I got a call back from a tier 2 support person at Hisense. Very pleasant and a clear difference to level 1.
She sent a firmware flash which I installed. Did not change. The set does 444 at 4K30 which is useless for a pc or television playback. We will see what their next step is.
I remain a skeptic. We are 6 months into 2016. This should be working on anything this new.
