Acer XB270H A is 144hz but stuck at 60hz

[osqup]

I moved my setup to another location and before that my monitor was running perfectly at 144hz but after i moved my setup it shows only 60hz. The monitor was moved safely and didnt take any hits or damage. So i dont know what to do i tried changing from nvidia control panel but only available option was 60 hz.

UPDATE:
Got it work on 100hz one time. I made a custom resolution 1920x1080 with 80 hz and it worked, and then it told me that i can go up to 100hz and i did, But few days later im at 60hz again! And it allowes me to make a 144hz custom resolution but still showing 60hz and after i click save it says it saved but in reality it didnt.

No driver changes after the move? Possible a setting in the monitor's OSD needs reset since it was disconnected from utility power?

 

[osqup]

Nope, no driver changes. And resetting OSD does nothing :/I,ve re-installed my gpu drivers but nothing happened. And now when i start up my pc it says no signal. So i have to shut off the power when Windows is loading so it will get error next time i start it up and then i have to change start settings so it will start with lower resolution.

Strange. I'd re-seat all the cards and cables at this point. Checked for OS corruption? Seems unlikely but worth a shot.

Part of the problem may be what cable you are using to connect to it, and what graphics card you have.
1080p 120Hz is known to work on DVI, but not on standard HDMI. If you haven't already, try connecting with DVI (if you can).

Which connection are you using? Remember with that monitor only DisplayPort can achieve 144hz. Also try disabling G-Sync just to see if that's causing issues.

You can circumvent the Nvidia custom resolutions and make your own using Custom Resolution Utility (CRU). It's a free program.

I can only use DP cable because its only cable that goes to my monitor. And im using GTX 1060 3gb but i tried using gtx 780 but i got the same problem.

And what you mean with OS corruption? Where can i check if there is OS corruption?

 

[1LiquidPC]

An sfc/scannow in elevated command prompt. This will scan the OS for file integrity.

 

[osqup]

Yeah but i mean how can i check if there is corruption?

 

[1LiquidPC]

The scan itself will notify you if there are integrity violations. If it finds any, it attempts to repair.
