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
The H6400 has inherited the 2013 F6400's top-notch image quality. It's not quite a five-star model, but it's good enough to make two appearances in our 40"to 48" TV buyer's guide.
Good Value 3D TV
The LA620V delivers good, accurate picture quality. Contrast, however, is low (750:1), making the black look more like grey. This TV is therefore restricted to three out of five stars. Otherwise, viewing angles are wider than average and there's a good range of extra functions.
Sony's R473 budget TV offers great picture quality with high contrast, faithful colours and near-perfect responsiveness at a low price, but in terms of extra features it's no man's land. Choice is yours.
