75hz monitor stuck on 60hz

Hey, so im trying to set my external display to 75hz to ease my eyes just a bit more, but i cant.

i realize that its because one of my monitors (laptop integrated) is 60hz and the external is 75hz, and xserver/opengl (one or the other, im not sure) can only sync to one of them, and coincidentally its syncing to the 60hz one.

Ive tried changing the synced display in nvidia-settings but its stuck on "Auto" with no other options.

Ive also tried environmental variables like __GL_SYNC_DISPLAY_DEVICE="HDMI-1-2", messing around with the optimus-manager config for xserver, disabling the compositor, and even disabling my integrated monitor, but nothing works.

I know for a fact that it should be able to do 75hz on 1920x1080 as it could on windows, even though xrandr-prop is saying otherwise.

Thanks in advance! :smile:

Here is my xrandr -prop:

I doubt you know what this means. How fact is that? Any evidence? Are you sure WinOS would inform you about it?

Can you provide a link with the instructions for how to apply this and when?
I have read this at Archwiki. Can you try it, if you haven't already?

Multi monitor setups using different model monitors may have slightly different refresh rates. If vsync is enabled by the driver it will sync to only one of these refresh rates which can cause the appearance of screen tearing on incorrectly synced monitors. Select to sync the display device which is the primarily used monitor as others will not sync properly. This is configurable in ~/.nvidia-settings-rc as 0/XVideoSyncToDisplayID= or by installing nvidia-settings and using the graphical configuration options.

I was going to propose this, so, since this fails, I suppose you can't do much. As stated at the above article, you can sync Xorg server to one frequency (so it's possible), unless there is no possibility by HW.

Your xrandr output agrees that your 2nd monitor can go to 70 something Hz, but on specific resolutions (not HD).

Maybe it is enough for your case, or you can accept a lower resolution as a workaround.

Note: xrandr reads and uses a monitor's EDID, which is the vendor's exposed HW info and this is a Standard. All OSes read the same fact-sheet. If some OS technicians or devs are magicians, we are not all magicians... :person_shrugging:

I was able to turn up my monitor refresh rate to 75hz on windows at 1080p, otherwise there is nothing else to go by.

Im going to try that out. It wasnt available in the GUI.

I also tried this xrandr --output HDMI-1-2 --mode 1920x1080 --rate 75.00 which didnt work

I cannot set the refresh rate higher than 60hz even on those resolutions, i already tried.

What is the make and model of you second monitor?
As reported and actual are normally different.

Its a Samsung and the model is LF24T350FHRXEN

Doing 0/XVideoSyncToDisplayID=HDMI-1-2 did nothing, when i open up nvidia-settings it just overwrites it and deletes it, after rebooting still nothing happens.

It looks like you monitor is being over-drive'd to 75hz at 1080p it,s default is 60hz reading the spec,s

Oh, does that mean i wont be able to do it on linux without wizardry?

Exactly, how many times should we repeat this?

Right, sorry, no need to be angry.

Sometimes hardware manufacturers create special drivers that enable device features or improvements, but only write the drivers for Windows. :frowning_face:

It's not really a matter of being angry, so much as exasperated with this misconception. Everyone coming from the Windows world expects their hardware to operate exactly with the same features/behaviour as in Windows. Most computer hardware in the world is targeted at Windows. Linux is not something most manufacturers are concerned about. If they actually do provide drivers for Linux, they are often not as feature rich as the driver software they develop for Windows. Some manufacturers do not even provide drivers for Linux. In many cases it is only through the efforts of free software developers that reverse engineered the driver, that the hardware works in Linux at all.

It simply gets frustrating constantly dealing with Windows users who expect every piece of hardware ever produced will work exactly the same on Linux as in Windows. That is simply not the case. Linux is not Windows, (for the hundredth time).

Yes, i understand windows is not linux, and ive understood that since the time that i first switched to linux, because it was a headache, but i thought that something like a monitor should be able to behave the same.

Anyway, im going to close this thread and try to mess around with some options, thank you all for the info and help.
