The $400 40-inch model of the Vizio E400 line is recommended by The Wirecutter as the best television of that size for the money, as of February 2015. The review admits that smaller-sized televisions generally do not have the highest picture quality but lauds the Vizio E400 line as the best-looking television for the price.
The Vizio E400 has rich black colors, a noted rarity for televisions in the price range. LCD televisions have differing motion resolution, or their ability to accurately render moving objects without blurriness or odd artifacts, and the Wirecutter notes the E400's average (but not poor) motion resolution. One gripe the reviewers have with the E400 is the model's poor off-axis viewing, which refers to the ability to see the picture clearly from an angle. Users may experience difficulty watching the television if seated at an odd angle in their viewing room.
Amazon.com reviews of the Vizio E400 40-inch television note the television's crisp picture quality, light weight, slim profile, and ability to stream Netflix, Amazon Prime video and other content through the television. The reviews tend to remark on the television's odd interface, but note it is a problem a user can work around with third-party hardware and software combinations.
