Question: is the oled worth it?
Answer: OLED isn't a good value if you're looking for a really big TV. OLED TVs currently top out at 77 inches (that should increase to 88 inches by the end of 2019), but the price increase of a 77-inch OLED over a 65-inch OLED is substantial—whereas more affordable 75-inch LCD TVs are widely available.
