Our Verdict
The JU6400 is a mixed bag. It is an excellent option for gaming, great for sports and well-suited for a well-lit family room. Unfortunately, it won't be as good for movie lovers who like to watch TV in a dim room, as the TV has poor blacks and suffers from judder. Depending on your viewing habits it can be great, or bad.
- Great viewing angle.
- Very low input lag.
- Excellent motion.
- Poor blacks and contrast.
- Judder is present while watching movies even in 24p.

Differences Between Sizes And Variants
The 55" Samsung UN55JU6400 that we reviewed has a PLS panel (version FD05), which is a sub-category of the IPS family, and which produces grayish blacks, and has a wide viewing angle. If someone comes across a different type of panel used, let us know and we will update our review. Thank you in advance.
Some of our visitors reported that the 40", 43" and 48" version of the JU6400 has VA panels with better contrast ratios and worse viewing angles.
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.
