Quick panic post. My Xbox One was fine yesterday. Today, after enabling HDR, nothing on screen:

No Signal
HDMI 2
Check the cable connection and the input source.
I've power cycled it twice. I'm using the cable that came in the box. I have no other screen to test with right now. ideas?
I can borrow another cable tomorrow if that's useful, but I'd like to try anything I can do tonight first.
I'm really hoping this is just a settings problem and not something broken 馃憤 the console was working perfectly a few minutes before I changed that setting.
