When I bought the LG OLED TV, I had been researching them for over a year. I looked at non-LG manufacturers as well. But LG had the best reviews. I have other LG products in my home that I am happy with and that may have influenced my decision as well. I considered the smaller model but convinced myself that this was my Christmas present for 2018. I purchased the 65 inch model.
The colors are bright, vivid, and very well presented. If you haven't yet, watch the built in demonstration videos. I always start there when showing off OLEDs picture punch and motion handling. I follow that up with the AVATAR movie on BluRay (not 4K), I need to buy a 4K player. Friends are blown away by the visuals in the movie.
If Golf is on, I finish up with having friends count the blades of grass during a close up of the green.
I have yet to run 4K content on the TV but, I am researching the best 4K BluRay player to purchase. My birthday is coming up, maybe I can update my review after I have spent some time watching some 4K titles.
