Here's one they didn't tell you about: OLED is subject to burn-in. Like plasma and CRT before it,
Yes- i understand the others have the burn in issue too- but I wasn’t going to shell out a large amount of money for an oled if that problem was going to be an issue when i already have a CRT television which gets great contrast and color t any angle already- OlEDS at least had great viewing angles before- but they were more subject ot burn in a few years ago- perhaps that has changed in recent years- I don’t know-
Not sure what brand you have for LED- but like i say I’ve not found one that looks good at angles over 40 degrees- The last time i looked was around last Christmas as we were wanting something larger (can’t read the menus on smaller CRT well anymore-) But could not find one that looked good at angles- Even the LG 4 k ones that I viewed suffered from it-
