Thank you TCL/ROKU; I hope others find this post useful, ever since the release of the new Xbox anyone with a tcl 4k 60hz tv would get signal loss black screens when attempting to stream (as I posted previously) with whatever was in the new update released today this was finally fixed and I know the console is not broken now.. long 30 days but such a relief!! If anyone sees this post having this issue check your firmware! —fellow gamer Shawn
