Contrast ratio is arguably the fundamental basis for good picture quality. OLED is currently the best due to the ability to produce absolute black; this is best appreciated in a dark-ish room. People who watch in rooms with lots of window may be better served by bright LED/LCDs. However, OLEDs also have wide viewing angles, which means there's less need to sit in the "sweet spot" to get a decent picture. I've been waiting for OLED (or its replacement technology) to come down a bit more before I upgrade from my 1080p Panasonic plasma. Those perfect blacks are truly breathtaking when watching dark content like outer space scenes...
Baby steps for me, hence the miniLED TCL I linked. It's affordable and is being compared to much pricier OLEDs as far as IQ/true blacks etc are concerned.
It lacks 2.1, but I don't need it yet anyway.
IF I buy it I'll post impressions. The only thing I'm concerned about is TCL's panel lottery. From what I've read, odds for the consumer aren't quite as high as pricier sets, but that when you do score a good panel, it's pretty amazing.
I got an amazing TCL tv before they were a serious contender. It’s still running solid as our bedroom screen.
I want my dual layer LCDs
LG has a new "QNED" set in the works...a mini-LED..
