Our Verdict
The LG 75UK6570 is a good TV for most uses. It is well suited for gaming in SDR or watching TV shows and sports during the day. Unfortunately, dark room performance might be disappointing to some people, and although it supports HDR, there is little benefit to it as it lacks a wide color gamut and isn't very bright in HDR. The wide viewing angles, low input lag, and chroma 4:4:4 support make it a great choice for a computer monitor.
- Image remains accurate when viewed at an angle
- Excellent low input lag
- Disappointing dark room performance
- HDR performance is lacking
The LG UK6570PUB is a mediocre TV for watching movies in a dark room. It has a decent contrast ratio, but inadequate black uniformity, so blacks appear gray in a dark room. It also lacks a local dimming feature. It is able to remove judder from true 24p sources like a Blu-ray player, but not when they are being played from a cable box that embeds the movie in a 60p signal.
This is a very good TV for watching TV Shows during the day. It has good peak brightness in SDR and excellent reflection handling, and the wide viewing angles make it great for watching TV while doing chores around the house. Older sub-1080p content is displayed well, as the UK6570 doesn't use an RGBW sub-pixel arrangement.
Good TV for watching sports. It has a fast response time, but there is a short blur trail behind fast moving objects. It also has mediocre gray uniformity, and there is noticeable DSE that may bother some people. It is bright enough in SDR for most rooms, and has excellent reflection handling. It also has wide viewing angles, great for watching a game with a group of friends.
This TV is great for playing video games. It has the lowest input lag we've measured on a TV, great for even the most competitive gamers. It has a fast response time, so motion is clear with only a short blur-trail, but the 120 Hz PWM flicker may bother some people and causes duplications. It supports most common input resolutions, but it doesn't support 1440p or 120 Hz.
The TV is only mediocre for watching movies in HDR. Unfortunately, it can't get very bright in HDR and doesn't have a wide color gamut. It also has only decent contrast and disappointing black uniformity, so dark room performance is disappointing. It also lacks a local dimming feature.
This TV is good for HDR gaming. It has outstanding low input lag, with a fast response time, so motion looks clear and games are responsive. Unfortunately, HDR doesn't add much, as it doesn't have a wide color gamut and isn't very bright in HDR. It also doesn't perform very well in a dark room, as it has only decent contrast, disappointing black uniformity, and lacks a local dimming feature.
The UK6570 is a very good TV for use as a PC monitor. It has outstanding low input lag, ensuring a responsive experience. Chroma 4:4:4 is displayed perfectly, so text looks clear, and it has wide viewing angles, so the sides of the screen remain accurate when sitting fairly close to the TV. It also has a fast response time, so motion looks clear, and there is no risk of temporary image retention or permanent burn-in.

Differences Between Sizes And Variants
We tested the 75" UK6570 (75UK6570PUB) and for the most part, we expect our review to be valid for the 86" UK6570 (86UK6570PUB).
The 70" variant (70UK6570PUB) has a VA panel, and we expect it to have a better native contrast ratio, but worse viewing angles.
If someone comes across a different type of panel or if their LG UK6570 doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Popular TV Comparisons
The 75UK6570 is a good TV for most uses. It is aggressively priced, and beats most of the competition in the same price range. See our recommendations for the best 75 inch TVs.
The LG UK6570 is a bit better than the Samsung NU6900 unless dark room performance is important. The UK6570 has wider viewing angles than the NU6900 and better reflection handling, making it a better choice for bright rooms with lots of side seating. The UK6570 has a faster response time, so motion looks clearer with less blur trail. The NU6900 has a VA panel and is better suited for a dark room with no side seating.
Overall, the Vizio E Series 2018 and LG UK6570 are very similar. The Vizio E Series 2018 has a VA panel and is better suited for dark room viewing sitting directly in front. The LG UK6570 has an IPS panel and is better suited for a bright room with side seating. The UK6570 has an optional motion interpolation feature, great for fans of the soap opera effect. The LG also has lower input lag, great for gaming or use as a PC monitor.
The Sony X850F and the LG UK6570 are very similar overall. The X850F is brighter in SDR and HDR and has a wide color gamut. The X850F has better overall motion handling, with slightly faster response time, nearly flicker-free backlight, and better motion interpolation thanks to the 120 Hz panel. The LG UK6570 has much lower input lag, great for gaming or use as a PC monitor. The 85" X850F uses a VA panel, compared to the 86" UK6570 that has an IPS panel, so the XBR85X850F likely will perform better in a dark room.
These are two different types of TVs, so if you have a room with wide seating arrangement, then the LG UK6570 might be better due to the wide viewing angles. On the other hand, in a darker room, the blacks of the Samsung NU7100 are deeper and enhance the picture quality provided you sit straight in front. In terms of less critical differences, the LG UK6570 can handle reflections better and has a crisper image due to the faster response time.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
