Bug Description

So, I installed Ubuntu 20.04 on my laptop with Ryzen 7 4800h processor and Nvidia gtx 1650 graphic card..
But i wasn't able to make my external monitor work..
At first it wasn't even recognized, but after I updated kernel to version 5.7.1 and with(only with latest) nvidia drivers 450 it recognized external monitor and I get options when I press SUPER KEY + P that I can switch screens..
But even though I pick external monitor and I see that it switch to it, monitor is turned on, but I have only black screen and can't do anything..
