Hey Guys... GREAT NEWS 
... I hope that I do not jinx myself in saying this but I think my problems have gone away thanks to all your help 
.. So basically the first thing I did was as @Warner360 suggested.. I turned off Fullscreen Exclusive mode and it has not given me any black screen at all .. I have played around for approx 1 hr in and out of multiple 1080p then 4K then back to 1080p movies.. upscaling is working fine and no black screens or system hang.. Obviously time will show but it has never been as stable as now with the new settings etc and 4K etc.. so all good I also enabled force fullscreen exit on end on playback stop (I can't remember exactly what this option is called) but I enable that too.
By the way DXVA copyback doesn't seem to be working for me anymore.. its rendering times are around 60-100 so it's all choppy.. I think this is because my desktop is run at 4K resolution thats probably why.. so I just use D3D11 Automatic (Native) which works a treat..
All I need to know for sure now is whats the best option to leave the Desktop in ?
1 - RGB FULL 4:4:4 which only allows me 8 bit as desktop but when playing movies it says 12bit in the JVC info menu,
2 - YcBcR 4:2:2 or 4:2:0 which both allow me 8, 10 and 12 bit and in the JVC info they display only as YUV
there is also other options like RGB Limited and YcBcR 4:4:4
Too many options to choose from.. Just want to know the purest one and the one with the least conversion ... Thanks and would appreciate if you could help.. Thank you.
