Solved! YouTube 4k not working, only shows 1080p on Vizio 4k tv

My M55-c2 only displays 1080p even system information says Resolution: 1080p Can't watch YouTube or anything in 4k

Your devices must be 4K capable, u should have the Internet bandwidth to do so, and youtube should detect this automatically, if it doesn't, it maybe sensing part of your system can't do 4K. Youtube 4K requires 60 mbit bandwidth minimum, per user.
