Of course, the trick is getting 6 monitors that are all the same and display the same colours. We have a stack of Syncmasters here at work, and getting just 2 of them where you don't notice a colour change over a dual monitor setup, is pot luck.

 

No joke. I had mismatched monitors for years and years until I finally bought six of the same model all at once. Much better now.
