Ya, 1 Monitor will have to be DVI or HDMI and the other has to be VGA.
that USB adapter will work as well, but I would try to invest in a better monitor.
But, buying that adapter will give you the option of running 3 screens down the road if you buy a DVI/HDMI monitor.
Be carefull, just because there are three connectors doesn't mean it will support three monitors. The video card has to have the circuitry to support it. You may be able to connect three monitors to that motherboard but end up with each monitor showing the same screen (mirrored) with no way to change it. I've seen lots of (low end) video cards with VGA and DVI that didn't support dual monitors.
PainfulGlory, read the manual for that PC and see what it says as far as video support. If no paper manual came with it have a look for a PDF version on the CD that should have come with it.
I never said 3 monitors, just 2. And we know it has the circuitry for a Digital and Analog display built in, since there is a DVI-D, HDMI (these most likely share the circuit so you can only use one or the other), and the VGA.
I just looked up motherboard and it also has only a DVI-D connector, as well as a VGA, HDMI and Display Port.

Some of use are smarter than others on this stuff, but we weren't born that way. I've learned a lot by trial and error. All you can do is try to save the next guy some of the error.
