I recently setup a 4th display since it was just laying around and added it to my tri-display setup. 23" 1080p, 37" 1080p, 23" 1080p, and added a little 22" to the mix. This is my gaming/HTPC/workstation. I just do everything here. It's my little `pod' so to speak in the den.
Between the first three displays, (23", 37", 23") it's nearly 7 feet across. With my 22" added, it's nearly 9 foot across. It fills my view, even though the image makes it all look so tiny next to the TV that makes the monitors look smaller. I really like seeing tons of stuff though. No alt-tabbing for me.
Display 1: Media Center showing whatever channel (usually news/sports/weather) that I'm yanking over the air in HD from my antenna--I don't pay for service, I just watch the free HD stuff out there, there's plenty. This serves as one of my monitors when I tri-display game otherwise.
Display 2: My primary, the 37" 1080p. Whatever I'm actively working on goes there. Be it a movie, website, working in photoshop or playing a game that only works on a single display (old school games). It serves as the center display when I tri-display game.
Display 3: I have a USB cam feeding into a monitor here, I like to see what's going on outside, the weather, who's at my front door, etc. It takes an image when movement happens. Fun to see who came by day to day. Beneath is Foobar2000. To the right, Facebook. This monitor serves as my 3rd display when I go tri-display gaming.
Display 4: I keep my uTorrent downloads, Firefox downloads, my personal Forum website and my Gmail active on this display for constant monitoring.
All from a single computer, using Windows 7 x64.
After some good cable management, I'll make better photos. Just threw all this together for active duty between my busy schedule.
