Unfortuntely this is a commercial VPS and I can't run any command to modify its settings.
This would have been the "cleanest" way to do that but I've found a different way by adding a virtual monitor.
Thank you

Both entries related to that in cru are 80-240(detailed res, extension blocks) but the actual range is 64-240 when tested in nvidia pendulum. Any changes I make have no effect at all. CRU detects 2 samsung monitors but i make all the changes to the active one. Should I do it on both?
You only need to edit the active monitor entry. NVIDIA does not support default extension blocks and will ignore all changes if a default extension block exists. You need to delete the default extension block, add a DisplayID 1.3 extension block, and add 2560x1440 @ 240 Hz in there. Then editing the range limits should work. If not, try editing the CTA-861 extension block and add a FreeSync data block with the range you want.
I made all the changes but it's not working. Did I make any mistakes?

I don't see anything wrong. What GPU do you have?

I have a 1660ti. Could this happen because lfc kicks in at 64 fps instead of the 80 that the default setting is? Would reinstalling the drivers or trying an older version make any difference?

If LFC were kicking in, lower frame rates should be smooth regardless of the range. I don't see a way to check what range the driver is using with NVIDIA. How are you verifying the range with the demo?

The monitor has a Hz counter. Anything above 64 fps and the Hz is 1:1. When i set min/max to 64 or lower it doubles.

I'm not sure how NVIDIA handles the lower end of the range. With my monitor I see LFC kicking in even when the frame rate is still within the default range. Maybe the driver has some internal overrides for certain monitors.

I've found posts about people that managed to edit the range but they are not recent. Maybe they did change something

Edit: I tried an older driver version and cru is working. The default is indeed 80-240 and by setting it to 41-240, I got 51-240 in the demo. I guess I'll have to find the most recent one that allows me to modify the range.
Thank you a lot for your help
Hey there,
recently I installed windows 10 and moved from windows 7!
so I decided to improve my refresh rate as i did it in windows 7, but I did it in windows 10 and nothing changes!
what is the problem ?
working fine on windows 7 but not on windows 10 ... ?!?!
my refresh rate stuck at 59.973

You need to be more specific. What exactly are you doing? What is the resolution and timing parameters you're trying to use? What monitor and GPU do you have? What cable?
