Aaaaaaaaaahhhh. Paralysis Analysis. Great thread. I can't wait to hear what Mr. Page gets and how he likes it.
I am in the same boat. I had an LG 65" OLED 2015 model EG9600. But I got it just as HDR was coming out, such that there was an "A" and a "B" Model where the "A" model did not support HDR over HDMI. The apps on the LG did have HDR though. Anyway, as posted earlier in this thread, yes getting 1st generation tech sometimes really sucks. I like that the C9 and 77" has HDMI 2.1. But I am also liking the Sony XBR900F at 85" and I love the Samsung Q90R 82".
So much that I know I will love any of those three. That I just can't decide. And do I really need to go 82" or 85", technically I am only 10 feet from the wall (once we get our remodeling done) and my brother has a 75" Sony (few years old) in his house that looks massive even from 12". It is amazing how even just 10" difference from my 65" can look massive.
I loved OLED and how black the blacks were. But it is definitely dark, and have reflections. I never had burn in. And Epi 3 of GoT would have been more impossible to see what was happening. In our new condo, we have big sliding doors to our patio that will be near our TV. My wife never likes it to be dark in the room, so lights will be on at night watching, and the light from the doors will keep it light during the day. So I like what people have said in this thread that the Q90R is amazing at anti-reflection.
Sony has the cheapest price for me, Samsung has the anti-reflection and LG has the OLED which I prefer. I just can't decide.
Good luck to everyone.
