What People Are Saying

Rated 5 out of 5 by from TV 75 This TV has such a great picture and sound. Only took a few minutes to set up, when connecting to my service provider it was so easy to follow the prompts

Rated 5 out of 5 by from Great features Love the tv very simple to use. Speakers are clear but are not very loud.

Rated 5 out of 5 by from Outstanding Picture Impressive picture quality, colors are very realistic. The built in speakers are very good, probably the best I've heard in a TV before. Set up was easy, after it was unboxed. Worth mentioning is the weight of this TV, it is very heavy! This is a very high quality product that should last a very long time..

Rated 4 out of 5 by from Great TV! Crystal clear especially in sports. I have had this TV for two months now. Out of the box it was pretty good, however it seemed lest bright than a 6 year old Sharp Aquos. But after playing around with the picture settings I have this tweaked perfectly. Although th TV sound speakers were good, I also added a sound bar which made it better but not that much, probably not worth th emoney unless you really want thumping bass from a sub woofer. What I find annoying is the remote control, the cursor is jumpy. I rate that remote as one of the worst remotes I have ever used, probably will get used to it but the cursor remaining on the screen for a bit is unecessary. The updates seem to help so allow them. For the money this TV can't be beat. I was going to spend a bit more money and get the OLED but until they figure out the burn in I will pass. I only reason I did not give this 5 stars is that stupid remote. There was nothing wrong with the old school method of scrolling down to find the menu item you needed. I would reccomend this TV

Just to clarify, there isn't an 75SJ8570 that has a panel made in Asia as opposed to the one made in Mexico? TVSuperstores lists the model number as 75SJ8570(US), same TV, correct?

Asked by: GKepColo
LG is an international company that has factories worldwide and parts for the LG SUPER UHD 4K HDR Smart LED TV - 75" Class (74.5" Diag), Model # 75SJ8570 may come from a factory in any of those countries where LG has factories and the TV might be assembled in an entirely different country. Typically, on the shipping carton that the TV comes in, it will indicate where the TV was manufactured or assembled. Regardless of where it was manufactured or assembled, as long as the model number, i.e. 75SJ8570 is the same, the TV is made to the exact same specifications. The ")" at the end of the model number indicates the type of built-in digital tuner in the TV which for the U.S. is the ATSC tuner...^IFV

Having trouble differentiating between LG75SJ8570 and LG75SJ8570-UB.  What is the difference in the UB version?  I’m told by Joe’s AV it’s the 10-bit panel.  Please advise - thank you!

Asked by: joolive2
The LG SUPER UHD 4K HDR Smart LED TV - 75" Class (74.5" Diag), Model # 75SJ8570 and Model # 75SJ8570 are the same TV. People usually don't append the "UB" to the model number. On TVs that have a different appendage at the end of their model numbers would indicate a difference in the internal components, but will have the same functionality if the model numbers are the same...^IFV
