During Super Bowl, msg on screen said 4K available on ch 1498.
Pressed OK, msg on screen said I need to switch video format to 2160p.
I switched it to 2160p and got this msg:
"Unable to change to selected video format.
It may not be supported on this TV or can not be changed at this time."
I have a 4K tv (Visio model M65-E0)
How do I enable 4K?
