KDE Plasma - only 50hz - Resolution 3440x1440 with GTX 970

Hey Guys,

I've installed Arch Linux on my Desktop today. Everything works fine except the point that in my native monitor resolution i only can set 50hz instead of 60hz.

I've tried to set it manually in the xorg.conf but it didn't helped for me. Any ideas what i can do?

Wise women say: She who provides information about the graphics card manufacturer, whether HDMI or DP is used and whether nouveau or the closed nvidia driver is installed, alongside the brand and model of the screen, will more likely get an answer.

It's an Gigabyte Geforce GTX 970, HDMI Port is in use. The screen is a LG-UM 95 P

I've installed the Nvidia Driver with "pacman -S nvidia nvidia-utils" so i guess it's no nouveau driver?

The output of the nvidia-settings also shows me that the current nvidia driver 346.47 is installed

Did you generate a corresponding xorg.conf using nvidia-xconfig?

If i remember correctly, it is not needed anymore (xorg.conf is deprectated) because all settings are in /etc/X11/xorg.conf.d/ and here are the config files.

I don't think you can get 60Hz from these displays with HDMI (I have one, I tried and couldn't, and I have an AMD card). Try it with DisplayPort or Thunderbolt.

I second what MSC says, I have the same display and you cannot use it at 60Hz with HDMI.
