Windows 10: Why is 3/4 of my screen black on 144Hz.

Hello everyone. Since I installed Windows 11, I have the problem you see in the image with my screen. Its only the display screen, as if i want to open an app that is behind the black part, i can, as it still works fine. I think i narrow it down to a drivers problem, but i am not sure, because when i uninstall the driver and let the system install it again, the problem is not immediately solved, but it takes some minutes. I have an AMD Ryzen 7 4800H and a NVIDIA GeForce GTX 1660 Ti. The problem comes back the next day when i open the laptop. To mention, when i sleep i unplug it. Also the probl

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.
