finally got the connection right this time ... had to connect directly my xbox to the sony tv for the xbox settings to recognize that my tv is 4k hdr capable .. kasi sa una the xbox was hooked up to the onkyo avr (capable of 4k upscaling) - kaya pala yun xbox didnt recognize the tv as 4k...buti na lang napansin ko info sa xbox settings which says connecting thru an avr will have that result.. kaya lang i have to use optical connection between my tv and avr for the audio , otherwise, sa tv speaker output na sound.. ok naman..
and for video - just stick to CINEMA .. thats it .. wala na tweaks ginawa sa ibang settings
