Absolutely stunning picture - bright, with really good contrast, color balance, and motion handling right out of the box. 4K videos from YouTube mesmerized me, 1080 antenna broadcasts are terrific, and it even does a respectable job handling low-resolution stuff. Much wider viewing angle and better sound than I expected, too. Interface is much more appealing and responsive than on Samsung TVs I've had in the past.
I'm really picky about picture quality but don't have an unlimited budget, so when WalMart on Black Friday had by far the best price anywhere, I ordered this online. Store pickup was smooth, too.
This set is NOT cutting-edge late 2017 technology - for example, the HDR capability is more of a pseudo-HDR, but there's precious little HDR content out there anyway, and not all of us want to sink 1-2 grand on a TV or risk buying a low-end brand.
Very happy camper here!
