Windows 10: Windows randomly changes refresh rate from 120hz to 60hz

For the past few months my laptop has started to randomly change its display refresh from 120hz to 60hz, and in order to reset it to 120hz I need to reboot. I think this probably tied to a recent Windows update, but since this was more than 10 days ago I don't have the option to roll it back anymore.


Windows display settings doesn't have an option to change display refresh at all, so I can only access this setting though the nvidia control panel, which is set to 120hz and doesn't change its value even when Windows drops to 60hz. However, I can test on https://www.testufo.com/ that the display refresh has actually changed from 120hz to 60hz, then after I reboot it's fixed.


I've tried upgrading my graphics drivers, and when that didn't work I downgraded them but that didn't help either. Windows updates are also all installed except the most recent feature update.

Refresh rate

Hello everyone

I have bought a new laptop and it says the max refresh rate is 120hz. But whatever I do I cannot get past 60hz. I tried It with NVidia control pane and with windows display settings. But on both NVidia control panel and windows display settings (list all
modes and refresh rate) it says I cant get past 60hz and my driver is updated. I even tried to get 120hz with a lower resolution but it doesn't work. If someone knows what the problem is can you help me?

 

How to set refresh rate 60Hz on the TV when connected to HDMI?

I've connected my laptop(Windows 10) with the TV using an HDMI cable. The resolution of the laptop is 3840x2160 and the refresh rate 60Hz.

The TV's resolution is automatically set as 3840x2160 also, but the refresh rate shows 30Hz.



I cannot change the refresh rate to a higher rate, because the option is not available.




Now, when I change the resolution of the TV to 1920x1080, I'm able to change the refresh rate to 60Hz.





Why can't I put the resolution as 3840x2160 and the refresh rate at 60Hz for the TV? Does the issue have to do with the HDMI cable, or Windows?

My TV's max refresh rate is 120Hz. Supposedly I should get that option also, but it's not showing there.

 

Refresh Rate Changing Itself at Random

Hello all,

Not sure if this is actually a problem with my graphics card, my laptop's screen, or something else but hopefully someone can point me in the right direction:

As the title says, my laptop screen's refresh rate keeps changing itself from 120Hz to 60Hz seemingly at random (mid-game sometimes). When it suddenly starts running at 60Hz, both Windows display settings and the Nvidia control panel still show it's set to 120Hz and it doesn't revert back until I manually switch it to 60 and then back to 120. Turning G-SYNC off doesn't fix the problem. I'm running the latest Game-Ready drivers (441.66) and Windows version 1909 (18363.535).

I tried a clean install of the drivers after running DDU and also tried reverting back to 441.41 (with which I had no issues that I can recall) to no avail. Also clean installed Windows entirely multiple times: once I tried both manually installing all manufacturer drivers and another time I just let Windows Update do its thing and I got the same result with each so I'm at my wit's end trying to figure out what changed.

If anyone is having the same issue or can provide any suggestions, I'd really appreciate the help. Thanks! (My profile is updated with my full system specs).

Update: Quite literally just after posting this, I tried fiddling with the Nvidia control panel settings again and I changed the refresh rate to 60Hz and my screen started flickering non-stop and changing it back to 120Hz stopped the flickering but didn't actually change the refresh rate back to 120Hz as it normally always has. Rebooting still temporarily fixes the problem. I'm now thinking my screen is indeed failing though it's shown no other issues...
