Hertz randomly dropping from 120Hz to 60Hz

Hello, I have had a problem for about a year now with my laptop.
My hertz randomly drop from 120Hz to 60Hz, However, the Hertz remains at 120Hz in the Nvidia Control Panel.
What I do to fix it is just changing the resolution to a lower one than switch back to 1920x1080, and that fixes it.
However, I have had enough, and I cannot keep switching it back so many times. It's completely random; in a game, or just in discord, or just writing something in Word for my university work, or just using Chrome.
The drivers are not the problem because I have tried installing the older ones with which I didn't have the problem, one day the hertz just randomly dropped and I thought it was a glitch or something, but clearly, it's become very annoying.
I already tried disabling the G-Sync, however, it didn't work.
I already tried installing older drivers, updated drivers, however, it didn't work.
I did a DxDiag, so if anyone can help me fix this, I would be very thankful.

I could gather from googling your hardware specs that you are on an EVGA SC15 laptop , I could also see that you have no presence of an Intel GPU , can you confirm if there is a mode in Bios where you can work in either Hybrid or Discreet modes for GPU ? If Evga managed to default this laptop to use Nvidia GPU all the time (Discreet) then I suggest you remove your current driver and install the desktop version of the Nvidia driver , the laptop version of the driver is designed to let the Intel take over refresh rate control , now since there is no Intel GPU present then refresh rate has no handler , which is why you need to assign it to Nvidia via Desktop driver .

If it still found to glitch then I suggest you contact the Evga forum , they are known to have a good forum .

Thank you for trying to help me, I really appreciate it. By googling, I saw that my CPU has an integrated Intel graphics card; however, I do not see an option for either Hybrid or Discreet modes for GPU in my EVGA Bios. I can't even access my GPU options, there is only CPU/Storage/Ram modifications I can do. I just installed the desktop driver for the 1060, I hope this fixes it.
I will give updates here in a few days, or hours if it works or not

I suggest you remove it via DDU while unplugged from internet then installing the Desktop version of the driver not opt for updating just to make sure you are not leaving any residuals of the laptop version of the driver .

I did what you said, and sir, I cannot thank you enough for your help. I haven't had any drops from to 60hz and everything is smooth now. Thank you!
