort 1.2 has only 17.28 Gbit/s, though.

Should have also mentioned my display is only 8 bpc
Edit: so then is the solution to compile the linux kernel with the parameter that was added due to the report? that seems a bit excessive, or recompile just the module in charge of amdgpu

Not an answer to haloshrioe's question but - and that was a problem in my case - I've put the HDMI cable into an incorrect HDMI input in my monitor? I have ViewSonic XG2530, and it has two HDMI ports - input 1 is HDMI 2.0 and input 2 is apparently HDMI 1.2, limited to 144 Hz only.

Please pay attention to the dates and don't necrobump a year old topic, haloshrioe hasn't been here since either.
