I recently overcame a debilitating condition. For a few years now, my master bedroom TV was only displaying in 720p while all the other TV's in my house displayed 1080i. This was greatly preying on my mind. Then the other day I happen to glance at the cable box and there in the front is an inconspicuous button labeled "format". I press it a few times and notice the TV cycle through 720, then 420, then with trembling hand, 1080i. HUZZAH! I was so excited I felt compelled to go downstairs and drag my wife up to see! She dutifully nodded her head and walked away but Im excited. No more watching that crappy 720p like a chump.
