First I'm jealous of all you hotshots running dualies out there and me stuck with my silly old 1/2 ton....jeez just think of the runs I could make to the dump with a nice dualie setup

If'n by chance a second monitor should happen to fall from the back of a passing Fedex truck (we have ways of making stuff fall out the backs of trucks here....have you ever had to play 52-pickup with a bag o'trash that bounced out the back of yer pickup on the way to the dump >

), but I digress....If'n you already own an ATi video card with the dualie setup (video and tv) how you go about fixin her up to run dual monitors? What control do you have over screen resolution when your running different size monitors?
....headless machines....what's that? Is that like when you get on down to the bar and get all liquored up and you pick up an ole emachine running a celeron with no monitor and you wake up in the morning wondering what the hell is that sitting on my desk. So you go and cover it with a blanket and go back to bed hoping that she'll be gone when you wake up later in the morning...but I digress....does it mean running more than one machine of a single monitor/mouse/keyboard? If so how's that set up and what the oldest OS you can be running on a headless machine?
Thanks All
