I have a re-manufactured HP Compaq dc7700p Small Form Factor running Windows XP (for some reason inside the Windows Vista Boot Manager, instead of the WinXP NTLDR).

On the back of my PC, I have what looks like a DVI Port, and that's what I thought it was. When I bought a DVI to VGA Cable (to connect a second screen), it wouldn't fit. I took a look and found that the DVI connector was different to the port on my PC. I would love to post some pictures, but being a new user, I can't.

enter image description here What I want to know is what port this actually is, so that I can find a suitable converter.

The only difference between this and DVI is at the end with the 4 square pins and the +-shaped pin. The + pin is still there, but instead of the 4 dots, I have two flat lines underneath the squares (above the +), which are of the length of 2 of the squares.

Looks like DVI-D to me too. Maybe this cable is what you're looking for.

It seems that your PC has a DVI output. Please notice that the DVI standard has different plugs, depending on the type of data that is sent through the cable (it could be both digital or analog). Refer to Wikipedia to see which port your PC has.

It's likely DVI-I vs DVI-D.

Take a look at this super user question that shows both (granted, a different question with similar answers).

Yours sounds like DVI-D single link.

Just so you know, a DVI to VGA cable will not work without the two pins above and two pins below the "bar" or "plus"; that is what carries the analog signal

Looks like it's DVI-I as was suggested by others. Check out http://www.playtool.com/pages/dvicompat/dvi.html
