Our Verdict
The LG UK7700 is a very good TV for mixed usage as it can handle reflections well, making it suitable for bright rooms even though the TV does not get too bright. Motion handling is decent and the TV can perform very well with video games and as a PC monitor due to its excellent low input lag.
- Feels very responsive due to excellent input lag
- Image remains accurate at an angle
- Blacks are gray and blotchy in a dark room
- Mediocre HDR support
This LG UK7700 has a mediocre performance when watching movies. In dark environments, the not so good contrast ratio does not make blacks look deep and the local dimming cannot help. The TV can display Blu-ray at 1080p and native 4k content well but its black uniformity might be an issue for some movie enthusiasts.
The performance of the LG UK7700 when watching TV shows is great. It has excellent reflection handling, decent SDR Peak Brightness, and ok viewing angles. When upscaling from the cable 720p input the UK7700 does a good job and the motion interpolation option can add some soap opera effect for those who like it.
The LG UK7700 is very good for watching sports. The good reflection handling and very good response time, along with decent SDR Peak Brightness, make it suitable for a relatively bright room and fast action content. The viewing angles are ok for a wide room and some sports fan might notice a little dirty screen effect on panning shots.
The LG 65UK7700 is very good for video game playing. It has an outstanding low input lag and great response time that will keep most gamers happy. It can accept most common input signals and its motion handling is decent. Make sure you enable the Game picture mode to enjoy the low input lag.
Watching HDR movies on this TV is mediocre. This is mainly due to sub-par contrast and the bad local dimming, which do not allow the TV to display deep blacks in dark environments. Although the 4k content is displayed well the HDR brightness is not enough to reveal the content as intended by the content creator.
This TV is good for playing HDR games It has very low input lag at 4k @ 60Hz + HDR, and because of its fast response time it a great choice for those who want to use it to play HDR games, although the not so good contrast will make blacks appear a little washed out and the colors will not be so vivid.
This a great TV for use as a PC monitor. The very low input lag and the good response time will make the PC usage experience a good one. Also if you wish to use this TV as a PC monitor you do not have to worry about the permanent burn-in risk or temporary image retention.

Popular TV Comparisons
The LG UK7700 is a TV that is ok for most usages without standing out for a specific characteristic. See our recommendations for the best 4k TVs and the best TVs.
The two TVs have different panel types. The LG UK7700 has better viewing angles, better reflection handling and is more appropriate for watching sports or TV shows in a room with many light sources and wide seating arrangement. The Vizio E Series 2018, on the other hand, is a better choice for a dark room where you will be sitting right in front. It has better contrast ratio, better black uniformity, and will provide a better movie experience in a dark room and better HDR performance.
The LG UK7700 is a better TV than the Samsung NU7100. The LG has better reflection handling, better response time, and wider viewing angles due to its IPS panel, so watching sports and TV shows on the LG is a very good experience. On the other hand, the Samsung NU7100 will offer a better experience in HDR movies due to the much better contrast ratio that can produce deep blacks in a dark room.
If you have a room with a wide seating arrangement, then the LG UK7700 is a better choice as the image remains accurate when viewed at an angle. If, however, you sit straight in front of the TV and watch movies in a dark room, then the Samsung NU8000 is a much better choice as it has a higher contrast ratio and can display deep uniform blacks, enhancing the picture quality. The Samsung NU8000 can get brighter to fight bright room glare and supports FreeSync for tear-free gaming sessions. The LG UK7700 has better reflection handling and a lower input lag, which is great for playing video games.
The LG SK8000 and the LG UK7700 have very similar performance. The LG SK8000 can remove 24p judder from movies better than the UK7700 can and can interpolate motion to higher fps than the UK7000. Also, the black frame insertion feature of the SK800 works better than the UK7700 and can make the image crisper. The LG UK7700, on the other hand, has lower input lag both in SDR and HDR and is great for gaming.
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.
