The Vizio E550VA is a mid-range to high-end 55" LCD 1080p HDTV similar to the Vizio E420VO. Unlike the E420VO, the E550VA does not feature a 100,000:1 contrast ratio, instead sporting only 50,000:1. However, the E550VA does boast a 120Hz refresh rate and direct USB photo viewing. Otherwise, the E550VA sports the same basic features as the E420VO, such as being Energy Star 4.0 compliant and an ambient light sensor.
The E550VA's 120Hz provides a much clearer picture, especially during fast actions scenes, as the image displayed on screen refreshes 120 times per second: twice as fast as standard television sets. Its USB photo viewing feature allows for direct display of most popular image file formats via USB flash drives/USB hard drives. Additionally, the E550VA's inbuilt ambient light sensor detects light levels in the room and adjusts its screen brightness accordingly, reducing energy consumption and providing a consistently clear image.
