The LG SJ9500 is a high-end 4k LED TV with a wide viewing angle thanks to its use of an IPS-type LCD. Its input lag is low for gaming, and its WebOS smart features are very intuitive. It has a decent overall picture quality and a better than average brightness, but its low contrast and non-uniform blacks make it less suitable in a dark room.

LG SJ9500 Design Picture
Curved : No

The design of the LG SJ9500 is excellent. The TV looks great, with an interesting curved stand and premium feel. The TV is thin, so looks good when wall mounted. There is some basic cable management down the rear of the stand, and most of the inputs are easy to access if placed close to a wall.

Stand

The stand is curved and looks good. It is made of metal and feels high quality. It also supports the TV well and feels stable.

Footprint of the 65" TV stand: 11.4" x 31.6"

Back

Wall Mount : Vesa 300x200

The rear of the TV is very similar to the UH9500 of 2016, with a brushed metal finish and the same input locations. Most of the inputs are out the side of the TV and easy to access if wall mounted.

Borders

Picture Quality

The LG SJ9500 LED TV has a better than average picture quality. When set in a dark room, the ordinary contrast ratio tends to make blacks to look more grayish than really deep blacks, giving dark scenes a washed out look. When set in a bright environment, the SJ9500 fares much better, as the low contrast ratio effects are less apparent and also because it has a very good SDR peak brightness and good reflective capacity, which can fight glare and deals with reflections pretty well. The gray uniformity is below average and unfortunately for sports fans, some dirty screen effect is visible. On the other hand, the viewing angle is passable, which means it can be a good TV for big sports event gathering, as people, no matter where they are sitting, are going to have a similar picture quality. Finally, HDR could be better even if it as a great wide color gamut, as the HDR peak brightness is ordinary and the local dimming is awful.

The LG SJ9500 contrast ratio could be better, but it is fairly decent for an IPS TV, which tends to have a lower contrast ration than VA TVs. With a contrast ratio of around 1500:1, when set in a dark room, blacks won't be very deep and will look grayer than really black and dark scenes will look a bit washed out.

Fortunately, if the TV is set in a room with moderate lighting, the effect of a low contrast ratio is less noticeable, and for this reason, the LG SJ9500 is better suited for this kind of room environment.

Edge

The local dimming on the SJ9500 is bad and is very similar to the local dimming of the 2016 UH9500. The local dimming of the SJ9500 is implemented on vertical zones, and it is clearly visible in our video, as large vertical blooming follow the moving highlight, leaving the rest of the screen darker.

Another issue also shows up in our video, and it is the darkening of the smaller highlight, which is a problem, as the local dimming should not darken the highlight, since this may ruin the HDR effect of movie, where the highlight is supposed to be very bright in comparison to the rest of the screen.

Since the local dimming is really bad, we suggest to turn it off, or at least maybe set it to low or medium instead of the maximum setting, so that the negative effects are less apparent.

Plot over time

Good SDR peak brightness, good enough even for a bright room. Unfortunately, the TV's local dimming makes dark scenes even darker by dimming everything, including the highlights, because the local dimming isn't granular enough. Overall, the TV isn't quite as bright as last year's UH9500, and falls behind many of its current competitors like the Sony X930E and the Samsung MU9000.

Plot over time

Decent HDR peak brightness. The TV's crude local dimming still does manage to make highlights brighter in dark scenes, as shown in our smaller window tests, at the cost of noticeable blooming. However, our real scene brightness test shows that highlights in most HDR scenes won't be shown nearly as bright as the intended 1000 or 4000 cd/m². This is in contrast to last year's LG UH9500, which had a much brighter real scene test but actually dimmed highlights in dark scenes. Overall, the brightness is quite behind competing Sony TVs like the X930E and a little behind the Samsung MU9000 and MU8000. If users find HDR content too dim, turning up the 'Dynamic Contrast' setting will make most of the scene brighter, although it won't affect the extreme highlights.

Mediocre viewing angle; fairly typical for a TV with an IPS panel, far better than most TVs with VA panels, but far worse than TVs with OLED panels. The black level remains constant which is great, but the brightness and colors degrade significantly when the TV is viewed at moderate angles. Still, this TV is a good fit for a room where people often sit to the side of the TV and view it at an angle.

The black uniformity of the SJ9500 is poor. When the local dimming is completely turned off, some flashlighting can be seen near each corner and some inequality covering the upper part of the screen.

When the local dimming is set to maximum, the black uniformity is greatly affected. Since the local dimming is implemented over vertical zones, covering the totality of the screen, when our black uniformity test image is displayed, a large blooming zone is visible near the center cross of the image, leaving both sides completely dark. This show very well the limitation of the local dimming of the SJ9500.

The SJ9500 gradient performance is excellent, as it can display our image without much banding. Some little irregularities are visible in the darker shade, but we did not notice problematic banding while watching movies.

Out of the box, when set on the most accurate picture setting ('ISF Expert Dark Room', 'gamma BT.1886', and 'Warm1' color temperature), the overall accuracy is decent. With a white balance dE of 3.44, most enthusiasts could notice the inaccuracy. The color accuracy is a bit better, as a color dE of 2.43 should only be noticeable by professionals who regularly work with calibrated TV. As for the gamma, 2.24 is not far from our desired target, but the curve is not really flat, with a small dip in the darker and brighter end.

For most people who will not calibrate their TV, those setting should be used, as it is with those settings that we measured the best accuracy, but note that it differs slightly from what we measured before from other LG TVs, on which the gamma 2.2 setting with the Warm2 color temperature usually give us a better result.

After calibration, the accuracy is excellent. The white balance was corrected to have a dE of only 0.11, which is excellent and almost not noticeable for anyone. The color accuracy was also improved, to have at the end a dE of only 1.12 which is almost at the limit where it becomes not noticeable (1.00). As for the gamma, only the very small errors in the lower IRE could not be corrected, but this is really not a problem, as the rest of the curve is very good and follow our target of 2.2 very closely.

LG SJ9500 EOTF

Great wide color gamut, among the best of 2017. Saturated colors in HDR content will be well represented. The TV's accuracy at showing intermediate colors is decent but not the best, as some colors like cyan and magenta don't follow their target lines, and fully saturated cyan turns green.

The TV's HDR EOTF in the Cinema and Technicolor picture modes follows the target PQ curve beautifully when LG's 'Active HDR' is enabled by setting 'Dynamic Contrast' to 'Low'. Turning 'Dynamic Contrast' up higher will make scenes even brighter, at the cost of picture accuracy, though it may be worth the cost when watching HDR in a bright room. The EOTFs in 'Game' mode and 'PC' mode also follow the PQ curve well, although 'Active HDR' isn't available in those modes.

The SJ9500 has an excellent result on our image retention test, which is much better than the 2017 UH9500. Note that on our test picture image, some really faint remnants of the Rtings logos are visible, but it was not enough to trigger a response from our image analysis software. When viewed in person, it was not really visible and it is also good to note that the camera does pick up a bit more detail than the human eyes.

Motion looks great on the LG SJ9500. It has low motion blur due to a fast pixel response time, it can remove judder from nearly any 24p movie source, and it can use the soap opera effect to interpolate content to 120 fps for even smoother motion. Its one flaw is its backlight flicker, which is always present and becomes worse at lower backlight settings.

Great pixel response time, good enough for watching fast-moving content. Most of the blur in the picture is due to backlight flicker and persistence. There is still a short trail of response time blur following our moving logo, though, fortunately, it's very faint. There is a tiny bit of overshoot visible in the response time plots but it shouldn't be visible in person.

The TV, unfortunately, only dims the backlight by using PWM, and PWM is even visible when the brightness is at maximum. This means that the TV will always have 120 Hz flicker, and this flicker will become even worse at lower backlight settings. While this flicker does reduce persistence blur, it also adds double image artifacts as seen in the photo in the motion blur section, which is worse than persistence blur. The TV also lacks a black frame insertion setting to reduce the flicker frequency to avoid double image artifacts.

To remove judder from 24p movies from 24p sources, the 'RealCinema' option needs to be turned on and the 'TruMotion' option set to 'User' with both sliders ('De-Judder' and 'De-Blur') set to 0, and it won't add soap opera effect.

The TV can use the soap opera effect to interpolate lower frame rate content up to 120 fps, which makes motion look much smoother. Unfortunately, there are visible artifacts when interpolating <60 Hz content and the backlight isn't synchronized to the panel so blur is even present when interpolating 60 fps content.

Outstanding low input lag, low enough to please nearly any gamer. Normally, only the 'Game' picture mode has low input lag, but in 'PC' mode all picture modes have low input lag. 4:4:4 color is only shown properly in PC mode, but this is usually only a concern for PC use anyway. Overall, the input lag is one of the best we've tested in 2017; a little better than most Samsung TVs and LG's own OLEDs, and much better than most Sony TVs.

Decent frequency response. The SJ9500 tracks our target quite well and offers a room correction feature that calibrates the TV's sound output to reduce the effects of the room's acoustic properties. Its low-frequency extension is better than average, but it does have a significant amount of dynamic range compression at higher volumes.

Poor distortion performance. While THD is quite low even at maximum volume, the SJ9500 produces a lot of IMD at higher levels, possibly due to the compression algorithms used as well as the aliasing present at higher frequencies. This is notably different from LG SJ8500.

The SJ9500 runs LG's WebOS smart interface, which is fast to navigate, has lots of apps and has a great remote. The interface is split into three sections: apps, settings and inputs, each with its own button the remote, quick menu and full menu. This structure makes the interface quick to navigate but it may be confusing to first-time users. The TV's smart remote is one of the best and has a pointer that follows its movement like a Nintendo Wii remote, which lets users select menu items directly and saves time.

The WebOS interface is split into three parts: settings, inputs, and apps. Each has its own button on the remote, quick menu and full menu. The quick menus list some commonly used items to save time, while the full menus give a wealth of deeper options. This split layout makes the interface quick to navigate, but it can be confusing for first-time users.

The SJ9500 comes with LG's excellent Magic Remote, which has some useful smart features and clever design touches. Although the remote is large, it isn't too heavy, and the remote's underside is contoured so the thick lower section fills your hand, while the upper section is thin and light, making the remote very ergonomic. The remote's standout feature is its pointer, which causes a cursor on the screen to follow the remote's movement like a Nintendo Wii remote. This allows users to select menu items directly, which saves time. The remote also has a microphone for voice search, but it can only search for content and apps or search the internet.

Bottom right: Sony X900E (XBR55X900E).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The SJ9500 is a good TV overall, but its picture quality doesn't hold up to the competition in its price range.

Samsung MU9000
55" 65" 75"

The MU9000 is a mid-range 4k LED TV from Samsung which features a better than average screen finish to combat daytime reflections making it one of the best TVs to use in a bright room. Overall, it offers better picture quality than the LG and more versatility. Unless you need the wider viewing angles found on the SJ9500, the MU9000 is a better choice.

LG C7
55" 65"

The LG C7 is an entry-level 4k OLED TV with exceptional picture quality in a dark room and great general performance. It's a bit more expensive for its size than the LG SJ9500, but it is significantly better in almost every aspect. If you can afford the bump in price or don't mind getting a smaller TV, the LG C7 is a clear winner.

Vizio P Series 2017
55" 65" 75"

Vizio's 2017 P Series 4k LED TV is their highest-end model and offers great picture quality in a dark room thanks to its advanced local dimming feature. It doesn't have the wide viewing angle so it doesn't have as much flexibility with placement as the LG, but it offers significantly better picture quality. Since it's also usually the cheaper choice of the two, most people should buy it over the SJ9500.

Sony X900E
49" 55" 65" 75"

The Sony X900E 4k Android TV is a mid-range LED TV with a versatile set of features and great picture quality. It has a slightly higher input lag than the LG SJ9500, its smart features are a little more sluggish, and it doesn't have a wide viewing, but it trumps the LG in almost all of our other tests and a better performer overall. Since they're usually around the same price, the Sony should be most people's choice over the LG.

7.5Mixed Usage
Show Help
What it is General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
The LG SJ9500 is a good TV for a mixed usage. It has a decent picture quality in most environments, and its wide viewing angle makes it easy to find a good viewing position. Unfortunately, its poor blacks cause its picture quality to be less than stellar in a dark room.
6.8Movies
Show Help
What it is Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
Average TV for watching movies in a dark room. The LJ SJ9500's picture quality in a darker environment is negatively impacted by its low contrast and uneven blacks that can show distracting clouding in letterboxes and make the image look a bit flat. Its local dimming is also better kept off as it.

Score components:
The LG SJ9500 is a very good choice for watching TV shows in a bright room. It gets bright enough to combat most reflections, and its smart features are some of the best available today making it easy to access streaming services.
7.3Sports
Show Help
What it is Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
Score components:
Decent TV for watching Sport. The SJ9500's wide viewing angle makes it easy to share with a larger group of friends. Its screen, however, isn't the most uniform, and some uniformly colored sports fields might show banding or other blotches.
8.1Video Games
Show Help
What it is Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
Great TV for playing video games. The SJ9500's impressively low input lag makes it very responsive to button presses keeping the experience seamless. It also produces a low amount of motion blur, so fast-paced games with lots of movement on screen looks clear and sharp.
7.0HDR Movies
Show Help
What it is HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Average HDR performance. While the SJ9500 is capable of reproducing a wide gamut of colors and 10 bits of color depth, its mediocre contrast and low HDR peak brightness mean it won't offer a significant visual benefit over normal SDR content.
7.8HDR Gaming

What it is HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
Good HDR gaming TV. While its HDR capabilities are somewhat lackluster, the SJ9500's input lag and overall gaming performance aren't hindered by an HDR input.
8.0PC Monitor
Show Help
What it is PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Great TV to use as a PC monitor. The SJ9500 supports all the essential resolutions, including Chroma 4:4:4, but it's also one of the rare TVs to also support a 1080p@120hz input. Combined with a very low input lag and low motion blur, it makes for a very suitable monitor. Some users, however, might find horizontally alternating stripes of the screen to be a little distracting.
