Windows 7 Setup dual monitor

[Enforcerke]

Hello, I read here: http://www.wikihow.com/Set-Up-Dual-Monitors
that you need 2 identical ports. But i have this on the back of my pc:

Am I able to use this for dual monitoring then? Because they are all 3 different.

If not, can I also buy something so it splits in two or something?

Thanks

It doesn't have to be identical. It's just a suggestion. You photo attachment is "broken" at my end. But basically, most PC can run at least 2 monitors at the same time.

BadRobot is correct. You should be able to use the VGA (blue) for one monitor and the DVI (normally white) for a second monitor. You shouldn't notice any differences between the two even though VGA is considered an analog connection and DVI is considered a digital connection.
