Very good tv am impressed with LG


This tv has a very good picture quality and good viewing from side angle to. Had no problems with WiFi very easy set up. If you plan to use Xbox to game on the TV you will need to switch pitcher to game mode or you will get lag response with game...

Easy to set up, good image quality


I was shopping for a reasonable cost, good quality 40 inch TV. Image quality is good and setup was easy. I wish however a better manual had been provided

Great picture


The resolution of the picture on this TV is impressive. If our band width were sufficient, we would love the smart TV features. Maybe someday...

Love LG


I love LG products! Great quality! Second LG tv I have purchased. Got a really good deal on this 4K tv. And I have to give props to the salesman. He was good. My only issue (and I'm partly to blame for not asking) but I never knew my tv was only 65 Hz....

An excellent value for a 4K HD TV


I scoped out a few different 4K TVs in the 43" class, but the combination of the quality of the 4K display and the price of the LG just couldn't be beaten. The Smart TV features are also very cool and fairly easy to use.
