A revamped design based on last year's E-Series, Vizio's E55-D0 has ditched the moribund smart TV interface in favor of a new Google Chromecast-based approach. It's a more flexible smart TV design for providing streaming entertainment. The E55 is a member of Vizio's budget line, which means that it doesn't support 4K or HDR (high-dynamic-range) programming. However, a full-array LED backlight design with local dimming provides for a punchier picture and makes the $480 E55 a very attractive choice as a budget TV.
