Rated 5 out of 5 by from Great picture I was going to buy a 55" inch and chose to buy the 65" instead due to price/rebate. This is my first UHD TV and it replaced a 55" LED. This tv has a great picture!!

Rated 4 out of 5 by from 55UH7700 Review The LG 55UH7700 is a really good 4k TV for the price. Movies, TV shows look great on this TV. The game mode setting could use more work and the input lag for gaming is high. The black contrast could be a lot better when watching media in the dark.

Rated 4 out of 5 by from Great TV I love this TV. I bought it for the Xbox One X which soon comes out because this TV is 4K HDR capable and had is better than all other TVs since it has Dolby Vision. Using my Xbox One S, the HDR material looks wonderful. The sound is awesome for a TV, but I still prefer my sound bar. Picture quality is very good, but dark scenes are the only issue. When in a dark scene, if there is like a fire burning in the lower right corner, that entire portion of the screen gets light from the lower right corner when it should really be dark. This is not a huge problem but it does exist. The remote is wonderful as it can control my sound bar and cable box. The webOS software is the best television software I have ever used. Also when gaming I heard some people complain about lag time, but that is just exaggerated. In games like call of duty or Forza where every millisecond of delay could affect you, I was not affected. It was really easy to adapt to the lag time and now it doesn't even seem to be there. Overall this is a great TV, but if you can afford it, I would choose the OLED televisions.
