If it ain't broke, don't fix it. The H6400 has inherited the 2013 F6400's top-notch image quality. The onscreen picture is natural and accurate, and image processing works well. Another real boon here is the excellent contrast, which beats some top-of-the-range models. Although it just missed out on five stars, it's probably one of the best value-for-money TVs currently available.
Best of the rest
Samsung UE40H6200 (UN40H6203)
The H6200 is very similar to its big brother, the H6400, except that Samsung had the VA panel made by AU Optronics rather than do it in-house, which is a good thing because it gave it higher contrast (5240:1). It also has nice motion compensation and 3D, as well as Samsung's usual connected services. On the downside, there's no touchpad/gyroscope remote.
Reasonably-Priced 2D TV
Sony KDL-42W705B (KDL-42W705)
Not only does the Sony W705B television benefit from the excellent finish of the W805B, it also inherits its impressive colour fidelity and a contrast that puts top-of-the-range models to shame. However, the W705B loses points for its lack of 3D compatibility and motion compensation, which anyone used to a smoother picture will miss.
The H5500 series provides good contrast and faithful colours. Unfortunately, like many LCD TVs, it has narrow viewing angles. To get the best picture quality, try sitting straight in front of the screen. This model doesn't do 3D, but you do get a widely compatible media player and Samsung's connected services, such as S-Recommendation.
