I read somewhere that you only need an active adapter (usb powered) if you want resolutions greater than 1920x1200.

I also heard from someone that you need it when running triple-monitor because more than two displays drains too much power.

So to connect a 3rd monitor @ 1920x1200 to my video card's DisplayPort Port, do I need to spend the extra $100 and buy the active adapter?
