monitor ports and dual screen

I only appear to have one "monitor port", think this is called VGA at the back of my desktop PC. I have 2 monitors I'd like to use as dual screen. Does the 1 port hamper this, or can it still be acheived, if so how? PC is XP if that makes any odds.

You can use an adapter (splitter) to display the same contents on both screens, however if you wish to have the contents spanning 2 monitors then you need another graphics card.

Does a docking station on a laptop solve this issue. Afaik I only have 1 graphics card, I can view certain windows on the laptop, and others on the monitor attached to the back of my dock station.

Can you send a link to an adapter and rough idea on cost.

And is the monitor port typically known as VGA or something else.

The blue ports are VGA yes, and with a laptop it is still the one graphics card but you can use the laptops monitor as well as an external monitor to display the same desktop without need for an adaptor, you usually switch between monitors using the Fn (function) and F5 keys.

The docking station won't really help.

Various VGA adapters are here -

VGA port or HDMI port or DVI port

They all look different (google image search)  but are all used for monitors

With my docking station I can definately span wndows across both monitors, as opposed to just mirror whats on my laptop screen witht he monitor attached to the docking station. Perhaps I have a decent graphics card that supports dual monitors? How would I check if the graphics card supports dual or just mirrored monitors?

Clearly it does support dual or it wouldn't span....
I'm surprised, what model laptop do you use?

You should also be able to extend the internal and external monitors. I haven't seen any that don't support that, unless maybe if you don't have the correct graphic driver installed.

intel graphics and media control panel calls my setup an "extended desktop" which I assume is the same as spanning..

Yes you are running extended or dual monitors when using your docking station and an external monitor.

Yes you can plug two monitors directly into your docking station.

Yes you might need to get monitor with a DVI cable OR a VGA to DVI adapter (those are cheap).

assuming you want two EXTERNAL monitors vs. 1 laptop display and 1 external

here are some pictures
