Rated 4 out of 5 by from One problem I’ve had this tv since last fall and it has been excellent until yesterday when while I was watching it it fell from my entertainment center! The screws came out of the stand. I turned it off and replaced the screws, rehooked it up and the screen was shot. I still plan to purchase the same tv.

I recently bought a 43LK57 43 inch t.v It says ACTIVE HDR but when connected to an Xbox I cannot turn on HDR10, nor does the t.v send the correct EDID info to the xbox resulting in 640x480 resolution.

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
