I like 3 monitors- but why should they all be the same?
It’s just like multi-core cpus: right now the manufacturers are building cpus with identical cores, because it’s easier and we’re still getting used to the idea. But it looks like the best performance can be had from building a cpu with several different cores, each optimized for different tasks.
I propose a 3 monitor setup like this:
Monitor 1, in the center, is a 22 inch widescreen set at 1680x1050 or higher, for general purpose work.
Monitor 2, to one side, a another 22 inch widescreen, but it’s oriented 90 degrees the other directly. This monitor is optimized for reading long documents.
Monitor 3, to the other side, is a small old 15 inch piece of junk. Use this monitor for laying out GUIs. That way, you’ll end up with something that still looks good on older systems.
