Query: Seeing pink?

I have a multi-monitor setup from three different manufacturers (Samsung, Acer, Viewsonic). Like many other reviewers, my first attempt resulted in a slightly pink cast on one of my monitors (Samgsung SyncMaster 931c). But, I've managed to correct the problem with a little patience and slight pressure to the tip of the device. Take a few extra minutes and adjust the brightness and contrast and get it just right. Then, while it processes color, lightly press on the device where it says "Huey Pro". It'll create a better seal for sensors and you'll get dramatically better results.
