Setup:
- Laptop: Macbook 13" Retina Pro model ME865LL/A
- Laptop screen running at native 2560x1600 resolution
- 1st Thunderbolt output connected to a Matrox Triple Head 2 Go DP Edition and pushes two Lenovo ThinkVision 22" widescreen monitors that appears to the laptop as a single 3840x1200 display
- 2nd Thunderbolt output connected to an HP S2331 widescreen via TB to DVI cable running at native resolution of 1920x1080
I've since re-arranged my desk/mounts and have two rows of displays instead of three, it's been working out great
