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.

Our Verdict

7.5 Mixed Usage

Good TV for a wide range of usages. Best suited for a bright room with wide seating. Low native contrast ratio but image remains accurate when viewed at an angle. Average for watching movies in a dark room.

Pros
  • Picture remains accurate when viewed at an angle
  • WebOS smart platform works well
Cons
  • Poor dark scene performance
  • Peak brightness is below average
7.3 Movies

Average for watching movies in a dark room. Poor dark scene performance due to low native contrast ratio and poor local dimming.

7.7 TV Shows

Good for watching TV in a bright room. When viewed at an angle, picture remains accurate. Whole screen gets quite bright to combat glare. Handles reflections well. WebOS smart platform works well for casual watching.

7.4 Sports

Good sports performance. Picture quality is good, and is retained when viewed at an angle. Uniformity is below average resulting in some dirty screen effect. Motion blur is better than average.

7.7 Video Games

Good for gamers. Picture quality is good. Motion handling is better than average, but a short trail may be seen following fast movement. SDR input lag is low, which is good.

8.1 HDR Movies

Good HDR performance. Supports HDR10 and Dolby Vision. Can produce a wide range of saturated colors. Unfortunately the local dimming doesn't work well to brighten highlights. Dark scene performance is poor.

7.5 HDR Gaming

Average for HDR gaming. Supports a wide color gamut and 10 bit gradient. Input lag in HDR is quite high. Can't get bright highlights.

7.0 PC Monitor

Good for a PC monitor. Input lag is low, and supports a wide range of resolutions. Motion blur is better than average. Supports chroma subsampling for clear text across all backgrounds.

Test Results

9.5
Design
Style
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.

Design
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"

Design
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.

Design
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.

Design
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.

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.

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 UH9500 SDR peak brightness is average. The local dimming dim too much the smaller highlights, making the overall score just average. Highlights 10% and bigger are brighter and are good for SDR though.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
