How do I make my monitor 120 hz refresh?

I have a 120 HZ samsung 2233RZ which allows for 120 HZ refresh.
I have a newly installed 11.2. However, when I go to the dislpay properties to change the refresh, the highest value I have is 50 hz.

I looked in the etc/x11/xorg.conf. thinking I had to edit it there… but I didn’t see a value for refresh… and didn’t know the syntax if I needed To add it there.

Any ideas?

Give more details of your hardware – primarily which video card you’re using.

Which graphics card?
If nvidia, try running nvidia-settings as root to set the refresh rate.

I have a nvidia 285

When I run Nivida settting… I can see where the refresh rate says 59 hz… but I cannot update it…

Whwere can I update this?

Heres my Xorg.conf… display section
I dont have a 226BW… I have a 2233RZ… but it wasn’t a option when I did sax2… My quetion is, what do I change here to get the refresh to show at 120 hz?

the nvidiasetting show 59hz… but no place to change it.

This is just an example (not written for your monitor ) to show you how to enforce a specific refresh rate. I’ve never done it with 120Hz. I didn’t know until I read your post that LCD monitors could do that. Not sure it will work at all.

Hmmm… Where can I find the correct syntax then?
Just find someone that has 120hz working running linux and a 2233rz/

Thats the frustration with linux… In windows… It works fine… dont have to screw around… Linux it a totally different story…

The main reason linux will never own the desktop…

please_try_again has given you the correct syntax (by way of exmaple). Since that is the native resolution of your monitor, it should be ok. You can use the gtf CLI utility to generate modelines. Then copy to the ‘Mode’ section of xorg.conf.

gtf 1680 1050 120

man gtf

AFAIK, the 120Hz mode is for 3D gaming only, and dependent on some piece of NVIDIA software (3D Kit I think) which works with only two monitors currently available. Very much doubt that there’s Linux support for it. Windows doesn’t support it natively either.

On the other hand, Windows users come to Linux with their own Windows expectations.

I’m glad you didn’t wonder why Windows should not own the server. lol!

Turn off “gpu scaling” in the nvidia driver, that should fix it!
