HDTVs usually come with different feature sets for different screen sizes. A set you can fit on your desk might only have a few HDMI inputs and little additional connectivity or features. A screen you can barely fit in your garage could come with Wi-Fi, 3D, and tons of options. Generally, these days, HDTVs larger than 40 inches typically come with Ethernet or Wi-Fi for accessing streaming media services like Netflix. This makes the JVC JLC47BC3000 a big surprise for a 47-inch LCD HDTV: For $949.99 (list), you do get a 120Hz refresh rate, a light sensor that can adjust brightness, and a USB port for sideloading movies, music, and pictures for playback, but no Web connectivity. In contrast, the less-expensive 42-inch Insignia NS-42E859A11 ($699.99, 3 stars) features integrated Wi-Fi to access Netflix, Pandora, YouTube, and even Chumby apps.
