I discovered that 90% of my faults (drop outs, cutting out resolution change from 4K to 1080 and back again, blue screens etc.. ) were all down to the cable I was using..

The Ruipro cable fixed all the drop outs and blue screens I was getting after stopping playback.. That's my fault for messing around with the Amazon redmere cables I had purchased. I will be sending those back now.. The Ruipro is very good .. It detects HDR and sends the signal directly to the JVC like it should be and HDR kicks in ..

Couple of things I noticed however.. When HDR is active it automatically sets the Gamma to HDR (ST.2084) which looks stunning, however I noticed it crushes a lot of the dark and black areas.. So I experimented and changed the Gamma for HDR to B and that was a bit better for the blacks (in brought back highlights in the blacks) but the brighter scenes were not as good as when they were with (ST.2084) gamma.. Hard to explain but has anyone else experiemented with this at all? would like to know what others use for the Gamma setting with HDR content..

Also Those with HTPC.. Do you set your desktop resolution to 4K or 1080p? and what colour space are we supposed to set desktop as within the GPU? RGB Full 4:4:4 or YcBcR ? Thank you.. 

Here are some pics with Gamma at HDR (ST.2084)


and now with Gamma for HDR set to B:
