Setting up 2nd Monitor?

Ok so I have read the wiki and am pretty much ready to get my team going (my experiment on my friends account with my own seems to have paid off) and I am going to RAF 4 accounts this weekend.

Anyways my question is I have a new 22 inch monitor which is fine and I setup maximizer to show my main window on the left and then the 4 others along the right side. Now I have no problem doing this I really cannot see what the hell is going on in them half the time.

I have my old 17 inch monitor just kind of sitting here but I am not exactly sure how to set it up much less plug it in.

I am running Vista 64 and I have a ATI Radeon 4870 in my machine that is connected to my current monitor using DVI-VGA Adapter ATM (Although I think I should use the HDMI Adapter instead).

Can anyone fill me in on this one cause I really would rather have my 4 other slave screens split evenly on my 17 inch screen

Well, for my nvidia card I just plugged it in alongside my 22" WS monitor and then went to nvidia control panel, went to configure dual monitors, and then went to town.
