Our Verdict
Slightly above average for a range of usage. Movies in a dark room are slightly worse than average due to the low native contrast ratio. Motion handling is worse than most other TVs. The picture remains accurate when viewed at an angle.
- Image remains accurate when viewed at an angle
- Smart platform works well
- Poor motion handling
- Bad dark scene performance
- Screen has poor uniformity
Slightly below average for movies in a dark room. Native contrast ratio is low, and local dimming doesn't work well so blacks appear gray. Movies from a Blu-ray player are smooth.
Good for watching TV in a bright room. Screen is bright enough to combat moderate glare, and the reflection handling is slightly better than average. The picture remains accurate when viewed at an angle and the smart platform works well for casual viewing.
Good for watching sports. Image remains accurate when viewed at an angle. Motion blur is worse than average, so some trails can be seen. The gray uniformity is also worse than average, and some dirty screen effect is visible.
Good for gamers. Picture quality is slightly above average, but unfortunately the motion blur is a bit worse than most other TVs. The input lag for SDR content is very low which is good and feels responsive.
Average for HDR movies in a dark room. Native contrast ratio is low so blacks appear gray, and local dimming doesn't work well. Supports HDR10 but can't produce bright highlights and the color gamut is not very wide.
Poor for HDR gaming. Picture quality is slightly above average but blacks appear gray. In HDR mode the input lag is very high and can't be reduced. Motion blur is worse than average, so a trail can be seen following moving objects. Can't get very bright highlights and color gamut isn't very wide.
Slightly above average as PC monitor. Picture quality is a bit better than average, and colors remains accurate when viewed at an angle. Unfortunately the RGBW pixel structure results in some lines appearing fuzzy (see supported resolutions section of review). Supports chroma subsampling.

Popular TV Comparisons
The LG UH6550 has average picture quality, with a low contrast ratio so is better suited to a bright room. Unfortunately for the price you don't get a lot of value so it is hard to recommend. Keep this in mind when viewing our recommendations below.
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.
