Our Verdict
Good TV for a mixed usage. The LG UJ7700 has a wider viewing angle than average and decent picture quality. A combination of low motion blur, low input lag and excellent smart features makes it quite versatile.
- Decently bright
- Low input lag which is great for gaming
- Great smart features
- Picture quality in a dark room is below average
- Local dimming feature isn't great
Average choice for movies in a dark room. The UJ7700's blacks are not very deep or uniform. The local dimming feature is also better kept disabled since it can often be quite distracting.
Decent TV for watching TV shows. The viewing angle is a bit wider than average, and the WebOS smart platform is excellent. Unfortunately, though, it's not the brightest in SDR, which can cause issues in well-lit environments.
Good TV for watching sports. The LG UJ7700's picture is quite uniform and has little motion blur, but there is some dirty screen effect. It also has wider than average viewing angles, making it good for game days with a lot of company.
Great TV for playing video games. Input lag is incredibly low, and, motion is suitably good as well, making the whole experience quite responsive.
Good TV for HDR movies. Gets brighter than most other IPS LED TVs, and features Dolby Vision, which some users might appreciate. It can also display a wider range of colors without gradations, which is important for HDR.
The UJ7700's input lag does not deteriorate with an HDR input, which is great. The TV's already very good gaming capabilities translate well with HDR content.
Average PC monitor. Necessary resolutions are present, and the wider viewing angle helps keep the entire screen uniform when sitting close. It isn't the brightest though, and the RGBW pixel structure can cause some issues with straight vertical lines.

Popular TV Comparisons
The UJ7700 is a good TV, but it's in the most popular price bracket of the market, so it has a lot of competition that often offers better value.
The Samsung MU8000 is better than the LG UJ7700 unless you have a wide seating area. The MU8000 uses a VA panel, which has better native contrast and black uniformity for dark room viewing, and it's brighter with most content. The MU8000 also has a faster response time. The UJ7700 uses an IPS panel which is better suited for a wide seating area in a bright room. The UJ7700 uses a different sub-pixel structure which may bother some people in certain viewing situations.
The Samsung MU7000 and LG UJ7700 offer very similar overall performance. The UJ7700 uses an IPS panel which is better suited for a bright room with side seating or if you like to move around with the TV on. The MU7000 has a VA panel, which is better suited for a dark room, but has worse viewing angles so the image is best viewed from directly in front. The UJ7700 uses a less accurate sub-pixel structure which may bother some people for PC use.
The LG UJ7700 is better than the LG UJ6300. Unfortunately, the UJ6300 has issues with temporary image retention and static images can remain visible on the screen for a few minutes after they have been removed. The UJ7700 does not have this issue. The UJ7700 also has an extra HDMI port compared to the UJ6300. Both TVs use a slightly less accurate sub-pixel structure which may bother some people for PC use.
The Samsung MU6100 and LG UJ7700 are very similar, but due to the difference in panel types, one may be better than the other depending on your needs. The UJ7700 uses an IPS panel which is better suited for a brighter room with a wide viewing angle. The MU6100 uses a VA panel which has better contrast and black uniformity, making it better suited for a dark room. The UJ7700 uses a different sub-pixel structure which may bother some people for PC use.
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.
