LEARNING TO USE THE MACHINEI AM AN OLDER CRITTER THAT IS TRYING TO LEARN TO USE A MODERN PIECE OF TECH THAT IS MOST LIKELY SMARTER THAN I AM. I AM LEARNING TO USE MY NEW TV SLOWLY AND COULD ONLY WISH FOR A PRINTED MANUAL LIKE THE ONE I USED WHEN LEARNING TO HERD DINASOURS WAY BACK WHEN BUT LIFE GOES ON AND I AM ENJOYING MY NEW TV JUST FINE.

Amazing picture!With amazing clarity, brightness, and true blacks, this TV is a BEAST! This is the center piece to my home entertainment center and has become even more of a favorite than my beloved sound system. LG TVS are so intuitive that I bought another one for my bedroom!
The remote is easy to use to with a cursor feature that takes some getting used to, but pays off by adding ease to entering passwords. Simple set up, except for the base, right out of the box.
Over all- great TV at a reasonable price. Love it!

Ok, it really does make a difference!I've been happy with my 10-year-old LED TV. I knew technology has advanced, but really, how much better does TV need to be? I had an opportunity to buy a new TV for a second home, so went with what I understood to be the best. I have to say, with the right source material, the picture blows me away! I guess I'm going to have to replace the old LED in my other home!

There is a version of this TV sold at Costco. Is the only difference between this TV (OLED55C9PUA) and the Costco one (OLED55CXAUA.AUS) is that the Costco model has a α9 Gen 3 AI processor 4K instead of a Gen 2 processor? Do you offer a Gen 3 unit here?
Asked by: melrowgo
