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.
- Wide viewing angle
- Good for sports and video games
- Great WebOS 3.0 smart platform
- Sub-par picture quality in a dark room
- Peak brightness could be better
The LG UH8500 is a nice looking TV. Its recess glass, shiny metal stand and its completely white back are some of the details that makes it stand out. There is a high end feel to it.
Except for in some dark scenes, the LG UH8500 delivers good picture quality, with rich colors, for a wide variety of content. It is also HDR-ready and looks decent for this specific kind of content. It doesn't have any issues with judder. Lower-resolution content, like DVDs, also look good.
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.
The LG UH8500's black uniformity is decent, without any obvious clouding or light bleeding.
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.
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.
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 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.
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.
Sports look good on the LG UH8500. Action stays clear even on some of the fastest plays. So do players, balls, or cars, none of which will look blurry while moving at full speed. The color uniformity of the fields is not really good though, which is especially noticeable on panning shots.
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 LG UH8500 is a good pick for video games. Low input lag keeps everything snappy and responsive, and games with quick movement, like first person shooters, won't appear too blurry.
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.
- 20% 1080p @ 60Hz @ 4:4:4
- 20% 1080p @ 120Hz
- 20% 4k @ 30Hz @ 4:4:4
- 20% 4k @ 60Hz
- 20% 4k @ 60Hz @ 4:4:4
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.
The sound isn't impressive, but it's decent overall, for a TV. A soundbar would still be a better solution for even better sound, though.
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.
LG has improved its already good WebOS smart platform to version 3.0. The presentation looks great, navigation is quick, and the app selection covers the basics. In terms of usability, WebOS still has the edge when compared with the smart platforms offered by other brands.

Differences between Sizes and Variants
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.
Compared to other TVs
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.
The Samsung KS8000 is a more versatile TV that outdoes the picture quality of the UH8500 as long as it is watched from straight on. If you have seating at various positions on the side of the TV, then the UH8500 will maintain a better picture quality at an angle. As a whole, the picture quality of the Samsung KS8000 is more beneficial. Only get the UH8500 if you want 3D.
The 2016 Vizio P picture quality is better when viewed directly in front. Only when viewed from a pronounce angle the LG UH8500 gets the edge. The LG has the best smart platform experience and 3D but this is not enough to recommend it over the better Vizio P.
Both TVs offer a similar picture quality. The Sony x850d is better for sports. It can also get a little brighter which make it a better choice for HDR. The LG UH8500 have 3D and offers a better smart TV experience.
The LG UH7700 have a close picture quality but still offers a little less on all fronts. The UH8500 is better for movies (dark scenes) and maintains higher details in sports and video games. It is also the only one with 3D.
Conclusion CHECK PRICE
LG's UH8500 is the best of their LED TVs that we have reviewed so far. It doesn't offer the best picture quality when compared to LED TVs from other brands, but those looking for a TV that can maintain its picture quality from wider angles won't find better than this set, except for the more expensive OLED TVs. However, for late night movie watching, there are a lot of better options. In the end, the LG UH8500 is a good TV all around, and should please most who choose it.
Questions & Answers
Update 10/5/2016: We bought one. Review should be up within 2 weeks.
Update 10/7/2016: The review is up.
The luminance does also play a part, though. We do one test with luminance at 100 cd/m2, and another with maximum luminance.
Apart from contrast and viewing angle, both TVs have pretty similar, very good picture.
Yes, with a 4k 3D movies the LG UH8500 will display 1080p resolution for each eyes.
The UH8500 does support HDR10 (Xbox One S and PS4 Pro), but it has an input lag of around 60ms when in HDR mode, which is high and not really the best for gaming unfortunately. It also supports Dolby Vision, but there are no consoles which support it yet.
