Windows 10: why does my monitor say it is at 144hz but on my pc its 120hz

i have had ths monitor 2 years one day it sudenly said in gmae that i only have 120hz i checked my monitor and on the monitor gui it says 144hz while on my pc it says 120hz

:)

 

My 144hz monitor is stuck at 60hz.

I've already done most of these things. I've updated my monitor drivers and my GPU drivers, I'm on the most recent Windows version. Though I should mention, that this is a hand me down from my father, who used this monitor and GPU at 120hz with an HDMI cable. The current resolution I'm running at is 1920x1080@60hz, but when I look at the "List All Modes" in advanced display properties, there is one listed for 1280x720@120hz. I did test it out by switching the resolution to 1280x720 and in the advanced display settings it did say 120hz, but I don't want to sacrifice quality for smoothness, as this monitor should support 1920x1080@144hz. I've tried using the Nvidia control panel "Create Custom Resolution" but no save option appears after I press test with 144hz selected.

 

No display signal in Windows at 144hz

Hello,



Thank you for writing to Microsoft Community Forums.



I understand that you are using a monitor that supports 144Hz, however you getting black screen after the sign in page.

As per the information provided by you, I have checked that the monitor supports 144Hz. However, the Sapphire RX 570 graphics card that you are using supports only up to 120Hz using the display ports. Please refer the graphic card
specification by clicking on
Sapphire RX 570.



I suggest you to set the refresh rate for the monitor at 120Hz and check the result.



Follow these steps to change the refresh rate of the monitor.

1. Press Windows key + I.
   This will open Settings.
   
2. Click on System.
   
3. Click on Display.
   
4. Click on Advanced display settings.
   
5. Click on Display adapter properties for Samsung monitor.
   
6. Click on Monitor tab.
   
7. Under Monitor Settings, use the drop-down menu to select the refresh rate and change it to 120Hz.
   
8. Click on Apply button.
   
9. Click on OK button.
   

Hope it helps.
