I have LG smart tv 43LK57. I have wired headphones but tv has no headphone jack which is stupid. So then I thought I could use wireless bluetooth headphones but the 43LK57 doesn't have bluetooth either. I need a solution to this problem.

Asked by: sport419
The 43LK5700PUA does not have inputs or bluetooth that would allow the connection of headphones. We apologize for the inconvenience. ^CP

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
