Black screen after installing nvidia driver on desktop.

Hello all. I’m here to look for help.

So, I am running Debian stable and wanted to switch to Fedora, but I can’t figure out how to make the nVidia driver work. Whatever tutorial I follow, I end up with a black screen and often no video signal at all.

I have an i5-9600K and RTX 2070. And the screen is a Samsung TV.
It doesn’t work with nouveau. So I have to switch to integrated graphics, then install and configure things, and then reboot and switch to dedicated to test it. And then it doesn’t work. Yes, my card was on the list, when I did lspci in Fedora.

I pretty much ran out of tutorials. What can I do to make it work?
I will post any additional information needed. Thank you.

Here’s the Xorg log from my latest try:
(Yes, the TV is correctly connected.)
