The Vizio E420VO is a mid-range to high-end 42" LCD 1080p HDTV very similar to the Vizio E371VA. Unlike the E371VA, the E420VO does not feature a 120Hz refresh rate or the ability to view photos over USB. However, the E420VO features a superior 100,000:1 dynamic contrast ratio and a larger screen size. Otherwise, the E420VO and E371VA sport the same basic features, including an ambient light sensor and SRS TruVolume technology.

The E420VO's 100,000:1 dynamic contrast ratio provides it with a superior overall picture, allowing for deeper blacks and brighter whites. Its inbuilt ambient sensor detects in-room lighting conditions and adjusts the E420VO's accordingly, ensuring a more consistent picture quality and reducing energy consumption. Additionally, the E420VO's SRS TruVolume automatically evens out audio levels across commercials and programs for a more consistent volume that doesn't require frequent manual adjustment.
