I have dual monitors at work, and I love 'em! At home on the other hand, I am still dinking around with just the single monitor. It isn't that I am too cheap to buy a second monitor, it is just that I don't have the desk space.
Anyway my dual video card is made with one VGA port and one DVI port. The setup works really well, except the color is just slightly off between the two monitors.
No problem though, because I have just learned of a tool that will calibrate the colors to make them the same on both monitors. This is good news for your graphic artists out there not using Macs. This tool is called Calibrize.
From their site:
Calibrize is free software that helps you to calibrate the colors of your monitor in three simple steps. Just download the software and follow the procedure to generate a reliable color 'profile' and adjust the colors of your monitor automatically.
Of course, like most of the tools I mention, it is absolutely free! Just download it, and follow the prompts. Fairly simple.
Do you use multiple monitors? How many do you use? Does it make you more productive? Sound off in the comments!
