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.
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.
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.
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.
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.
Picture quality is good. Handles fast motion quite well with some blur. Input lag is quite high, which is bad.
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.
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.
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.
We tested the 65" (65UH5500). For the most part, we expect our review to be valid for the 50" (50UH5500).
If someone comes across a different type of panel or if their LG UH5500 doesn't correspond to our review, let us know and we will update the review.
The LG UH5500 is a budget offering with impressive picture quality, especially for the price. It has especially good dark scene performance, so is hard to beat for those with a dark room. Keep that in mind when viewing our recommendations below.
There is no local dimming feature to improve the dark scene performance of this TV. This video is only for reference.
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.
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.
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.
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.

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.
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.
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.
Decent performance. Frequency response is good and mostly flat at lower volumes. However, there will be pumping and compression present under heavier loads. Additionally, maximum volume and low-end cutoff of are also close to average.
The UH5500 comes pre-loaded with WebOS 3.0. This is the same version of the smart platform found in all of the 2016 LG smart TVs. It is definitely an improvement on the previous generation, and provides an easy to use interface with lots of features. It also has access to loads of apps on the 'LG Content Store' for watching Netflix or Amazon Video, or listening to music on Spotify. Plugging a USB drive into the USB 2.0 port allows watching videos or a slideshow of photos straight from the TV.
The TV includes a basic remote, which is the same as other low-end LG TVs such as the UH6100. It is quite simple to use.
