You don't even need a wide-screen monitor for that. I like to turn my coding screen 90 degrees, to portrait mode, to get more vertical space and still can see the line at 120 characters.
I call it the TIE-fighter setup, the screen in the middle is in landscape mode and the two others are in portrait mode, gives a lot of screen-space without having to turn the head much to see it all
I also prefer the TIE-fighter setup, and didn't have a name for it until now. However, I find that 120 characters is too wide as soon as you want to do anything other than code on that screen.
Maybe Dumbo setup? The outer screens would be his ears. Not happy with the name, but best I could think of today. I'm a developer, so by definition bad at naming stuff. TIE-fighter setup is the lucky exception
