I have a samsung 4k uhd hdr tv and a roku 4k box. when I put the 4k in hdr mode the screen looks like crap. But its all compatible with bothe the tv and the box supposedly, and I have a cinnamon cable 4k attached to that. when i downsize the roku to just 4k uhd it looks good whats the deal does anyone know.
