Here's a big, beautiful LED TV from Sony. The KDL-46EX700 has, in our opinion, the ideal specs to get you the most bang for your buck, including 120 Hz refresh rate and an LED backlight. LED TVs are brighter and more energy efficient than conventional LCDs. This model is particularly green, featuring energy-saving features like a presence sensor and a power-cutoff switch. Great for a fairly large living room.
