8.5

Design

Curved : No

The LG UF8500 looks like a high-end TV. The borders are thin and the TV is slim. The stand is very wide, but the TV rocks back and forth when you push it.

Picture Quality

The overall picture quality for movies is sub par. Dark scenes get washed out by the poor and non-uniform blacks. The passive 3D is good, though.

5.6 Contrast
Native Contrast
:
798 : 1

It has an IPS panel, so the blacks are poor.

3.0 Local Dimming

Yes
Backlight

Similar to the LG UF7700, the local dimming is a bit useless. The zones are really big.

6.2 Gray Uniformity
50% Std. Dev.
:
3.256 %
50% DSE
:
0.249 %

The gray uniformity is bad. The corners and the edges are darker than the rest. There are also a lot of darker lines and spots everywhere.

6.5 Viewing Angle
LCD Type
:
IPS
Color Shift
:
24 °
Brightness
:
36 °
Black Level
:
75 °

Due to its IPS panel, it maintains its color accuracy even when viewed at an angle.

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.

0 Black Uniformity
Native Std. Dev.
:
5.975 %

Like every other LG IPS TV that we have reviewed, the black uniformity is bad. The corners are brighter than the rest. We tried fixing the issues by rubbing the screen with a soft cloth, but we couldn't make it better.

DVDs looks good on this TV once upscaled.

Blu-rays looks great without any issues.

Native 4k content looks very sharp.

7.0 Reflections
Reflection
:

Screen Finish
:
Semi-gloss

Its semi-gloss finish reflects more light than average. At least the direct reflections only have a small rainbow around them.
The maximum luminosity, when increasing 'Backlight' to the max, is average-good.

10 3D
3D
:
Yes
3D Type
:
Passive

The passive 3D is great, with no crosstalk at all (assuming you sit relatively in-axis).

Motion

While the motion blur is rather good, this isn't a great TV with which to watch sports, because the uniformity of the screen is bad. On panning shots when watching sports, you can see darker spots and lines on the field.

8.2 Motion Blur
Response Time
:
16.0 ms
Overshoot
:
0 ms

The response time is average-good. All transitions take about the same time, which results in a darker outline following and leading moving objects. The backlight isn't flicker-free; it uses a PWM, even at maximum brightness.

It can play 24p movies judder-free, except when they are transmitted over 60p. 'TruMotion' is the soap opera effect feature.

Inputs

This isn't a particularly great TV for playing video games, due to the rather high input lag.

6.0 Input Lag
1080p @ 60Hz
:
56.7 ms
1080p With Interpolation
:
116.5 ms
1080p @ 60Hz Outside Game Mode
:
63.1 ms
4k @ 60Hz + HDR
:
N/A
4k @ 60Hz @ 4:4:4 + 8 bit HDR
:
N/A

The input lag varies a lot, but all modes are about the same, so you don't need to be under 'Game', as long as you turn off 'TruMotion'.

8.0 Supported Resolutions
1080p @ 60Hz @ 4:4:4

No
4k @ 30Hz @ 4:4:4
:
Yes
4k @ 60Hz
:
Yes
4k @ 60Hz @ 4:4:4
:
Yes

It doesn't support 1080p @ 120 fps, but it does support chroma 4:4:4 if you label the input as PC. To get 4k @ 60hz @ 4:4:4, you will also need to turn on 'HDMI Ultra HD Deep Color'.

Sound Quality

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.

7.2 Frequency Response
Std. Dev. @ 70
:
4.66 dB SPL
Std. Dev. @ 80
:
3.80 dB SPL
Std. Dev. @ Max
:
4.45 dB SPL
Max
:
85.2 dB SPL
Low-end Cutoff
:
84 Hz

Good bass response for a TV, and the frequency response is good, too. But the TV doesn't get loud at all.

3.7 Total Harmonic Distortion
Distortion @ 70
:
0.050
Distortion @ 80
:
0.612
Distortion @ Max
:
1.144

Good distortion values at low volumes, but poor results when under heavier loads, even though the TV doesn't get loud.

6.6 Mixed Usage
The LG UF8500 LED TV is basically the same as the cheaper UF7700, but with 3D. Overall, the picture quality is not very good. At least it maintains its colors at an angle and has great smart features.
