Rated 4 out of 5 by from Nice TV I have owned this television for some time now. The picture and performance are excellent. Easy of use is pretty good as well. The only negative is that the sound is not good. Each channel is different and the sound fluctuates when changing from talking to sound effects and music. Not sure how to fix this

Rated 3 out of 5 by from Excellent picture but disappointed that I see the banding especially when the background is a lighter color or watching sports. I have been loyal to LG products. 2 tvs, blu ray players, washer, dryer, phones, etc.. wish I could have gotten a tv that does not have the banding issue

Do we need 4K HDMI CABLE to get better resolution?

Asked by: R Sanchez
The recommended types of HDMI cable to sue with the LG 4K UHD HDR Smart LED TV - 65" Class (64.5" Diag), Model # 65UJ6540 are the High-Speed HDMI®/™ cable or the High-Speed HDMI®/™ cable with Ethernet. The cables should be 3m or less in length and make sure they have the HDMI logo on them so you know that they are HDMI certified. The TV has a native resolution of 3840 x 2160 and will always play any video content at its native resolution or as close to it as it can get the video signal if the video signal has a lower resolution than the TV. When presented with a lower video signal, the TV has a built-in 4K upscaler that will upconvert the signal to the TV's native resolution or as close as it can get it depending on if the incoming signal has enough data to upconvert it to the TV's native resolution. That will determine the quality of the picture you get...^IFV

compatable surround sound for 65uj6540

Asked by: 7649
JBL 3.1 soundbar is awesome and has a total 450 Watts. Bass is excellent and adjustable and speech clarity is excellent as well. We even prefer the normal sound settings over surround, it’s that good. We went through 3 sound bars before settling on this one.
