The world's largest HDTV is 200 feet wide and 80 feet tall. The 16,000-square-foot screen is made up of 158 panels, weighing 165,000 pounds. It's lit up by 9 million LED lamps. But it's only 720p.
Located at North Carolina's Charlotte Motor Speedway, this most gargantuan of boob tubes dwarfs the Dallas Cowboys' former giantest HDTV by around 40 feet. (Consider: A standard tennis court is 78 feet long and 36 feet wide. This TV fits 5.5 tennis courts, side-by-side.) On the other hand, the Cowboys' TV is still 1080p. (Quick! Someone calculate the Lechner distance for a 720p TV this big vs. a 1080p set.)
