Just a quick update - you were spot on about DVDFab's version changes. I tried a few different v5 builds and none of them would activate HDR. Switched back down to v3 and HDR comes on flawlessly. So v3 it will have to be

After playing around with a few settings, I can confirm that HDR is working for me in the latest version 5 software. It actually plays smoother for me than with Powerdvd 18, where I get an occasional stutter. Still am unable to make it work with Kodi however as an external player (at least with Leia)

 We understand many players and methods will play UHD HDR titles without actually engaging HDR mode.  Given PDVD v.18 and FAB v.5 are both performing UHD HDR for you and switching HDR mode on, evidently you meet the minimum requirements (at least for PDVD or it wouldn't be working).  Perhaps this is the key to get FAB v.5 working?  Please share which Intel SGX CPU, SGX motherboard, and Intel HD Graphics you are using.  Thanks.
