In Windows XP (or 2000, or probably Vista) you can just right-click your desktop background and hit “Properties”, then “Settings”.
You’ll see screen “2” (or 3, 4, etc) grayed out. If you click it and check the box marked “Extend my Windows desktop onto this monitor”, it’ll become active.
You can drag the monitor where it is in relation to your primary one so your mouse moves smoothly from one to the other, and drag the screen resolution slider until it looks right.
99% of the time that’s all you need to do.
That’s good to know. Thanks.
If you know: You mean, in XP Pro if I just throw a leftover video card into my PC (which has integrated eg; on-motherboard video) and hose up another monitor (and check the “2 monitor” desktop option as you said) BOTH video outputs will work; and the add-on card won’t “override” the integrated video?
Joyful if true! Now I have a Saturday experiment!
