I'm really ashamed of myself for procrastinating on the issue of dual monitors. Today, for some odd reason, I decided to try a little experiment and connect up an old 21-inch monitor next to my newer, higher rez 24-inch monitor. I had the old monitor, had the card that supported two monitors, even had the cable to hook it up. Kept holding off saying "no, I'm going to wait until I can scrounge up $250 to buy a good matching monitor."
Dumb de dumb dumb.
What I got for free with the older monitor is a dramatically better workflow experience. I have moved the multidock / console to the slightly smaller monitor and left the track view and pro channel in the main monitor. Wow. Just Wow. The difference is NOT subtle.
Working in X2 with a single monitor is like playing the guitar with one hand behind your back.
