The LG UH8500 4k HDR TV doesn't have revolutionary picture quality, but it is still the best LED TV from LG that we have reviewed so far. It even improved on the already great WebOS smart platform, which is a nice bonus. Like other TVs from LG, it's a good pick for a living room with seating on the sides of the TV. Unfortunately, the picture isn't the best in a dark environment.
Good TV for mixed usage. Performs best in a bright room with wide seating as the image remains accurate when viewed from an angle, but blacks appear gray in a dark room.See our Mixed Usage recommendations
Fairly good TV for watching movies. Low native contrast ratio so blacks appear gray in a dark room, and local dimming is poor. Image is very accurate and uniformity is quite good.See our Movies recommendations
Good TV for TV shows in a bright room. Image remains accurate when viewed at an angle, and TV can get decently bright to fight glare. Reflection handling is quite good, and smart platform works well for casual viewing.See our TV Shows recommendations
Good choice for gamers. Best suited to a bright room due to low native contrast ratio. Motion handling is very good, so only a short trail is seen following moving objects. TV feels responsive with low input lag however some temporary image retention is present after viewing static HUD elements in games.See our Video Games recommendations
Fairly good choice for HDR movies. Unfortunately native contrast ratio is low so blacks appear gray in a dark room, and local dimming is poor. Can produce bright, vivid highlights which is good and supports both the HDR10 and Dolby Vision format.See our HDR Movies recommendations
Good choice for HDR gaming. Supports both Dolby Vision and HDR10 and can produce bright, vivid highlights due to peak brightness and wide color gamut. Feels responsive due to low input lag and little motion blur which is good.See our HDR Gaming recommendations
Decent PC monitor. Sides of the screen remain accurate when viewed from up close. Feels responsive due to low input lag and little motion blur. Supports chroma subsampling for clear text no matter the content.See our PC Monitor recommendations
The stand is made of heavy stainless steel and has a handy space in which to hide a few cables, for a clean look.
Footprint of the 55" TV stand: 33.9" x 15.4"
Another LG TV with a fully white back cover. It shouldn't be seen in most cases, but it's nonetheless original and noteworthy. It might matter more in some rare room setups where the TV sits in the middle of a room.
The glass sits above the borders. This gives the LG UH8500 an interesting look when viewed from up close. The pixels of the screen don't start right at the edge of the borders, though - the edge and the pixels are separated by a black space.
This TV has an IPS panel, and so isn't able to produce deep blacks. Compared to other IPS TVs, it managed to do a little better than average.
We set local dimming to 'High' for this test, but we found that it darkened the dot too much. For most content, the 'Low' or 'Medium' value of 'LED Local Dimming' would appear more useful, in that it will not darken small highlights. Overall though, the dimming performance is really poor.
SDR peak brightness for the LG UH8500 is bad. The UH8500 can't get brighter than 300 cd/m², and the local dimming also dims too much the 2% window, which is a bit disappointing for this LED TV, since it is in the high end of LG LED TV lineup.
Update: Retested with a HDR signal and local dimming 'High'. It got a bit brighter, but it still isn't a very bright TV as far as HDR goes.
As most other LED TVs, gray uniformity is bad. At least, there is no obvious large banding issues so panning shots over playing fields shouldn't be much bothering.
As with other IPS TVs, the TV can maintain good contrast and color saturation when viewed from the sides. Picture still begins to deteriorate at more extreme angles.
The LG UH8500's black uniformity is decent, without any obvious clouding or light bleeding.
The picture above shows the TV fed with a 10 bit input signal. Our 10 bit gradient pattern isn't displayed perfectly, showing some minor color gradation issues, but it is still a lot smoother than when the TV is fed with an 8 bit signal. 10 bit HDR content should then be free from obvious banding.
Very good pre-calibration values. For most people, a professional calibration wouldn't make much noticeable difference.
We were able to obtain great results with relative ease, although it always takes more time with the 20 point values. It does get more precise, though.
The LG UH8500 offers the option to output a wider color gamut in all of its picture modes. It will be set to 'Wide' automatically when in the HDR picture mode. Unfortunately, even with the 'Wide' setting, the range of color doesn't increase much. TVs with higher DCI P3/Rec 2020 numbers are going to be better for HDR.
The UH8500 has good performance for DCI-P3, but at very high and very low luminosity colors lose their saturation.
The UH8500 TV have some image retention and it is a bit worse than what we have see on the UH9500. We can clearly make out the colored logos from the static image of the test video right after the 10 minutes exposure to the burn-in scene, but it was completely gone after 6 minutes of recovery.
A few lights won't be a problem. A small rainbow effect can be seen around bright reflections, though.
As long as the TV is being watched from directly in front, there is no crosstalk to be seen. As with other 3D TVs, slight vertical angles or wide horizontal angles will create crosstalk.
The pixels response time is quick, so there isn't a long trail following moving objects. There is a small amount of overshoot that isn't apparent.
Blu-ray movies play smoothly, as do movies played over cable or satellite. Streaming movies might show some judder if you do not enable motion interpolation (TruMotion).
Motion interpolation (TruMotion) has to be enabled to enjoy streaming movies without judder. The 'Smooth' pre-set will add the soap opera effect, but using a low custom value can remove judder without adding noticeable soap opera effect.
The 1080p input lag is low enough for any fast-paced game. The TV's lag even remains at playable levels outside game mode, allowing for more picture options to be enabled. Unfortunately, motion interpolation adds too much lag for games to be properly playable. Those looking for that option for gaming should look for a different TV.
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.
It supports most standard PC resolutions, except for 1080p @ 120Hz. To enable chroma 4:4:4 for sharper text, go in the input menu and change the icon of the input to 'PC'. For 4k resolutions, you must also enable 'HDMI ULTRA Deep Color,' which you can find in the 'General' menu.
Input lag in PC mode is the same as in game mode.

This TV was tested with "Magic Sound Tuning" enabled. Good low-end extension, especially for a TV. Very good maximum loudness too, however, the TV is likely to pump at higher volumes. The frequency response, after applying Magic Sound Tuning, improves noticeably and becomes flatter and more balanced.
Good distortion results overall; unremarkable performance.
Most of the popular apps are available, including YouTube, Netflix, Amazon Video, and a web browser. The overall number of available apps could be better, though.
Ads can be found in the LG content store, and you can only opt-out of personalized advertising.
Control buttons for basic functions can be found under the middle of the TV, right under the LG logo.

We tested the 55" (55UH8500) and expect, for the most part, our review to be valid for the other available sizes.
If someone comes across a different type of panel or if their LG UH8500 doesn't correspond to our review, let us know and we will update the review.
The LG UH8500 is a good choice for a wide living room with seatings on the side of the TV. Unfortunately, when watched from front or in the dark, there is a lot of better performing TVs.
