The LG UH5500 is a budget 4k LED TV with good picture quality, especially in a dark room. It has good motion handling, and deals with reflections well. Unfortunately it isn't all good, as the input lag is considerably higher than the competition and the screen doesn't get very bright.

Our Verdict

7.5 Mixed Usage

Better than average TV for a range of usages. The picture quality is good, especially for watching movies in a dark room. Handles reflections very well, which helps to make up for the low peak brightness in a brighter room. Unfortunately the picture quality degrades when viewed at an angle.

See our Mixed Usage recommendations
7.2 Movies

Slightly above average for watching movies in a dark room. Dark scene performance in very good due to high native contrast and great black uniformity. Unfortunately lacks local dimming feature to improve performance further.

See our Movies recommendations
7.3 TV Shows

Above average for watching TV in a brighter room. Picture quality is good, but degrades when viewed at an angle. Can't get very bright to counteract glare, but screen finish is good at dealing with reflections. Smart platform works well for casual viewing.

See our TV Shows recommendations
7.2 Sports

Good for watching sports. Picture quality is good, but degrades when viewed at an angle. Motion handling is good, with only a little motion blur. Some dirty screen effect is visible in panning shots.

See our Sports recommendations
8.1 Video Games

Picture quality is good. Handles fast motion quite well with some blur. Input lag is quite high, which is bad.

See our Video Games recommendations
7.4 HDR Movies

Average for watching HDR movies in a dark room. Picture quality is good, but doesn't support a wider color gamut or high peak brightness to benefit from HDR. Accepts a HDR10 signal. Doesn't feature local dimming to improve dark scene performance.

See our HDR Movies recommendations
8.0 HDR Gaming

Slightly above average for HDR gaming. Accepts a HDR10 signal, but this doesn't improve the picture quality. Doesn't support a high peak brightness of highlights or wide color gamut. Input lag is quite high which is bad. Motion handling is good.

See our HDR Gaming recommendations
6.8 PC Monitor

Slightly better than average choice for a PC monitor. Fast motion has a little blur which is good. Supports chroma subsampling at the most demanding resolutions, for clear text. Input lag is quite high which is bad. Picture quality is good but degrades when viewed at an angle.

Test Results

Curved No

The design of the TV is very basic, with two wide-set feet and relatively thick borders. It appears quite blocky and definitely won't be the centerpiece of any room. 


The stand is simple, and almost the width of the TV. We had to extend our test table to fit the TV. It supports the TV quite well, but as with any large TV there is some sway.

Footprint of the 65" TV stand: 11.7" x 53.1"

Wall Mount VESA 400x200

To back is very similar to other budget TVs, but provides easy access to all of the inputs even if wall mounted. Note that the 50" model has a VESA 300x200 mount.

Borders 0.75" (1.9 cm)

The borders are thicker than average. They have a reflective plastic which picks up fingerprints easily. The bottom border of the TV has a textured finish which stands out a bit.

Max Thickness 3.31" (8.4 cm)

The TV appears quite bulky, which may be an issue if wall mounted. The widest part of the TV is near the base.

The SDR peak brightness is average and is the same as when the TV is in HDR mode. This makes a TV not the best TV when set in a bright room since, at this level of brightness, it will have a hard time fighting glare.

The TV can't get very bright, and doesn't have local dimming to increase the brightness of highlights. The peak brightness remains the same whether it is a HDR or SDR signal, which is good as some other LG TVs offer limited SDR performance. For a very bright room the TV may not be able to counteract all of the glare.

Picture Quality
Gray Uniformity
50% Std. Dev.
5.429 %
50% DSE
0.244 %

The gray uniformity of the UH5500 is bad. All the sides and corners of the TV are darker. Some lighter horizontal bands and some darker vertical bands can also be seen. Dirty screen effect is visible when watching sports like hockey, football or soccer, where large panning shots over a uniform surface make those darker bands really visible. This is a little less noticeable while watching normal TV shows.

The picture quality declines rapidly when viewed at an angle. Colors lose accuracy and contrast is lost. Despite this, it is a better result than most other cheap VA TVs.

Update: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results.

Picture Quality
Black Uniformity
Native Std. Dev.
0.920 %

The black uniformity is very good on this LG TV. Some faint clouding can be seen on the lower left corner, but nothing really problematic, since it is only noticeable on our test picture. When looking at normal content, no clouding can be seen.

Picture Quality
Color Depth
10 Bit

The TV can display a 10 bit gradient pattern smoothly, without 8 bit gradations. There are some green shade problems in the gray and also in the dark green, but in general the gradation is pretty smooth and without banding.

Picture Quality
Pre Calibration
White Balance dE
Color dE

Prior to calibration, the results are quite good. The gamma is quite high so there may be some black crush. The colors are quite accurate and should be fine for almost anyone. The white balance is a little off, but without a side by side comparison to a calibrated TV it is hard to tell the difference.

Picture Quality
Post Calibration
White Balance dE
Color dE

Calibration is quickly performed with the 20 point system. It responds well to changes, and results in a very accurate image. All minor issues can be fixed, and the gamma is adjusted to the target if 2.2. The color space is a bit less responsive, but it was still possible to bring down the total color dE.

Picture Quality
480p Input

Low quality content such as DVDs look quite good once upscaled. Some halo artifacts can be seen along edges, but this shouldn't be too much of a problem and is typical of LG TVs.

Picture Quality

720p content such as cable TV appears quite clear. Details are preserved well.

Picture Quality

1080p content is upscaled well. The image is clear and sharp.

Screen Finish

The UH5500 has one of the lowest reflection numbers, even when compared to high end TVs. This is great for a room with some bright lights. The semi gloss finish works to diffuse reflections, reducing their intensity.

There is some motion blur, but this will only be an issue with fast paced content. There is a little overshoot which can be seen in the brighter areas following the logo. The PWM flickering backlight can be seen in the duplications following the logo.

To play movies from a 24p source such as a Blu-ray player without judder, turn 'Real Cinema' on. Some judder is always present when playing movies over a 60Hz source, but this isn't an issue as most people don't notice it.

Motion Interpolation

Motion Interpolation (60 fps)

The UH5500 has a 60Hz panel which is able to interpolate lower refresh rate content. This is good for those who enjoy the soap opera effect.

4k @ 60Hz @ 4:4:4 + 8 bit HDR

The input lag is high, so the TV doesn't feel responsive. It is fairly consistent across different picture modes, resolutions and refresh rates, but varies by up to 10ms with each measurement. This is bad for gamers or those looking to use the TV as a PC monitor. The HDR input lag is the same as the SDR input lag.

Update 01/10/2017: The UH5500 just received a new update (04.30.82) that added a new HDR game mode to this TV. The input lag in HDR Game mode is now at 18.5ms. Note that input lag under gamer mode with a 1080p and 4k resolution also got by half, it is now around 25ms.

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

To enable chroma subsampling support, set the input icon to 'PC'. For higher bandwidth signals such as 4k @ 60Hz @ 4:4:4, enable 'HDMI UHD Deep Color' for the HDMI port in 'General' settings. Supports chroma subsampling at a wide range of resolutions for those who are looking to use it as a PC monitor. Like other LG TVs, it doesn't support a 120Hz input.
