Printed menus are almost always done in portrait orientation. If I were doing menu signage, the first thing I'd look for is a TV that can present information that way. Every time I see this, both in a restaurant and at a local distributor, and heck, at the airport, I'm impressed that it's not just a TV. It seems to be a totally different and exotic product simply because it's taller than wide and it adds a bit of cool to the environment.

No, I don't do signage. I'm just saying to think about this before buying anything.
