What People Are Saying

Rated 4 out of 5 by from Great TV This LG 65" Super Ultra High Def TV (65SJ85) has an awesome/clear picture, it doesn't matter where you site in the room it has awesome angle viewing, the TV setup is so easy when you select an option in setup it displays a explanation box which is very helpful, it also tells you if selected what other setting would be available, the power up is very fast if your in a sleep mode, online owners guide is very helpful you don't have find the book, accessing other devices on your WIFI is nice, the channel guide is good, multiple viewing if your interested watching two shows, when using the settings you can still watch your show. One con I found is when you use a Bluetooth once the TV is turned back on it defaults to the internal TV speakers therefore you have to select the Bluetooth every time you power up, I had a chat with LG and the confirmed that, I requested if that can be addressed in the latest software upgrade.

Rated 4 out of 5 by from Great TV We just set up my new LG 65" Super Ultra High Def TV (65SJ85) It is definitely a great addition to my home. It has great picture quality displaying excellent depth and dimension when watching High Def shows. Also the blacks are nice and black which can sometimes be a problem in LED TVs. There can be a bit of a glare on the screen but we do have 3 large windows in the room. The viewing angle is also very good with the whole family being able see the picture when sitting around the room. The sound is so great that we did not need to hook it up to our sound bar. When we first powered it up We were led through the set up process with the on screen guide, it was super easy and quick! The "magic motion" remote was fun to use, with it we were able to navigate the on screen menu using the gesture control or the more traditional buttons. The remote also has buttons for Amazon and Netflix which works well for us since that is where we get most of our internet programs. This TV has internet capabilities also through its WebOS 3.5 portal. You can view your Android and Windows devices on the screen, since I am an apple user I am out of luck. The TV is 35" x 57" with a width of less than 3" without the base and 12" wide at the base. It is sleek and attractive. Overall I think it is well worth the price and am sure that we will continue to really enjoy using it. Thanks LG!

Rated 4 out of 5 by from Great picture After a lot of research I had it down to 3 tvs all from Lg. I really wanted an Oled but my budget just wouldn't let me pull the trigger. I have to say I've been very impressed with the picture of this model. Great picture you won't be disappointed.

Rated 5 out of 5 by from Finally a tv that preforms in my extra-bright room I tried out 3 tvs in my living room before purchasing this one. The room has multiple windows, including a 5-window baywindow that shines directly towards the tv. The other 3 tvs I tried in this room always showed a glare that I couldn't get to clear up. This LG tv, right out of the box was an INCREDIBLE set in the right direction. After a few online tutorials of how to calibrate the picture for a bright room, the tv made us feel like we were in a movie theater!!! Crisp, super high resolution and the truest-blacks I have ever seen on a tv in this low price range. For the money, this is the ONLY tv to purchase. Once again, LG comes to the rescue and takes care of all me and my families electronic needs.

Rated 5 out of 5 by from Stunning Color; Macaw Approved! INTRODUCTION: * We own several LED TV's by LG & other manufacturers & bought 2) LG OLED TV's in 2016. The 65J8500 is the BEST LED TV I have ever seen. The stunning picture & attention to detail far exceed our expectations. PICTURE QUALITY: * The LG 65SJ8500 earned a ringing endorsement from a most unlikely source: Star, our Green-Winged Macaw! Star has always lived around a TV, but has never shown interest in the picture. Until now. One of the most colorful birds in the world can not take his eyes off of our 65" LG TV because of the indescribable colors! I uploaded 2) photos of Star mesmerized by his favorite TV. * HDR looks great on this TV (see 2 HDR photos). * The wide viewing angle allows everyone in our room to enjoy a clear, bright & high contrast picture. This is a very noticeable advantage over most competitive LED TV's. REMOTE: * I love the remote! It is the perfect size & weight. Designed with a flat base & perfectly balanced, it stands up securely, taking up much less room & providing easier access than laying flat (see several photos showing remote in vertical position). This is the smoothest operating remote I have ever seen. The remote is FAR SUPERIOR to my 2) 2016 OLED TV remotes. SOUND: * The Harmon Kardon sound system built in this TV produces the BEST SOUND I have heard from speakers built in any TV (OLED or LED). Voices are clear & easy to understand. High frequencies are good. Bass is better than expected for an internal speaker, but not as strong as you would expect from a quality Soundbar or external high power sound system, of course. * Yesterday I ordered an LG SJ8 Soundbar to compliment this TV & to bring out deep bass in movie tracks & concerts for added realism. You can even blend sound from the internal speakers with sound from the Soundbar, if you choose. SMART TV INTERFACE: * webOS 3.5 is hands down the MOST INTUITIVE, comprehensive interface of any Smart TV I have tested to date (OLED or LED). * I love the direct Amazon button on the remote! This is a new addition not found on the 2016 webOS 3.0 & provides immediate, direct access to Amazon Prime movies. * The Channel Plus app connects to 100+ FREE premium internet channels, as well. * The dedicated Netflix button is carried over from the 2016 LG remote. CONNECTIONS: * Just what you would expect from a top-of-the-line TV: 4) HDMI, 1 Composite input, 3) USB Ports, an Optical Digital Audio Out, Ethernet Port, WiFi, DLNA & Casting. Analog connections are possible by using a cable adaptor (included). * I especially like how 2) HDMI & 1) USB jacks are on the side edge, while the remainder are on a special panel in back of the TV. * If you mount this TV on a wall (which is easy to do with 4) bolts & a proper wall mount), simply use the side mounted HDMI inputs to avoid cables sticking straight out of the back. HINT: * Buy right angle HDMI adaptors to keep cables from protruding from the rear of the TV if you need more than 2) HDMI inputs that are located on the side edge. Adaptors are available that will direct cable up, down, right or left. * A right angle adaptor is also available for the screw in Coaxial Cable TV connector. CONCLUSION: * The LG 65SJ8500 is THE BEST LED TV I have seen. The beautiful colors from the Nano Cell Display push it over the edge. This is a Top-Of-The-Line Premium Quality Television! * To top it off, LG reduced the price to approximately 1/2 that of a similar sized OLED TV, making this an unbeatable value! ** The 65SJ8500 earns my HIGHEST RECOMMENDATION! **

Rated 5 out of 5 by from Excellent product! Bought this TV about 2 weeks ago. Setup is quick and painless. The picture and sound quality will leave you floored. My husband and I feel like we're at the movie theater!! The picture settings are so easy to navigate and personalize for your viewing pleasure. In fact all of the settings are easy to find and use.

Rated 5 out of 5 by from High Quality Smart Television and Easy to Use We have LED televisions from many other major brands and this LG Model SJ9500-4K-UHD-TV has set the new standard for quality. Picture Quality: The picture quality has very vibrant colors and very deep blacks from all viewing angles. The detail of the picture is astounding when displaying cable, Blue-Ray, Xbox and 4K streamed content. Sound Quality: We have a separate Marantz sound system that we typically use as part of our entertainment system that we have not taken the time to connect this television to because the sound is incredible straight from the TV. The amazing part is no one has even noticed!! You will absolutely not believe how great the sound is from this TV. I am not sure how LG puts this much into such a thin TV but it has blown us away! Technology: This television’s smart features are the best I have used so far. The remote control works like a mouse on a computer and the TV has voice recognition capabilities when using some apps that actually can understand what I’m saying! The built in apps are very easy to use and have changed the way I look at televisions. Now if I want to look up something on YouTube, I use this TV instead of my computer or smart phone.

Rated 4 out of 5 by from Love this TV I bought this yesterday, so I've only had this set up briefly. However, the picture is incredible and set up is really easy. I'm upgrading my old plasma to this model. I can't get over how awesome the picture is. My only complaint is that I can't get the magic remote to work with the dish network box. I've always stayed away from LG products because Ive always thought it was an inferior product. I read lots of reviews about this tv, and dollar for dollar this is an awesome, feature rich tv at this price point. My negative viewpoint on LG products has definitely changed.

Does this have an actual 10-bit panel? Or does the Nano Cell tech cover the additional colors?

Asked by: Curious Customer
So, the FRC method will improve all the current 8-bit content (regular Netflix, OTA broadcasts, etc) to allow @10-bit color gradients. Meanwhile it should cause no harm to 10-bit images and even support the 12-bit color depth for the built-in 'Dolby Vision' standard:-0

Will we ever see a firmware update for the Technicolor HDR mode as was shown on this TV at CES in January?  It was a major point at LG's keynote that it would be included.

What does the power supply look like?  Does it plug straight into the back of TV and into outlet?  I am asking bc we need to mount this to a wall and the sony TV had a power adapter that was bigger than a brick. If possible, can you take a picture?

Asked by: Kimmie16
This TV has a permanently attached (to the TV - through a screwed on door) white 2 prong power cord.  There is no box, just a lightweight power cable.

What is the coverage of the DCI-P3 color gamut?

Asked by: anquietas
Regrettably, we do not have any specifications for what the coverage of DCI-P3 color gamut the LG SUPER UHD 4K HDR Smart LED TV w/ Nano Cell™ Display - 65" Class (64.5" Diag), Model # 65SJ8500 is. Currently, no TV can display all of the DCI P3 or Rec. 2020 colorspace. As a result, they have to either clip colors which lie outside of their capabilities or compress the colors to fit them into the display limitations (or some combination of these two) in a process called tone mapping. There is no standard for calibrating to these wider color spaces because there is no reference of what a display should do and how this tone mapping should be performed. There are some sites that are beginning to test how much of the DCI-P3 and the Rec.2020 color volume TVs can cover, but currently, we do not have any specifications on that...^IFV
