The LG SJ8500 LED 4k TV is a good smart TV with decent picture quality and better than average viewing angles. It gets decently bright in HDR, and it can display a wide gamut of colors without gradations. Its input lag and motion blur are both notably low, making it a good choice for gamers. Unfortunately though, its blacks aren't very deep and its uniformity of both greys and blacks is quite poor overall.

Design

Curved : No

The design of the SJ8500 is very similar to the UH8500 from 2016. It has the familiar arc stand which looks great, and sleek borders. It is quite thin when viewed from the side and will certainly stand out in any room. Unfortunately there are some practical limitations as the inputs may be difficult to access if placed close to a wall and the cable management is sub-par.

Stand

The stand is very similar to the UH8500 and UH9500 from 2016, with the addition of 'Super UHD' branding. It supports the TV quite well, but does wobble if knocked.

Footprint of the 55" TV stand: 9.8" x 33.0"

Back
Wall Mount : VESA 300x300

The rear of the TV is also very similar to the 2016 UH8500. The cable management is notably worse though, as the cable guide has been replaced by a single hook. The inputs have also been rearranged slightly which unfortunately means that many of the inputs are difficult to access if placed close to a wall.

Borders
Borders : 0.39" (1.0 cm)

The borders are thin and look good, at about two thirds of the thickness of the UH8500 from last year.

Thickness
Max Thickness : 2.56" (6.5 cm)

The TV has an average thickness, although it appears thin because these protrusions are near the base of the TV.

Temperature
Maximum Temperature
:
97 °F (36 °C)
Average Temperature
:
88 °F (31 °C)

The TV runs fairly cool, only getting a little warm to the touch in a few places on the back and on the bottom edge, where the edge lit LEDs are. Fortunately the bottom edge is where most of the vents are.

7.0 Build Quality

The build quality of the SJ8500 is decent. The rear of the TV is all plastic, but doesn't have too much flex.

7.1

Picture Quality

The LG SJ8500 LED TV has a better than average picture quality. When set in a dark room, the unremarkable contrast ratio and the disappointing black uniformity mean the SJ8500 render black scene very poorly and blacks end up looking more grayish than really black. The SJ8500 does not really fair better in a bright room since the SDR peak brightness is not really high enough to fight glare from a bright light or window and it could be better at dealing with reflection. The gray uniformity is decent and the dirty screen effect is minimal, which is good especially if you intend to watch a lot of sports. The viewing angle is not bad so the SJ8500 could be a good TV to watch a big sports event with a large group of people since even the people sitting off center could have a similar picture quality as those right in front. Finally, when it come to HDR, the SJ8500 can reproduce a wide range of color since it has a wide color gamut and with its decent HDR peak brightness, it can reproduce relatively bright highlights. But since the local dimming is poor, it cannot really get brighter and limit the blooming at the same time.

6.6 Contrast
Native Contrast
:
1379 : 1
Contrast with local dimming
:
1423 : 1

The native contrast ratio of the SJ8500 could be better. For an IPS TV, this is in the higher ranking, but it is nowhere near what most of VA TVs usually have. With this low native contrast ratio, when set in a dark room, this means that blacks won't be very deep and will look more grayish than really black. As a result of this, dark room performance really takes a hit and dark scene end up looking washed-out rather than really dark.

If set in a bright room, the effect of a low native contrast ratio will be less noticeable and this is some of the reason that IPS TVs are more recommended for room with a lot of light.

When the local dimming is turned on and set to maximum, the contrast ratio goes up a little bit but is still far from what you would get from a good VA TV.

1.5 Local Dimming
Local Dimming
:
Yes
Backlight
:
Edge

The local dimming feature of the SJ8500 is bad and is not better than on most other edge-lit TVs. When compared to the 2016 LG UH8500, the local dimming does behave very similarly, without much appreciation over the last iteration. Looking at our contrast ratio test, we see that it can't really make the contrast that much better.

Most of the time, you should turn on the local dimming to high, since it can help a bit make black a bit deeper, but if you notice the luminosity screen changing too much by itself, you can set the local dimming to medium or low. In the case that you really find it annoying, simply set the local dimming off.

Okay SDR peak brightness, fine for a dim room but in a well lit room the TV may appear too dim. The brightness stays fairly consistent, only dimming a bit during very dark scenes like our 2% white window test. The real scene brightness is measured near the edge of the screen, which isn't as bright as the center. Overall the SJ8500 isn't as bright as the UH8500 from last year, though there's less dimming of dark scenes. A plot of brightness over time is shown here.

Mediocre HDR peak brightness. The TV's local dimming brightens highlights in dark scenes fairly well, as shown in our smaller window tests. However the real scene brightness is quite low for HDR highlights, nowhere near as bright as many of its competitors or the UH8500 from last year. The brightness also cycles dramatically when shown a still image, as seen in this brightness plot, however this shouldn't be a problem when watching moving content.

5% DSE
:
0.110 %

The overall gray uniformity of the SJ8500 is decent. Dirty screen effect is minimal and not too annoying while watching sports like football or soccer, which is good. The standard deviation is high and most of the uniformity issue come from the side of the TV being darker than the center. The bottom and top are a bit brighter, but it is not too much noticeable when compare to the darker sides.

When it come to the 5% gray uniformity test picture, nothing really come up beside some faint brighter spots where there was some major flashlighting on the black uniformity test picture. But it is not too much a problem on this test here, since the uniformity of the 5% gray is much better.

6.2 Viewing Angle
Color Shift
:
21 °
Brightness
:
27 °
Black Level
:
75 °

Mediocre viewing angle, better than any VA TV but not as good as OLED and some other IPS TVs. The black level remains virtually unchanged at an angle, but colors shift and brightness decreases when viewed from only a small angle. Still, this viewing angle makes the TV suited for a room where people often view the TV from the side.

3.6 Black Uniformity
Native Std. Dev.
:
3.075 %
Std. Dev. w/ L.D.
:
5.078 %

The black uniformity of this LG TV is bad. Some flashlighting and clouding issues can be seen near each corner of the screen which affects greatly the uniformity of the screen when displaying a black image. Black uniformity issues are usually a bit more present on IPS TVs, but the SJ8500 is definitely worse than most of them.

With the local dimming feature turned on, most of the flashlighting issues that were visible in the corners are not visible anymore, but a large vertical blooming zone is now visible where the white cross is in the middle. This is mostly due because the local dimming zones span over a vertical zone that goes from the bottom to the top of the screen.

Note that once again here, we do not measure the black level, but the uniformity of the screen.

8.7 Reflections
Screen Finish
:
Semi-gloss
Total Reflections
:
3.4 %
Indirect Reflections
:
0.5 %

The SJ8500 is good at handling reflections. It has a semi-gloss finish which diffuses reflections a bit, reducing their intensity. This is a similar result to the UJ7700 and should be fine for most rooms, but very bright glare may present an issue.

6.7 Pre Calibration
White Balance dE
:
3.82
Color dE
:
3.95
Gamma
:
2.35
Color Temperature
:
6245 K

Out of the box, the accuracy is good, but not as good as the 2016 UH8500. The white balance is on the warm side and the dE is high enough so that TV enthusiasts could notice it. The gamma is a bit high too and the curve is not tracking our target too closely.

When it comes to the color, the color dE is a bit high too and enthusiasts could notice it. Most of the color are a bit off, with only the blue and cyan being a bit more off than the rest, but overall it is not that much a problem.

On a side note here, when we say that enthusiasts could notice it, we mean that a person that already calibrated or use a calibrated TV could notice some little imperfection. For most people, that are simply buying a new TV to replace an older TV, this level of imperfection is still very little and most of the new TV are usually far better than any older TV when it come to color accuracy.

9.5 Post Calibration
White Balance dE
:
0.15
Color dE
:
1.39
Gamma

2.20
Color Temperature
:
6504 K

The calibration process of the LG SJ8500 was done without problem and the whole calibration session was done very fast, as with other LG TVs, thanks to the 2 and 20 points calibration. The white balance dE was brought down to a negligible 0.15, which is excellent. As the result of this correction, the gamma is now tracking our 2.2 target and the curve was also flatened.

The color space management provided by LG on the SJ8500 was very helpful to get the dE from 3.95 to 1.39, which is an excellent result. The white point, that was a bit off before calibration is now right spot on and most of the color are also tracking much more closely their targets.

You can see our recommended settings here.

8.0 480p Input

Upscaling of low quality content such as DVDs is good. Like other LG TVs, some halo artifacts can be seen along straight lines but this isn't too bad.

8.0 720p Input

720p content such as cable is upscaled well. Details are preserved.

9.0 1080p Input

Full HD content such as Blu-rays look good. The image remains detailed and clear.

10 4k Input

No issues can be seen with native 4k content and the image is sharp.

Good wide color gamut, though not as wide as high end TVs. The TV falls a bit short at reproducing fully saturated red and blue, and quite short for saturated green. However, nearly all modern TVs struggle with greens. On the bright side the TV is fairly accurate at showing the colors it's able to, so most colors in HDR content will be shown accurately.

The TV's EOTF follows the HDR PQ curve remarkably well, except at the extreme low end, where it actually turned off the screen when shown 5% and 10% grey slides. It doesn't do this for colored 10% slides, as seen in the color volume test. This likely won't be an issue for normal content, as this is a very extreme case. This EOTF was measured in the 'Cinema' picture mode, the EOTFs for 'Game' mode and PC mode are here and here, and are also fairly accurate. The 5% and 10% grey slides were not turned off in PC mode.

Update 11/10/2017: LG's new Active HDR feature (Dynamic Contrast: Low) improves the EOTF considerably, so we recommend enabling it. Unfortunately Active HDR doesn't work in Game or PC mode.

Mediocre color volume. The TV's color gamut narrows significantly for very dark colors, and its black level is not very good because of its IPS panel. This color volume is similar to last year's UH8500, but a little worse for dark colors.

not tested Gradient
Color Depth
:
10 Bit

The SJ8500 performs well in our gradient test and no banding that is normally seen on an 8-bit panel can be noticed here. Overall, this is a good result and is a bit better than what was seen on the 2016 UH8500. Some little imperfections can be seen in the dark blue and green, but besides that, it is a very smooth gradient.

Update 03/08/2018: The gradient test was overhauled for Test Bench 1.2, but we're unable to retest our SJ8500 (it broke, see our Additional Review Notes); because of this the SJ8500's gradient test has been removed from its scoring, without bringing any penalty or benefit.

The SJ8500 does present some image retention, but it is faint and goes away relatively fast. When compared to the 2016 UH8500, which have a very strong retention, where even the color of the logos of the burn-in scene could still be noticed, now on the SJ8500 you can only see a faint shadow of the logos. Also on the UH8500, the retention lasted for more than 4 minutes, as now on the SJ8500, it is gone before 2 minutes of recovery.

10 Permanent Burn-In Risk

No

Although some IPS panels can suffer from temporary image retention, this doesn't appear to be permanent as seen in our long-term test.

Pixels

The chevron shape of the IPS pixels is visible when viewed from close up.

7.5

Motion

The motion handling of the SJ8500 is great. The response time is fast, resulting in only a very short trail following moving objects. The backlight flickers when it dims, and although this isn't noticeable to some people it does result in slightly less smooth motion. Unfortunately, it is not possible to increase the amount of visible flicker to clear up content. Movies played from any source are smooth and the TV is able to interpolate content up to its native refresh rate of 120Hz for those who enjoy the Soap Opera Effect.

8.3 Response Time
80% Response Time
:
6.0 ms
100% Response Time
:

The response time is great, so only a short trail can be seen following fast-moving objects. This is similar to the UH8500 from 2016.

4.0 Flicker-Free
Flicker-Free
:
No
PWM Dimming Frequency
:
120 Hz

The TV uses PWM at 120Hz to dim the backlight, starting at 100/100 backlight setting. Lowering the setting shortens the duty cycle, while amplitude remains nearly constant down to very low backlight settings. Backlight PWM helps clear up motion slightly, but results in duplications following fast-moving objects, visible in the motion blur box.

Like with other 2017 LG TVs, there is no option to reduce the flicker frequency to 60 Hz, although its 120 Hz PWM flicker does help to make motion look clearer.

10 Motion Interpolation
Motion Interpolation (30 fps)
:
Yes
Motion Interpolation (60 fps)
:
Yes

The SJ8500 has a 120Hz panel and can interpolate lower frame rate content. There are some bugs in the interpolation which causes more stuttering than usual, especially with our full-screen pattern. To enable motion interpolation (also called the soap opera effect) set 'TruMotion' to 'User'. For a 30fps source increase 'De-Judder' and for a 60fps source increase 'De-Blur'. The 120Hz panel can produce a strong soap opera effect like the UH8500 from 2016.

7.6 Stutter

The LG SJ8500 is good at displaying 24p movies and 60Hz content without stutter. The response time of the LCD helps to blur the transition between frames, producing smooth motion even on wide panning shots.

Yes

The SJ8500 can display 24 movies without judder playing from 24p sources like DVDs or Blu-rays and also from 60p/60i sources like cable boxes. This is great results, especially for people that are sensitive to judder.

To remove judder from any sources, the 'Real Cinema' option from the 'Picture Options', must be turned on. We found that this option was able to remove judder from 24p movies without problems. During our testing, we also experimented with the 'TruMotion' option and we found out that while set to 'User' with both sliders ('De-Judder' and 'De-Blur') set to 0, the SJ8500 was also able to remove judder and this without adding any soap opera effect. So either option could be used to remove judder.

Outstanding low input lag, good enough for even competitive gamers. Normally only the 'Game' picture mode has low input lag, but when the input's icon is set to 'PC' all picture modes have the same low input lag and display proper 4:4:4 color (though some settings are disabled). This input lag is a huge improvement over last year's UH8500.

We are unable to test the 120Hz input lag as our SJ8500 is no longer in our lab (see here).

With webOS update 3.6 LG has fixed the PC mode HDR issue, so now 4:4:4 color is properly displayed in HDR content in PC mode. 120 Hz is listed as a possible resolution on a PC, so no custom resolution is needed.

Sound Quality

The SJ8500 is nothing exceptional, but it does better than average. It has the advantage of being able to be tuned for the room, which does a good job at reducing the effects of resonance. It's still not good enough to skip getting an external solution for a better experience though.

Smart Features

Version : 3.5

The SJ8500 runs LG's webOS smart platform, which has a lot of features and low level options while still being easy to navigate. The remote has a few buttons that open quick menus to easily change common settings, yet digging deeper into the interface reveals many low level options. The remote has a few smart features that make navigation even easier. When the remote is pointed at the screen a cursor follows its movements, allowing deft users to select their target directly. The remote also has a microphone for voice search.

The SJ8500 uses LG's excellent Magic Remote, which is nearly unchanged from that of the UH8500. When the remote is pointed at the screen a cursor follows its movement. The movement of the pointer is very sensitive and takes some getting used to, but it can be used to select menu items directly, without clicking through the whole list. The remote also has a microphone for voice search, which works well. At the center of the navigation pad is a scroll wheel that doubles as the select button, so menu items can be scrolled through quickly with the scroll wheel, then selected by pressing down on it, all without moving your thumb from the wheel.

The webOS remote app has a few useful features, but is missing other common remote app features such as text entry.

Differences between Sizes and Variants

We tested the 55" (55SJ8500) and expect, for the most part, our review to be valid for the other available sizes.

If someone comes across a different type of panel or if their LG SJ8500 doesn't correspond to our review, let us know and we will update the review.

Update 11/27/2017: A reader has informed us that the 65SJ850V in Poland has artifacts when viewed from up close, similar to the SJ9500 (described here). This may make it slightly less suitable for use as a PC monitor, but is unlikely to affect other uses.

Compared to other TVs

Top left: Vizio P Series 2016 (P65-C1). Bottom left: Sony X800E (XBR43X800E). Middle: LG SJ8500 (55SJ8500). Top right: Sony X900E (XBR55X900E). Bottom right: Samsung MU9000 (UN55MU9000).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The SJ8500 is a good LED TV, but it is quite expensive for the performance it delivers. Most of the time, you will be better off with a competing TV in its price range. See our recommendations for the best budget TVs and the best smart TVs.

If you've got a room with wide seating and many windows, then the LG SJ8500 is a better choice, but for a dark room with seating directly in front, then the Samsung MU8000 is better. The LG SJ8500 has better reflection handling and better viewing angles, which is good if you watch TV shows. The LG SJ8500 also has a somewhat better input lag that makes it very responsive for video games. The Samsung MU8000 has better contrast and better black uniformity that offers deep blacks when watching HDR movies in a dark room. Also, the Samsung MU8000 has a bit better SDR peak brightness and slightly better gray uniformity.

LG SK8000

The LG SK8000 is a bit better than the LG SJ8500. The LG SK8000 has a faster response time, so the image is crisper and the fast-moving objects have less blur trail. It also has an optional black frame insertion feature that allows it to make the image even crisper.

Samsung NU8000

If you watch TV in a dark room with seating directly in front, then the Samsung NU8000 is a better choice than the LG SJ8500. It has significantly better black uniformity and contrast that allow it to display deep blacks thus improving picture quality. The Samsung NU8000 also has better SDR peak brightness, which is good for TV shows in brighter rooms. When it comes to gaming, the Samsung NU8000 has a better response time, it incorporates the FreeSync VRR technology, and has slightly better black frame insertion (BFI) to sharpen the image. On the other hand, the LG SJ8500 has somewhat better viewing angles, suitable for wide seating and better reflection handling for those rooms with a lot of windows.

LG SJ9500

The LG SJ9500 is somewhat better than the LG SJ8500. The LG SJ9500 has better SDR peak brightness, which is important when you watch TV shows in a bright room. Also, the LG SJ9500 has a slightly better gradient and better black uniformity for HDR, which is great when you watch HDR content. The LG SJ8500, however, has lower input lag when you play HDR games, and better 4k input picture as its pixel dimming algorithm doesn't display the artifacts shown on the single color areas of the LG SJ9500.

Sony X900E

The LG SJ8500 has slightly better viewing angles than the Sony X900E, and this is great if you have wide seating arrangements. The LG SJ8500 also has somewhat better inputs for use as a PC monitor and a bit better input lag, which makes it very responsive if you play video games. On the other hand, the Sony X900E has much better contrast and local dimming and better black uniformity that allows it to display deep blacks and improve picture quality if you watch movies or HDR movies in a dark room. Finally, the Sony X900E has better SDR peak brightness and can easily overcome glare which is great for watching TV shows in brighter rooms.

7.5 Mixed Usage

Good TV for a mixed usage. The SJ8500 is pretty versatile and has some decent picture quality. Its wide viewing angle makes it a good choice if you have viewing positions to the sides of the TV.

6.6 Movies

Mediocre TV for movies in a dark room. The SJ8500 suffers from important black uniformity issues causing dark scenes to have pale blotches and a dirty look. The blacks themselves also aren't very deep and look gray in a darker viewing environment.
