Installed my Sony 65X90H yesterday and spent some time tinkering with it. 4K content looks amazing (Blu Ray, You Tube, Netflix, Amazon Prime etc). I somehow think that Netflix from Tv native app looks much better & also can do Dolby Vision. My Nvidia Shield and AVT is older versions so cant do Dolby vision. Digital content from NAS looks great for 4K and nice for 1080p but dependent on the file. Custom mode with medium settings for most features was best for me. Dolby Vision bright for Netflix DV content.
Anything below 1080p is a problem and the upscaling is just ok but not enjoyable.
Somehow Hotstar & Sony Liv streaming doesn't look great. I guess their signal is too compressed (especially live news) because i have a 100 mbps broadband and Netflix / Amazon on same connection using Nvidia Shield looks amazing. So got to be these 2 streaming services issue. Don't have cable tv so cant know if that's better.
Gaming is great in HDR but will know more after getting the X Box Series X in early next year, which is why I bought this Tv for HDMI 2.1
So if you are looking for great upscaling I think the Sony X95G from 2019 should be better as many members and reviews have pointed out. Also there seems to be slight issue of banding in some content other than 4K, so again maybe an upscaling issue. I had read it in a review and so maybe my brain is searching for it !!
Overall for 135K its a good TV set in 65 inches. Movies was not my focus as I watch them on a projector so I didn't go the OLED route, also not sure how well they upscale content below 1080p.
Thanks to all the members who gave advice, shared pricing etc before this purchase. So thought of sharing the initial ownership review.
