I got this TV yesterday after coming from a Sony w800b (2014). Wow, the 900E is very bright. Last year I tried the 850d which I thought was just terrible with washed out blacks and not being able to get bright enough for HDR content. So that went back. I then tried the 930d, which was considerably better than the 850d, but its problem seemed to be the Android TV interface. It was just slow, and painful. Also, the black seemed worse than the w800b it was replacing !! .... So that went back ;-)
So one more time .... now with the 900e, I'm happy. It got the brightness I want, but also the Android TV interface is snappy enough. Blacks are great and colors are vibrant. Looking forward to hooking up the Sony x800 UBP to this tv later !
