We gave ourselves an LG 55" OLED 4K for Christmas, replacing a 50" Samsung LED which was perfectly fine, but what the hell! The usual setup aggravation and reprogramming the universal remote, but all is good. For good measure, bought a new soundbar and wireless subwoofer. The whole setup is outstanding! Color and contrast, way less glare issue than with the LED TV. And watching live sporting events and playing my PS4, amazing!
Edit: Not a real fan of LG'S Web OS platform, yet. A bit confounding to an old fart but I'm getting there.
