The LG UF9500 UHD TV is LG's flagship 4k LED TV. Despite its plethora of features, the image quality is sub-par, especially when watched in the dark. For a well-lit, wide living room with seating on the sides, it will still fit the bill, and most will enjoy its good smart functions.

Curved : No

The LG UF9500 looks high-end with its particular stand. The TV is very slim on the upper portion, and although the middle and bottom portions are a bit thicker, it still manages to look sharp overall. Like some other recent TVs from LG, its back is all white, which is something to keep in mind if the TV won't be close to a wall.


The plastic stand mimics the look of stainless steel convincingly. It is very wide, but its footprint is a little shorter than it appears. Total dimensions of the stand for the 65" TV size: 44.9" x 9.6". Footprint: 37.8" x 9.3".

Borders : 0.55" (1.4 cm)

Max Thickness : 1.22" (3.1 cm)


Picture Quality

Because of its low contrast (and the resulting poor blacks), movies on the LG UF9500 won't look as good as on some other TVs. This is especially true in a dark room, where the UF9500's blacks will look gray. This won't be much of a problem if most of your viewing is done in a well-lit room.

5.8 Contrast
Native Contrast
889 : 1

Black will appear gray in a dark room, which isn't ideal.

3.0 Local Dimming
Local Dimming

The local dimming zones are too big to provide a real improvement to the picture. In our test, when the dot is moving fast, the middle zones don't appear to light up anymore. Only the left and right edges of the screen lit up (almost half of the screen lit up for each side).

This TV isn't able to bring highlights very bright.

5.1 Gray Uniformity
50% Std. Dev.
7.717 %
50% DSE
0.249 %

Uniformity is particularly bad. In fact, it is the worst we have seen to date. Edges of the screen are very dark and banding can be seen in middle of the screen on most content. It is especially distracting for sports on long camera pans over playing surfaces. For example, in football, long passes where the camera travels from one end of the field to the other will reveal the 'dirty screen effect' (DSE).

Like other TVs that have IPS panels, the LG UF9500 has a great viewing angle. Watching from the sides won't degrade picture quality as much as most other LED TVs with VA panels.

Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.

4.5 Black Uniformity

All-black screens are cloudy looking. Some flashlighting (light leakage) can be seen on the top left and bottom right of the screen. Massaging the screen with a soft cloth didn't help.

Colors were off by default, but an untrained eye may not notice the problems.

9.7 Post Calibration
White Balance dE
Color dE

Calibration was hard to achieve, and we had to lower contrast to correct the more pronounced gamma issues. Our settings then give a less-bright picture, with lower contrast than what the TV can do by default. It was a sacrifice that has to be made to get the grayscale close to gamma 2.2.

8.0 480p Input

DVDs and standard TV content look great once upscaled on this set.

8.0 720p Input

Cable TV will also look good when upscaled.

9.0 1080p Input

Blu-rays looks sharp without any issues.

10 4k Input

Native 4k content looks very good.

The LG UF9500 can display a wide range of colors when 'Color Gamut' is set to 'Wide'. On normal contents, this option will result in over-saturated colors.

7.0 Reflections

Screen Finish

It reflects slightly more light than average, but there are no rainbows around bright objects.
Maximum brightness of the UF9500 is average.

Passive 3D is comfortable to watch but there is a bit of crosstalk, as you can see on the left side of our logo.



The LG UF9500 will keep up with fast action in sports. Players moving at full speed will stay defined enough that you won't miss any important play. Unfortunately, the screen uniformity is very bad. The screen might appear dirty when the camera is looking at playing surfaces.

8.8 Motion Blur
Response Time
10.0 ms
7.2 ms

The response time is fast, so moving sequences will stay defined. The trail following the logo has some length, but is faint enough not to be bothering. Most of the transitions have overshoot, but it isn't apparent in our moving logo test.

Judder-free 24p via 60i

24p sources like Blu-ray will look smooth, without judder. You can only get rid of judder on 60p and 60i by using motion interpolation, which adds the soap opera effect.

Gaming on the LG UF9500 is great. Controls are responsive under game mode, and the low amount of blur makes everything clearer. Games that require fast reflexes, like first person shooters, will be good on this TV.

127.6 ms
1080p @ 60Hz Outside Game Mode

1080p @ 60Hz @ 4:4:4
36.1 ms

It isn't the fastest TV around but you most likely won't complain about responsiveness. Controls will feel good for all kinds of games. Motion interpolation isn't recommended while gaming, because it increases the input lag too much.

8.0 Supported Resolutions
1080p @ 60Hz @ 4:4:4
1080p @ 120Hz
4k @ 30Hz @ 4:4:4
4k @ 60Hz
4k @ 60Hz @ 4:4:4

Most PC inputs are compatible, except for 1080p @ 120Hz. For all supported modes, chroma 4:4:4 can be enabled for sharp-looking text. To enable, change the input icon to PC. While in 4k, 'HDMI ULTRA HD Deep Color' must also be turned on. Under PC mode, the input lag is the same as in game mode as long as the 'Game' picture mode stays selected.

Sound Quality

Although we noticed some irregularities with the sound of the LG UF9500, the problems shouldn't be noticeable outside our test environment. The LG UF9500 outperforms the sound of most TVs, and has relatively good bass and maximum volume, without much distortion. Another external dedicated sound option would still be better, but for those who want to use the TV speakers, the sound of this TV will be fine.

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.

Very good low-end extension and good maximum loudness. The frequency response is decent too, except under maximum load, where pumping may be present.

6.1 Total Harmonic Distortion
Distortion @ 70
Distortion @ 80
Distortion @ Max

Very good distortion results overall. We did, however, experience some strange behavior (clicks and pops) with our unit. It happens only at high frequencies, with the volume on the TV set to 25 and lower (see the spikes above 3 KHz on the blue line). The problem seems to go away when the volume is increased above 25. This issue may not be audible under regular use, but it was quite audible and reproducible with our test signal.


Smart Features

Smart OS : WebOS

WebOS 2.0 is the smart platform running on the LG UF9500 and it offers a very good interface. It could have been better with more apps, but the most popular ones are there. Combined with the great interface, the magic remote makes everything easy to navigate and can act as a universal remote for your other connected devices, such as a cable box and receivers. Switching inputs feels like using apps, which is great.

The magic remote included with the LG UF9500 has numbers on it and more buttons compared to last year's model. It makes navigation even better.

7.1 Mixed Usage

The LG UF9500 is the flagship 4k LED TV from LG. Feature-rich, it still struggles with picture quality because of its low contrast and grayish blacks. It will shine in a well-lit room, and when viewed from the side, but even then, sports fans might be disappointed by the poor screen uniformity. Gamers will enjoy its motion handling and responsiveness, though. As for movie lovers or people that like to watch TV in the dark, they will be happier with a different, and probably even cheaper TV.
