OLED vs larger LCD
I am buying a TV for an 18 foot wall. I previously had a 65" LCD TV, and felt it should be larger. I could not go larger because my wife would not allow it. She is now my ex-wife, took my TV, and my money so now budget is tight enough a 77 inch OLED is out of the question.
I've been pricing out 65 inch OLEDs, but can get a Vizio E75-F for much cheaper, a Vizio P75-F for about the same price, or a Samsung 82 inch NU8000 for a little more.
The room has lots of natural light, but I rarely watch TV before the sun sets and usually I am the only person in the room. Wide viewing angles and brightness might be nice for when lots of people come over, but this happens very rarely.
