This tv was replaced by the LG SJ9500

Type : LED
Resolution : 4k
Refresh Rate : 120 Hz

The LG UH9500 is a high end 4k LCD TV offered by LG. It is only available in large sizes, and has pretty good picture quality. When viewed at an angle, the image keeps its contrast and color which is great. Unfortunately the dark room performance is poor due to the low native contrast ratio, and the motion handling could be better.

9.5

Design

Curved : No

The UH9500 has a sleek design, which is very similar to the slightly lower model LG UH8500. The biggest notable difference is the thinness of the top 2/3 of the screen. Unfortunately for a large TV the center stand doesn't provide as much support as the dual supports on the cheaper LG models.

Stand

The stand is made of stainless steel, and looks great. Unfortunately it feels a bit wobbly with only center support.

Footprint of the 65" TV stand: 11.2" x 38.3"

Back
Wall Mount : VESA 300x200

The back looks good, with a brushed metal finish. This is the biggest difference when compared to the slightly bulkier UH8500. The stand also includes a hollow area for cable management. If wall mounted some of the inputs may be difficult to access.

Borders
Borders : 0.63" (1.6 cm)

The borders are quite thin, and have a metal surround. There is a black space before the image begins.

Thickness
Max Thickness : 2.09" (5.3 cm)

The TV is extremely thin for the top 2/3, and even at the widest point where the inputs are it is thinner than average. This looks very similar to the LG B6.

7.5

Picture Quality

The UH9500 provides good picture quality in a brighter room, but unfortunately can't get deep blacks to improve dark scene performance. It is limited by the low native contrast ratio. Although it has local dimming, it doesn't work well enough to improve dark scenes. Like most LED TVs it has poor gray uniformity. The wide color gamut and 10 bit panel are very good for HDR content, and when viewed at an angle the picture quality is retained well.

6.3 Contrast
Native Contrast
:
1180 : 1

The contrast ratio is below average, which is to be expected from an IPS TV. In a dark room the blacks appear gray, but for a brighter room this is not an issue.

3.0 Local Dimming
Local Dimming
:
Yes
Backlight
:
Edge

The UH9500 is an edge lit TV that features local dimming. Like most edge lit TVs, the local dimming is not as effective as some other full-array LED TVs. Blooming can be seen in large vertical bands where small highlights are situated.

When set on 'High', the smaller highlights in the video can be seen getting darker and brighter every time a zone gets turned on and off. We recommend that you set it on a lower setting if you notice this behavior when playing video games, or when watching normal TV shows and movies.

The peak brightness is below average. These measurements are consistently lower than the lower end UH8500, which is a bit surprising. Although the whole screen can get quite bright, the local dimming significantly reduces the peak brightness of smaller windows. This test is performed with a HDR10 signal.

6.4 Gray Uniformity
50% Std. Dev.
:
3.256 %
50% DSE
:
0.239 %

The gray uniformity is below average for the LG UH9500. A multitude of vertical bands can be seen throughout the screen. Also, the color on the right side of the screen is also a lot warmer. Dirty screen effect is visible when watching sport or any other media with large panning shots over a uniform color surface.

6.4 Viewing Angle
LCD Type
:
IPS
Color Shift
:
24 °
Brightness
:
34 °
Black Level
:

When viewed at an angle, the contrast decreases a little bit but the colors remain quite accurate. This is about the same result as the LG UH8500 which is good for an LED TV.

7.6 Black Uniformity
Native Std. Dev.
:
1.749 %

The black uniformity of the UH9500 is good. Like most IPS TVs, some clouding can be seen on our test picture, but luckily it is very hard to notice when watching normal content.

9.5 Gradient
Color Depth
:
10 Bit

The LG UH9500 can display a 10 bit gradient pretty well. There are no particular banding or shade problems when analyzing our test picture.

8.1 Pre Calibration
White Balance dE
:

Prior to calibration, the results are quite good. The white balance is a little bit off, but this should not be an issue for most people.

9.7 Post Calibration
White Balance dE
:
0.23
Color dE
:
0.85
Gamma
:
2.21

Calibration is performed with the 2 and 20 point system on the TV. It works well to remove small errors in the white balance. Even with the color space settings, the blue was undersaturated. You can see our recommended settings here.

8.0 480p Input

As with other LG TVs, upscaling of low quality content is good. Some halo effect can be seen along straight edges, but overall a good result.

8.0 720p Input

Upscaling of 720p content is good, and details are preserved well. Image remains sharp.

9.0 1080p Input

1080p content such as blurays appear crisp and clear.

10 4k Input

Content at native 4k resolution looks very good. No issues can be seen.

The LG UH9500 do have some image retention, but the retention is present only right after the static scene of the test video. After 2 minutes of recovery, the LED screen is back to normal, without any image retention at all. When compare to others LG high end LED TVs like the UH8500, this is much better and should not be too much a annoyance when watching normal TV content.

7.5 Reflections
Reflection
:
1.9 %
Screen Finish
:
Semi-gloss

The higher end UH9500 has a slightly more glossy screen than the UH8500, but it is still semi-gloss. It should be fine for a room with a few windows. Some faint rainbowing can be seen around direct reflections.

9.0 3D
3D
:
Yes
3D Type
:
Passive
2D to 3D
:
Yes

The TV supports passive 3D which means that although there is no noticeable flicker, the number of lines of horizontal resolution is decreased. Due to the size of the TV, this can be noticeable from up close. There is a little bit of crosstalk visible when viewing off-axis.

7.3

Motion

Although the motion blur is better than average, fast movement isn't as clear as some other TVs. The LG UH8500 which is the model below actually has a shorter trail following moving objects, but this still shouldn't be an issue for most people. The UH9500 has a 120Hz panel which is able to interpolate lower frame rate content, so those who like the soap opera effect will be happy. Movies watched on a bluray player appear smooth.

7.4 Motion Blur
Response Time
:
20.0 ms
Overshoot
:
0 ms

The motion blur is better than average, but noticeable worse than the slightly lower model LG UH8500. This shouldn't be an issue for most people, however. The backlight uses PWM flicker to dim, and so duplicating images can be seen behind the logo.

Judder-free 24p via 60i
:
No

Movies playing from DVDs, Blu-rays or from streaming apps play without judder when the 'Real Cinema' option is turned on. Movies playing from 60p/60i sources like cable/satellite/set-up boxes or a computer do have some judder. For most people this is not an issue.

Judder can be removed by setting 'TruMotion' to 'User' and setting 'De-Judder' to a low value. Note that even at a low value, it will introduce a bit of soap opera effect.

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

The UH9500 has a 120Hz panel, and is able to interpolate lower frame rate content. For those that enjoy the soap opera effect, enable motion interpolation with the 'TruMotion' setting.

8.1

Inputs

The LG UH9500 has good input lag and can accept most of the usual PC resolutions. Traditional gamers will find it responsive enough for fast paced games. HDR gaming is a bit less responsive, but will still be good enough for the casual gamers out there. When used as a PC monitor, it will still be a good choice, since it can easily display the most demanding resolutions with maximum details without any problems.

Input lag is good for SDR content, but more competitive gamers may notice a slightly delay when playing HDR games. For most people, this should not be an issue.

Update 12/08/2016: With the newest firmware update (04.30.19) there has been the addition of a HDR gaming mode. In this mode the HDR input lag is lower, and should be fine for HDR gaming. Note that although the TV accepts a 4k @ 60Hz @ 4:4:4 + HDR signal, it can't accurately display the chroma subsampling in any HDR mode, even with the 'PC' icon selected.

8.0 Supported Resolutions

To enable chroma subsampling support, change the input icon to 'PC'. It is also necessary to enable 'HDMI ULTRA HD Deep Color' in the 'General' settings menu to allow 4k @ 60Hz @ 4:4:4. Although it has a 120Hz panel, like other LG TVs it is not able to support a 120 fps input.

Sound Quality

Average sound performance from the TV speakers. The frequency response is good at lower volumes, but for louder listening has some issues. It also gets loud, which is good. For someone who cares about sound though, a soundbar is an improvement.

Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.

Average performance. Frequency response is good at lower volumes. However, under heavier loads compression and pumping will be present. Additionally, this TV does get quite loud and does produce a decent amount of bass, for a TV.

6.0 Total Harmonic Distortion
Distortion @ 70
:
0.039
Distortion @ 80

Smart Features

Smart OS : WebOS 3.0

The UH9500 features LG's latest iteration of WebOS (3.0). It is very intuitive and easy to use, especially with the included smart remote. It also includes support for popular streaming services such as Netflix and Amazon Video out of the box, with many more applications available from the 'LG Content Store'. It is one of the most stable smart platforms, and is always fast to navigate or load apps.

Apps

Included with the TV are the most popular apps, such as Spotify, Netflix, Amazon Video and Hulu. It is also possible to download a wide range apps from the 'LG Content Store'.

Differences between Sizes and Variants

We tested the 65" (65UH9500). For the most part, we expect our review to be valid for the 86" (86UH9500).

If someone comes across a different type of panel or if their LG UH9500 doesn't correspond to our review, let us know and we will update the review.

Compared to other TVs

Top left: Samsung KS8000 (UN55KS8000). Bottom left: LG B6 (OLED55B6P). Middle: LG UH9500 (65UH9500). Top right: Sony X930D (XBR55X930D). Bottom right: LG UH8500 (55UH8500).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The LG UH9500 is a good all-round TV, but can be hard to recommend for those looking at the 65" variant due to its similar performance to the cheaper LG UH8500. In some cases, the LG UH8500 actually performs better due to the lower response time and higher peak brightness. For those interested in the 86" variant there is very little competition and it could be a good choice depending on your usage. Keep this in mind when viewing our recommendations below.
