Mac HDMI output to tv produces green screen

Hi Folks

I've tried connecting Mac to my television via HDMI cable and consistently getting a green screen.

In an effort to address this issue I have:

Changed between Mac Mini (2012) and MBP 2015 - get exactly the same issue
Done a clean install on the Mac Mini
Changed the HDMI cable
Changed out the tv to brand new Hisense 65" 4k HD

I'm still getting the same issue of movies going green when on full screen and am able to replicate this across Netflix/movies on an external HD and have no idea why.

Best thing I can find from research is it's some kind of issue with handshake, but don't know how to address.

Please help!

I have the same problem with external fullscreen via HDMI. Goes green after a second or two.

But it's not consistent. It happens with NetFlix in Safari. And with QuickTime playback.

But YouTube in Safari is OK. Also NetFlix in Chrome is OK.
