Refresh rate can't go over 120hz

Desktop Environments Plasma
1

Hi!

1 year ago it worked fine for me after installing some drivers.

now i got back to linux and it doesn’t work anymore, i’m stuck at 60 and 120hz should be up to 175hz, at the beginning of my fresh eos install it was able to go up to 175, but the monitor didn’t display anything (and was unusable, flickered really fast)?

GTX 960, 1 display 60hz, 2 display 175hz
LTS-Kernel

i looked at other threads but most of them made me think, newer versions of plasma are broke?

tried nvidia, nvidia-lts, nvidia-dkms. yes i also have the 32lib and nvidia-settings installed

i appreciate any help! :purple_heart:

I’m at 240 Hz on Plasma on my ASUS ROG Swift PG279QM, and I am happy to report that I have no trouble at all.

Whatever your problem is, it’s probably not as simple as “Plasma is broken”.

edit: that remains true after update to Framework 5.108 from 5.107.

I used inxi for the above;

Could you post your full hardware. Post the url

Is the system fully updated? What is the reason you are using the lts kernel? Have you tried first of all with hooking up only one monitor and getting it working and then hooking up the second monitor and trying.

system should be fully updated “yay -Syu”

why do i use the LTS kernel? well isn’t it more stable than the rolling release?
well i’m not an absolute beginner, but i still struggle sometimes while using Linux, so isn’t LTS more suited for me? (well it’s Arch lol)

yes i have tried booting Linux with only 1 display, but idk which driver i tested it with, which driver would be recommended?

Unrelated but the “-Syu” part is unnecessary. Just yay is fine.

There are a number of newer UEFI Bios updates for this motherboard. The latest version for 2023/6/29 is 8.01 Beta. You should update to at least the version 7.40 dated 2022/11/2

I myself don’t believe in using an lts kernel unless there is a need to. To me it defeats the purpose of using a rolling release OS.

I would at least update the UEFI Bios and start from there.

alright, i didn’t do it because my cpu came with a paper that said newer versions of the mainboard aren’t necessary since it could break stuff or some type of sh*, but i gonna look it up again and see how to install the new UEFI Bios version.

i hope i’m not mixing anything up :slight_smile:

EDIT: yes i did mix something up..
the mainboard came with a manual sayin’ which CPU are supported and which are not!

*ASRock do NOT recommend updating this BIOS if you are going to use Pinnacle, Raven or Summit Ridge CPU on your system.
*Before updating this BIOS, please also read the description in previous BIOS version.

i dont have the money neither the warranty if something should break, so i’ll refrain from doing it for now, until i know for sure it’s gonna work.. would it break the CPU or would a rollback work?

also funny, their site is saying 2.20 is not recommended.

well i’ll also gonna look this up, how often would i need to update? and how stable is it against the LTS kernel, which pro and con are there? since i don’t often need the newest stuff.

i’ll be back in some hours :sleeping:

It is not uncommon for the early point releases of new kernels to have issues. Unless there is something you need/want in a newer kernel, it is safer to use LTS for most use cases.

However, I would recommend installing both so you can easily switch if you ever have an issue with one or the other.

This is just the standard disclaimer that all motherboard manufacturers use. Updating the UEFI Bios is very easy to do using instant flash. Instructions are here.

thanks, i succesfully updated my BIOS, atm it seems absolutely fine.

i think i’m ready for the next steps?

Do you only have one monitor currently hooked up? I see DP-4 running @ 120

DP-4 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 597mm x 336mm

16

yes i did remove my display completely from the pc, because:

Monitor 1 should hav 175hz not 120hz~

17

It doesn’t look like it detects any higher refresh rate than 120. I’m not sure how you said it worked before?

Edit: Maybe you can check this section

https://wiki.archlinux.org/title/xrandr#Adding_undetected_resolutions

sorry… 170*
https://aoc.com/de/gaming/products/monitors/ag275qxl

a year ago it did after installing drivers, and few days ago when i clean installed EOS

the settings displayed above 160hz, but above, it flickered!

so i thought i install the drivers, since i also want to play games and a lot of ppl say installing drivers should be the first thing :no_mouth:… after installing the drivers everything above 120 was gone.

Well you have the Nvidia drivers installed correctly.

It is rendering from the nvidia card.

Not sure what it shows now if you have both monitors hooked up and run

@Wasting6674
Have you gone into the monitor settings on each and checked settings? Freesynce Gsync???
