Rated 5 out of 5 by from I was happy to know my tv could be upgraded with an app. My reason for the selection was where it was to be placed in my house.

Rated 4 out of 5 by from G8 bedroom TV I’ve had it for a couple of years. The picture quality is actually pretty great unless you’re watching a movie thatS completely dark . If you’re on a budget it’s a great TV.

Rated 2 out of 5 by from burning smell,stopped working less than 15 months Bought this tv for my husband for Christmas 2018. Smelled a burning plastic smell during our covid quarantine. Tv stopped working. Had it about 15 months. Sad to loose a tv with 3 young kids at home during our suggested/mandatory stay at home. Not cool LG, not cool.

The USB ports on the LG SUPER UHD 4K HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UH7650 are USB 2.0 ports. The advantage of using a higher rated USB cable is a minor improvement to the point of being nearly or not at all perceptible...^IFV

Will the SUPER UHDTV 4K 55UH76 that i but in the US work in Europe/Israel where they use PAL (and not NTCS Like here)?

Asked by: Michalf
Dear LGJoel, Your response is very helpful - can you please clarify if your answer is relevant only to the built-in tuner or to the cable decoders? In Israel you will need a decoder even for open channels (all channels are now digital). In addition, there are 2 major TV providers one is a cable company and the other is a Satellite based company. Both require the use of a dedicated decoder that connects via HDMI to the TV. Other services include streaming companies similar to Netflix. Those could be accessed via devices such as AppleTV. If I understand your response correctly, you are referring to a built-in tuner in the TV but assuming there is a dedicated decoder attached by HDMI - is this still an issue? Thanks.
