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.


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...

  • No HDMI port either?

  • 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.

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.

  • Yeah, I bought a similar $5 adapter and it did not work :(
