As a 3D Artist I have my main screen with a 3D package on the left (usually Autodesk Maya or zBrush) and reference art on the right.
Also when not doing work I have browser on the left, and movies/games/porn/whatever on the right.
I have two 22" screens at home and work in a mirror setup. 99% of the time the LH screen is email & tickets via an RSS feed to the app bar in Outlook. RH screen is either dev tools I am working with or web browsing. Could not go back to one screen now.
Far quicker to look left & right rather than tabbing or lining up windows...
I don't mean to hijack the thread, but to save making my own, I have another TV in my room that isn't being used but it doesn't support 1080p like my monitor does. I've tried plugging it in before but it was a pain as it made everything go at 768p, but is there a way around this?
