What people are saying

Rated 3 out of 5 by from Great Television with great features I have loved the TV and everything about it from a use standpoint is great. The picture quality is great. The only issues i have had are with the magic remote, it keeps losing it's floating cursor from time to time and also the black levels of the picture at night time are not consistent. There is like a circus of moving black levels scrolling across the screen. It could be due to the technology of LED backlit screens as i had the panel replaced on warranty and the new panel still did the same thing.

Rated 5 out of 5 by from Great Television I could not be happier with this LG television. The picture is great once you figure out calibrating it. It has decent audio from its speakers which is rare in televisions. The remote is really cool as it has a mouse like function which makes it navigating it easy. Highly recommended.

My TV was originally wall mounted but I moved and need to find a TV Stand for my 55UJ7700. Is there a LG replacement stand or do you have a recommendation something else? I believe the VESA on the 55UJ7700 is 300 x 300. Correct? Thanks

Asked by: rhein794
Hello, to place the unit back on the original legs, you will need to purchase 1 each of the following parts: MJH64496002, AAN75832033, MJH64476301, AAN75832034 and they can be ordered from https://encompass.com/ ^AC

How do I access my Verizon Fios DVD player on the LG UJ7700?

Asked by: mgm64
Hello, this will depend on how you have it connected. If your DVD player is connected to the TV via the HDMI 1 port, you will put the TV's input on HDMI 1 to view the DVD player. ^AC

Does the 55UJ7700 have Picture-In-Picture or Picture-And-Picture? I like to watch a program while monitoring another, such as a sporting event. If that model doesn't have that feature, are there other models that do?

Asked by: Jerbearesq
The Multi-view feature on the LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700 allows you to split your screen so you can watch two braodcasts or exyternal inouts simultaneously. Multi-view may not be available for Ultra HD channels and it cannot be used at the same time with Live Playback. When you run the feature for the first time, one of the screen shows the Live TV you recently watched or an external input. The feature then memorizes the combination of settings for the two screens and provides them for future use...^IFV

I just bought an LG 55UJ77 TV but need a different base stand—one that supports in the center of the TV. There appears to be a spot on the TV back. Do you sell one? Or is there a compatible one available? I’d hate to have to return it. 

Asked by: Cindy Mimi
Hello, the holes on the back of the TV are for a wall mount, there is only one set of legs for the unit. ^AC

Can one person listen to tv speakers or a sound bar at the same time as the other hard of hearing person listens w/ bluetooth headphones?

Asked by: Dan 55
On the LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700, you can configure the Digital Sound Out settings to play simultaneously through the built-in speakers in the TV and a SoundBar connected via the TV's Optical Digital Audio Output. Regrettably, you cannot do the same when using Bluetooth Headsets. When you pair the TV with a Bluetooth Headset, you can only listen to the TV through the Bluetooth Headset...^IFV

What size are the screws on the back of the TV for using a wall mounting bracket.  I have a bracket from my last TV but the bolts that attach to the back of the TV are not the same size.

Asked by: Craig K
The screws that will fit into the bolt holes in the back of the LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700 have a metric measurement which is given as M(?) x L(?) where "M" is the width of the screw and "L" is the length. The length will vary depending on the depth of the wall mount you're using. Typically, if the wall mount you're using is a VESA Compliant Wall Mount that supports the same A x B VESA Wall Mount Pattern for the TV, which is 300 x 300 (mm) for this TV, it should have come with the correct VESA STandard screws that would fit into the TV. The width of the screws that will fit into this TV is M6 (i.e. 6 mm). You can measure the length of the screws you currently have to determine what length you will need or you can check the instruction manual for your wall mount for that. I know that LOWE's carries these screws in various widths and lengths so you will be able to get them from them. Most hardware stores will also carry these screws...^IFV
