Is there a device I can buy that will convert the analog signal to digital?

You may find that a USB-to-DVI video adapter costs less than either a new monitor or a full-on VGA-DVI converter.

ex: http://www.amazon.com/Diamond-BVU195-Display-Adapter-included/dp/B002GHBW4S/ref=sr_1_1?ie=UTF8&s=electronics&qid=1271951907&sr=8-1

This works best if you are using the laptop's external display primarily for office work, web browsing, or other non-intensive graphics applications. I would not recommend it for 3-D gaming or for watching movies.

Yes, there seem to be Adapters available.

That adapter will only work if the monitor accepts an analog signal over a DVI connector. Most don't. –  coneslayer Apr 22 '10 at 14:46
    
Yeah, I bought a similar $5 adapter and it did not work :( –  Corey Apr 22 '10 at 14:53

There are, but they are quite pricey. For example:

VGA to DVI Converter/Scaler

VGA / HDtv To Dvi-i Scaler / Converter

VGA to DVI Converter

A simple VGA<->DVI adapter will work the other way (DVI output to VGA display).

Thanks. I guess it'll just be cheaper to buy a second cheap monitor then! Makes me wonder why the hell Dell would put a VGA port on a new >$1000 laptop that has a discrete graphics card... –  Corey Apr 22 '10 at 14:54
    
No HDMI port either? –  coneslayer Apr 22 '10 at 15:33
    
DVI -> VGA assumes that the DVI port outputs a DVI-I or DVI-A signal. Many cards do, but there are a few that are DVI-D only and require active conversion. –  afrazier Apr 22 '10 at 15:39
