To the fence-sitters: This is a tv that costs as much as a jet ski, or a really expensive bicycle. I don’t jet ski, and I don’t want to ride a $7k bike. What I do want is to be one of the first people to see what photos look like in 8K. And obviously, this tv delivers. I don’t think you would be able to detect the difference in anything less than the 82” model, though.
In general: there’s no 8K sources other than your PC. My GTX 1050 doesn’t do well with 8K video. ( surprise). It does fine with static images, at 30 Hz.
My 65” LG OLED had an overall nicer picture, but I don’t think I’ll be able to afford an 82” OLED for some time.
Blacks on this TV are every bit as good as the OLED.
