RE: #2 I think so, just to add: pretty much every available driver I tried that was more recent than the v340, the same thing happened. So there must be something that happens for nvidia drivers 340+.

Everything works file. I upgraded my NVIDIA driver to 435 and then everything is still fine until the login screen. When I enter my password, the screen goes black. So, I connected my old HD monitor, rebooted, and it worked! Funny thing is that, when I'm logged in the OS, if I reconnect my 4K monitor, it works! But if I restart my system, the problem persists.
