Unfortunately, the game doesn't work so well on a widescreen TV. When you take a 4:3 image and chop it into two screens, horizontally, you get two widescreen-ratio screens, which works pretty well. But with a 16:9 image, you get two screens that are super widescreen, having plenty of horizontal peripheral vision but not enough vertical vision. The game has a vertical split-screen option, but the problem is still there -- just in reverse form. It makes a game like Left 4 Dead, which is dark and chaotic, hard to play.
This isn't a problem exclusive to Left 4 Dead, though."
