The 1902 does not work fine. The design was defective, and when the monitor warms up, every minute or so it'll make a snapping noise and shut off for a couple...
This hooks up to a TV, right? I wish I had one of those! I never saw those in stores. I met the marketer of those down in the basement at E3 a couple of...
