Hi all.

This is my first post here; if I'm doing something wrong please let me know.

Trying to get high refresh rate to work on my new laptop; which has perfect 240hz on Windows.
The specs are for my Razer Blade 15 2022:

i7-12800H
16 GB Ram
RTX 3070ti
Two 1TB SSDs (1 Windows, 1 Linux)


I currently tried POP, Ubuntu, Zorin and Manjaro. Everything seems to be working in the respective distro once I install on the machine, but I cannot enable high refresh rate on the display. I've tried this via xrandr, and also via the GUI.

I'm currently at a loss.

Interestingly, there is one single instance in which high refresh rate did work, but only via live booting.

ZorinOS has a live boot that for some reason enables the 240hz. Once I install it however, where I choose Proprietary drivers or not during the installation process, the computer either:

a) fails to boot, and I have to go to recovery mode and manually install nvidia drivers, or

b) boots up and functions normally with the nvidia drivers pre-installed by the OS however with the inability to enable high refresh rate.

I went one further by installing ZorinOS with just the open source drivers, to see if I could enable high refresh rate (by replicating the live boot USB's environment- i.e, avoiding nvidia drivers) and it would not let me select 240hz.

In certain distros, the 240hz selection is preselected but does nothing; in others it doesn't even show up in the menu.

Any help would be greatly appreciated.

Thank you!

I have the same issue on my Blade 15 2022 RTX 3060 240Hz QHD display. I have Ubuntu 20.04 and upgraded kernel to 5.17 manually to fix some other driver issues. xrandr does not recognize any high refresh options.

Hi rook21 & welcome to LQ.

The first thing I'd check is /var/log/Xorg.0.log which should have details on how the video set itself up. There are numerous possible bottlenecks but you seem to have a good machine there. I would set up 240Hz interlaced (lines 1,3.5 followed by lines 2,4,6 on the next pass). So 240Hz = 120fps and dream on if you think you'll notice the difference. Xorg.0.log can be hidden in other places, btw.

I don't track gaming gear, so I don't know what to expect. The other thing to watch is that no distro will be set up for such a machine. Stop swapping distros. Install the one you like best, fix that up in every detail for your machine (which may take time) and then back it up.

Follow up on this:

I found that kernel 6.0.0 made the system detect the 240Hz mode. With the latest nvidia driver (version 515.76) supporting kernel 6.0.0+, everything works like a charm and 240Hz is buttery smooth!
