The LG 55SJ8500 is a beautiful television that can delivery absolutely stunning imagery. A quick demonstration of “store mode” will easily convince you that this is true. But before you place the 55SJ8500 in the cart, you should be aware of how this set performs under various real world conditions – and while many aspects will continue to delight, some may disappoint. Read on to discover why.

VISUAL ACUITY: It is worth quickly reviewing the concept of visual acuity. At a high level, visual acuity can be considered the limits of the human eye.

Pop quiz – which has the larger physical size, a golf ball or the moon? The moon, of course. Which has the larger *angular* size? Now the answer depends on a point of perspective. Hold the golf ball close enough to your eye and it will appear to be larger than the moon, hold it far away and it appears smaller than the moon.

Now apply this concept to the pixels of the 55SJ8500 and consider the limitations of the human eye. The human eye can see individual pixels when the pixel has an angular size of 1 arcminute or larger (when drawing a line from your eye to the left edge of the pixel, and then another line from your eye to the right edge of the pixel, the angle between these two lines will be 0.17 degrees). When the angular size of the pixel is smaller than 1 arcminute, adjacent pixels blend together and increased resolutions cannot be detected by the human eye.

All this to say, be informed of the advantages of a 4k display. It’s not the physical resolution that you should be concerned with, it’s the angular size of the pixels from where you intend to view it. At a 55 inch diagonal, 4k resolution will be discernable at approximately 5 feet or closer from the screen. Measure your room and beware the siren call of 4k. At 8 feet away or greater, there is no advantage of UHD over HDX resolutions on a 55” television.

PICTURE QUALITY: Under the correct conditions, the 55J8500 is a real beauty. For example, when viewing David Attenborough’s Life documentary in HDX resolution, the imagery of panning earth landscapes and slow motion wildlife is breathtaking. LG’s 4K scaler performs with admirable results and the TrueMotion technology interpolates the motion to a convincingly fluid 120Hz. And when viewing 4K UHD HDR content such as Amazon’s original Just Add Magic series the results will blow you back into your seat, the clouds will part, and the obligatory angelic choir from the heavens will bless you. However, when viewing certain native UHD HDR content, such as Amazon’s original Goliath series, the results often disappoint. Additionally, Playstation 4 HDR gaming content can significantly frustrate and underwhelm, depending on the scene. To understand why this discrepancy exist, let’s once again dive into the technical details.

The LG 55SJ8500 is a backlit LCD/LED display. This means that many LED chips produce the pixel color that you see, while fewer LCD chips produce the light. There are less LCDs producing luminance than there are LEDs producing color.

For comparison, a more expensive OLED display has an LED chip that produces both the color and the luminance, thus each pixel can control luminance independently and each pixel can be turned off completely. This technology is generally considered superior to backlit LCD/LED technologies, and is more expensive.

There are two ways for the less expensive backlit LCD/LED televisions to provide the luminance – edge lit or array lit. The LG 55SJ8500 is edge lit. This means that the luminance is provided by LCDs around the edges of the screen, unlike an array lit television that provides the luminance in partitions directly underneath the screen. LCD/LED edge lit televisions, like the LG 55SJ8500, are the least expensive and generally the poorest performers of these technologies.

In order to increase contrast ratios, backlit televisions like the 55SJ8500 use a technology called “local dimming”. That means that the computer inside the television will analyze the information on the screen, and turn off the LCD light on areas of the screen that are black. Without local dimming, blacks appear as washed out grey tones on LCD/LED displays. This technology works most effectively on array lit screens. With edge lit screens, like the 55J8500, only an entire vertical band can be dimmed.

In practice, imagine a black background with a 1 inch white circle panning from the center left to center right of a 55” edge-lit local-dimming display. The computer will analyze the image and determine that large areas of the screen are black, so an edge lit display will dim the LCDs located on the top and bottom edge of the screen in these areas. But the vertical band that contains the white circle will remain lit – not only underneath the white circle but also in the entire vertical band extending above and below the circle. This causes serious black level conformity problems. As the circle pans from the left to the right, a grey washed out vertical band will travel with it where the LCD edge remains lit.

This problem is very noticeable and distracting in darkly lit scenes where part of the vertical band is lit with a bright HDR effect and the top or bottom of the area is black. Imagine a scene of a dark restaurant with two gangsters conspiring at a table. A light overhangs the table and a sunlit window appears in the background. HDR and local edge lit LCD dimming will destroy this scene on the 55J8500 and the picture quality will be disappointing. Now imagine a brightly lit landscape with a fox bounding through fields of gold. Now it will look absolutely stunning!

And thus will be your experience on the LG 55J8500. The picture quality is very dependent on the scene. Want to bet that the “store mode” demo completely hides the significant shortcomings of the technology while trumpeting the strengths?

SOUND QUALITY: The LG 55J8500’s 40 watt stereo internal speakers coupled with its 20 watt subwoofer, designed by the Harmon/Kardon company, incorporates Dolby Atmos technology. What does this mean? A microphone on your remote control is used to calibrate the technology to leverage the natural acoustics of your room to deliver atmospheric 3D sound. The software running on the LG becomes intelligent and aware of how sound bounces from walls and ceilings, and computes the output signal dynamically. This is unlike traditional Dolby Surround technology, where the audio is hard-coded to be delivered to specific speakers.

Is it a gimmick? No, it works and it works very effectively. When watching Terminator Genisys using the internal speakers, I was convinced that I was hearing a 7.1 surround speaker setup. Bullets whizzed from the screen to the back of the room. The rumble of unseen helicopter blades were heard behind me and Brad Fiedel’s classic Terminator theme filled the room completely. Wow, very well done! I’m impressed.

That’s not to say that the LG 55J8500’s internal technology tops an amplified home theater setup, it doesn’t. But the optical pass-through output on the back of the 55J8500 allows the audio signal to be sent to an external system easily. So switching from internal sound delivery to an external home theater system is a very simple setup. There is an option in the software to use both the internal speakers and to pass the signal through an optical output, so simply mute the television volume and turn on your receiver. Done. Turn off the receiver and increase the television volume and you’re back. I really appreciate this single cable setup that allows delivery of the audio signal from the internal software applications to an external home theater receiver.

MAGIC REMOTE: LG’s amazing Magic Remote is worth highlighting. This is simply the best remote control I have used on a television. It has an internal accelerometer that can place a mouse-like-cursor on the screen for navigating the software interfaces. A microphone allows voice commands at the touch of a button and also serves as a calibration tool for the Dolby Atmos technology. The Magic Remote is ergonomically appropriate and feels great in the hand. A centered scroll wheel also acts as a push button that can activate the cursor or function much like an enter key. If the cursor is motionless for 5 seconds then it disappears. Rest assured, you are getting one of the industry’s best remote controls if you decide to purchase the LG 55J8500.

SOFTWARE: Before I get ahead of myself and start singing the praises of LG’s WebOS 3.5 interface, let’s take a quick look at the Terms of Service and Privacy Policy in which you must first agree. I’ve read each tier of this contract in its entirety and I can safely conclude that this is an Orwellian nightmare of an agreement. In a nutshell you are agreeing to let LG collect personally identifiable information and keep all content you introduce to the LG 55J8500 indefinitely, and you agree to allow LG to sell this information to third parties without restriction. Perhaps LG’s intentions are not nefarious, but keep in mind that there is an advanced computer inside this television that is analyzing every single frame and it is connected to LG’s remote computers through your internet service. Couple this with modern artificial intelligence algorithms, such as deep learning, and the potential for abuse is considerable. The software Terms of Service and Privacy Policy get a grade of F. Go stand in the corner, LG.

But contract aside, the user interface itself and the provided software get an A+ with a smiley face. It’s beautiful, responsive, intuitive, and appropriate. Navigation is very fluid and all icons and fonts are sized appropriately. A gear icon button on the remote pulls up a quick menu on the right side to quickly change common settings with minimal distraction on the screen. Another dedicated button brings up an animated row of applications on the bottom of the screen. Two dedicated buttons are also on the remote, one for Netflix and one for Amazon, and will instantly launch the associated app.

Using peripheral hardware with the LG 55J8500 is possible through the interface. Miracast screen mirroring eventually worked with a Sony Xperia Android smartphone with a few connection attempts, so this didn’t go quite as smoothly as it should have. Bluetooth connections to headphones, on the other hand, worked flawlessly and switching audio back and forth is a breeze.

Both VUDU and Amazon worked very well. Having the mouse-like-cursor on the Magic Remote benefits both of these applications. No longer are you restricted to using digital up, down, left, right buttons – you have a full analog screen cursor and a scroll wheel to navigate through the content. Each of these applications animats through lists smoothly when the cursor reaches an edge, and the scroll wheel further enhances navigation. The user interfaces of these applications on the LG 55J8500 are superior to the Roku 3, PS4, or Amazon Fire Stick counterparts. Amazon additionally has dedicated channels for its UHD/HDR content that makes finding high quality 4K content easy.

Bringing your own content to the LG 55J8500 is simple via the provided USB ports located on the back and a user-provided external USB 3.0 drive. Scrolling to the content is as simple as choosing the LG provided software player and selecting the appropriate video icon. 4K H.265 MPEG content looks beautiful, starts immediately, and is easily controlled via the Magic Remote and LG software.

Other customizable options are available, such as pinning frequently used applications and storing custom user modes for quick access. Using the LG interface is immediately intuitive, while discovering new and advanced functionality is never frustrating.

The User Manual is also integrated into the software interface and makes learning very accessible. There are options within the on-screen User Manual to take a “tour” of features and the software will walk you through the various settings and functionality. From within the interface, hovering the cursor over a setting will also pop up an information window describing the options. Bravo!

SHIPPING AND SET-UP: The LG 55SJ8500 shipped from Amazon in its original packaging, so it’s going to be obvious what the box contains while in transit. Delivery companies can be brutes when it comes to the treatment of property, and this was confirmed by the appearance of the box when it arrived. The corners were dented and there was a long puncture scrape on down the back. Luckily there is a few inches of space between the outside of the box and the screen, and another quarter inch thick piece of Styrofoam in front of the screen. In this case, the television inside arrived undamaged.

There is a quick setup guide inside the box, which doesn’t exactly correspond to this model. It was not very detailed and caused some confusion. Removing the television from the box requires two people. The instructions suggest placing the television front side down on the box in order to install the stand. If mounting to a wall, you will use a VESA 300×300 compliant wall mount. The unit weighs about 45 pounds. Several warnings strongly advise against applying any pressure at all to the front screen, so be careful.

When mounted on the stand, the unit is wobbly. The stand is connected via four screws into a plastic frame. Touching the top frame of the LG 55J8500 will cause it to sway back and forth. I would not recommend installing this on the stand where children can get to it, it just doesn’t seem that stable. Mounting it to a wall might be a better choice.

PHYSICAL AESTHETICS: A beautiful display be any standard. LG understands the art of subtle branding and deserves a round of applause – the LG branding is mostly hidden underneath the screen near the standby light. The stand has larger lettering on the right side that states “SUPER UHD”. The micro bezel is hidden by a flush front, while the outer edge is offered in a tasteful silver metallic. The plastic back of the television is all white. There are two sets of input/outputs, one that is accessible from the side (useful for a wall mount) and another set directly in the back. Mounting brackets are provided in a VESA 300×300 standard configuration.

SUMMARY: At the time of writing this review, the 55SJ8500 is a new product for 2017 that was just launched by LG. The MSRP price tag is high today, but will most likely drop in the future. This is a beautiful television and performs admirably on a wide variety of content. There will be times that it will be breathtaking, but at other times it will disappoint. The 55J8500 does a lot right – Dolby Vision, LG’s 4K scaler, Dolby Atmos and sound by Harmon/Kardon, LG’s Magic Remote, 120 Hz TruMotion, LG’s webOS 3.5 software interface, and the physical aesthetics of the product. There is a lot here to love! Watch out for the Orwellian User Agreements, you are compromising your privacy to use the amazing software. And ultimately this is still an edge lit LCD/LED television with local dimming, and the limitations of this technology cannot be avoided. Do your homework, check your budget, measure your room, and optimize your purchasing decision. Hopefully this review will help you with your quest.

Very good TV
This is a television capable of an exceptional picture; do not stop after the basic installation process, though. You will be helped greatly by going to the LG web site and downloading the user’s manual. Also, do adjusting selections while watching a known source of good, sharp pictures – I used Dish Network’s live sports channels. I am 85 years old; my wife is 84. I have expensive hearing aids, she does not. I had hoped to not have to buy a supplemental sound bar to help hear dialog over the awful background music so widely used these days, but after trying everything in the book, and knowing some programs are broadcast with subpar audio, I ordered a sound bar for this TV. Younger owners may be satisfied with the stock sound output by the speakers; they are better than most; volume is fine. Speaker evaluation is largely subjective. Only you can judge if it is adequate. I spent a great deal of effort trying to clarify the voices using all of the options (there are many combinations available) but was unsuccessful in achieving voice clarity in many program selections. I did order a sound bar; it has not yet arrived, so it may prove to be of little help. I rated this TV a 4-star; the picture is definitely a 5-star picture, and I have not yet viewed any broadcast 4K.

The dialog above is a review I sent LG; since then, I have received and added a Yamaha YAS-107BL sound bar. It definitely helped in our situation; again, sound evaluation is a subjective matter, but this combination made it 5-star in both sight and sound.

Update on November 28: I experienced a vertical line during the return window time, but resisted returning the TV to Amazon. I managed to get the line to disappear, so was not too concerned. A mistake; the line comes back in various positions periodically. Purchased new cables – no help. So far, I have been able to cure this problem by turning the TV off and wiping the screen vertically from top to bottom with a clean microfiber cloth, a trick I saw on YouTube. I hope this continues to work.
Disappointing for such an expensive television.
