I went from plasma to plasma and then to Fald.
I had a modern GT50 as my last plasma.
The black levels on the Xf90 when dolby vision kicks in are insane you can't tell its an lcd.
The black bars are black
Same on my Samsung in all fairness, it's the bleed from the middle of the screen that ruins it. Black bars, or a black screen then it's black. But you never got the same bleed on a plasma, and I doubt with OLED. I probably should've went fald really. But I got a good deal.
