Refresh rate on AMD rx 7900 xtx


I'm new to Garuda and also new to using an AMD GPU having always used Nvidia with proprietary drivers in the past.

I have just installed Garuda on my system with a new AMD rx 7900 xtx and under display and monitor settings the highest refresh rate I'm offered is 60Hz at 3840x2160. Previously in both Ubuntu and Fedora with the same system and screen other than Nvidia GPU I had 120Hz or 119 point something I think on the same screen, a 55" LG TV. I see in the output below it seems to think the screen is 72" instead of the actual 55" but I believe this was the same in Ubuntu and Fedora with Nvidia too.

Is there an AMD equivalant to the Nvidia-settings application that I need to use? Or some other way of getting 120Hz at 4k on this screen?

Any help would be greatly appreciated thanks.

Hi there, welcome to the community

First of all, TV refresh rate might be different, even though they are both 4K TV from Same brand. They might be very different. Most of the times 4k TV do not offer 120Hz refresh rate, but more expensive TV do.

Secondly and more importantly, there might be a difference at HDMI cable, or you might be using display port instead of HDMI in your other configuration.

4K at 120Hz is only supported in HDMI 2.1, while HDMI 2.0 support 4k at 60 Hz only.

These are the first things to check.


Hi, thanks for the response and the welcome.

It is the same exact TV I was using in 120Hz at 4k with an Nvidia rtx 3080 and the same HDMI cable too. Using a single cable from HDMI on the GPU to HDMI on the television in each case. No adapter or display port.

Hi, yeah, I searched on internet, and check this guide

Also see the first comment, users on other distributions with different monitors are facing similar issue.
I have no experience with AMD dGPU, so can't help much there. But I guess this is more or less AMD GPU related problem. Most probably, it will be fixed with time. You can report this bug at

It is most probably due to your GPU being too new and high end, in my humble opinion.

But don't worry, it will be fixed before too long, most probably


Thanks for that, I did wonder if perhaps it was just too new a card but also thought maybe it could have been my lack of experience with AMD. Thank you for your help and your time.
