Rated 5 out of 5 by from with deep darks and rich colors. The netflix integration and multiple of other apps (amazon,hulu,vudu,google play movies, youtube) make it the perfect television. The magic remote can also take care of your cable boxes etc. I Have zero complaints, except the stand is a little flimsy but not a big deal. Worth the money and investment.

Rated 2 out of 5 by from Nice TV....... but The TV cord is way too short....I have to use an extension cord to plug it in.

Rated 4 out of 5 by from Jury Still Out Downloaded manual before making purchase. Specs for this 55 inch model indicated that the little v shaped legs were 33.7 inches apart. Actually 46, which meant it didn't fit my table, which meant I had to purchase a pedestal mount and wait 4 days for it to arrive. Bummer. Now we are having sound silent spots for a couple of seconds (every 10 or 15 minutes). Didn't happen with the last TV, nor with our 2nd LG TV. Checking that with our satellite provider. Picture is great. Connection to Netflix and Amazon work well. Will happily update this review after, well, further review.

How do I content share to the tv from my laptop or phone?

Asked by: lizettel
If your computer's operating system is Windows 7, Windows 8, or Windows 10, you can play music, video, or photos on your LG 4K UHD HDR Smart LED TV - 55" Class (54.6" Diag), Model # 55UJ7700 without installing an additional program. Both the TV and your PC have to be on the same network Right-click the desired music, video, or photo file, and select the model using the Play To function provided in Windows 7, Windows 8, or Windows 10 to play what is selected. You can also use SmartShare PC Software to connect the music/videos/photos saved on the PC to your home network and play them on your TV. SmartShare PC Software can be downloaded and installed from the LG website. Shared videos and photos are played from the Photo & Video APP on the TV. Shared music files are played from the Music APP on the TV. To watch the 1080p video through Content Share function, a router that uses 5 GHz frequency is required. If a 2.4 GHz router is used, the video may not play properly. The Content Share function may not be supported for a router that does not support multicast. For more information, refer to the user guide that came with your router or contact the manufacturer. DRM files in a connected device will not play and if there are too many folders or files in a folder, it may not work properly. Information on the file imported from the connected device may not be displayed either. For your phone, press the Home button on your remote and start the Device Connector app and select 'Smartphone' then follow the directions in Device Connector...^IFV

I have three tv's set up in one room. How do i get the remote to only work one TV instead of all three?

Asked by: lizettel
Unfortunately the IR functions (power, volume, channel, etc.) would be the same for every LG TV. There would not be a way to setup a LG remote to work with one LG TV and not another.
