New Samsung 4K with Direct TV. Received error message that HDMI cable would not work.
After much work, calling service and trying everything I found the answer.
Removed HDMI cable from HDMI1 and placed it in HDMI 2 jack on TV. Problem solved. I think this may have something to do with 4K protection associated with the HDMI 1 jack.
I'm no expert just a novice but found a solution and thought I would post this in the hope of helping others.
