I believe that Sharp model has a DVI-I input. It should handle both -D and -A formats..

Find out what DVI format the computer video card is using. It may be DVI-A or DVI-D. After you get that info find the matching cable for it.
This guy has a lot of info on the format

If the video card only has a VGA output I think you can get adaptors to convert the signal to DVI.

Hope this helps!

Let us know how this works out for you.
