High definition resolution for stunning image quality. LED backlight delivers sharper picture quality with crisp detail, vibrant true-to-life color, and superb contrast. More energy efficient than both plasma and basic LCD TVs, an LED TV is economical and helps the environment. The thin frame on Haier's LED HDTVs measures under an inch. This makes for more viewable screen on a TV with smaller overall dimensions, allowing a larger screen to fit in smaller spaces and making it easier to get lost in the high definition picture. The Energy Star label means a product meets strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of Energy. By choosing Energy Star® qualified electronics, you help prevent global warming and promote cleaner air without sacrificing the product quality and performance you expect. The Auto Volume Leveler lets you enjoy watching television without the annoying volume fluctuations between channels or when the program goes to commercials. Simply set the volume to your preferred listening level and the AVL automatically regulates the sound level. Mobile High Definition Link allows you to connect compatible devices, such as smartphones tablets, and the Roku Streaming Stick™ directly to the HDMI port on your HDTV.
