What People Are Saying

Rated 5 out of 5 by from Really outstanding picture! This TV was a Christmas gift to me from my wife, and I absolutely love it! It's replacing an old 32" flat screen that wasn't HD. Now I'm tempted to go out and get a 55" or bigger to replace the flat screen (not HD) in my man cave. You will not be disappointed in this terrific product!

Rated 5 out of 5 by from Great television I bought this before looking at the reviews. Some said that you needed to purchase an additional remote...but the remote that came with it works just fine for me. Excellent volume. My WiFi does not disconnect. And the ease of the apps are a life saver.

Is this tv 4K? What exactly does that mean?

Asked by: EClaud109
Hi EClaud109. As implied in the title description, the LG LK5700PUA HDR Smart LED Full HD 1080p TV - 43" Class (42.5" Diag), MOdel # 43LK5700PUA is a 1080p TV, it is not a 4K TV. It has a resolution of 1920 x 1080. 4K TVs are those that have a resolution of 3840 x 2160 (also referred to as 2160p). The numbers for the resolutions refer to the number of pixels horizontally and vertically and if you multiply the numbers to get the total number of pixels, a 1080p screen has a total of 2,073,600 piexels and a 2160p screen has a total of 8,294,400 which is 4 x the total number of pixels as a 1080p screen, hence 4K...^IFV
