New Lenovo legion 5 pro, external screen blinking black.

[Tommy10]

Hello.

Yesterday i finally recived my new laptop, a Lenovo legion 5 pro, with a 3070 GPU etc.

But, when i have it connected to my Samsung Odyssey C27G54TQ, and set to 144hz, the screen keep flickering black.

it might happen up to 5 times every 10 second, and the whole screen sometime stay black for 2-3 seconds. 

My current fix, is to set the screen to 120hz, insted of 144hz. 

Does anyone know of any fix that makes it possible to use the screen on 144hz?

Edit: the moment i posted this, it started happening on 120hz aswell. no matter what programs im running.

 

Thanks
