Samsung 4K 65" error message About HDMI cable

[Leftyjp]

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.

Thanks for posting this information. 4k sets often have only one hdmi that works for 4k.

On my Samsungs, 4K works on the MHL or the ARC port. (input 4). That would be the best port to use.

Only worked on HDMI 3 (MHL) for me with 4K. Others worked but pic was downconverted to 1080p (which still looked pretty damn good).
