When it comes to HDTV and 3DTV I never saw a display that could quite take my breath away until this weekend. I am new to the Philadelphia area and I heard about this HUGE HDTV and 3DTV in the Comcast Building, a skyscraper in Center City, Philadelphia, Pennsylvania. The 25.4 feet tall, 83.3 feet wide, 2,000 square feet high-definition LED Screen situated on a wall in the winter garden is an amazing piece of art. I was told that I had to go see the HDTV and 3DTV when I first moved here in May, and I’ve been trying to make some time ever since. This weekend was pretty laid back and turned out to be the perfect opportunity.
