This resolution is not supported. Please change your external resolution.

So, I recently build my own PC which I hooked up to my TV through a HDMI Cable. When I start my PC, it boots, it starts to load Windows 10 and then my screen goes black and the screen says "This resolution is not supported. Please change your external resolution." (Which is a rough translation but it gets the point across) So, I tested the resolution's the TV could handle through my laptop going from 800x600 to 1920x1080 and it showed up just fine, so I have no idea what I did wrong. I have been trying to solve the issue for 2 days now and decided I just couldn't do this on my own. Could somebody please help me out?

So..... Whats your current build bro? If you dont have a GC then your Onboard Graphics may not support 1080p

Never mind, it supports up to 2k resolution. Have you checked the cable inputting into the onboard graphics?

The cable inputting into the onboard graphics? I thought that was standard in the processor?
