Is it posssible to connect two external monitors using a single HDMI port, perhaps using a special adapter/splitter?

The two displays are currently connected to a desktop using VGA and DVI.

If your DVI is DVI-D, it can run dual displays. But if your computer has both HDMI and DVI ports, this is a great way to get two separate monitors. – Chris K Mar 19 '13 at 20:22
    
All I have is a HDMI port on my laptop. I wanted to replace my desktop at work with this laptop and still use my dual screens. I guess this won't happen. – Dominic Goulet Mar 19 '13 at 20:32
    
Ah, you can look into getting a docking station, but yeah, laptop graphics cards aren't as awesome as most desktop ones. – Chris K Mar 19 '13 at 20:42

You should be able to with an HDMI splitter.

You can get an HDMI Splitter and your computer will output to that splitter.

Your computer won't know the 2nd monitor exists. So as a result, you won't be able to make dual monitors out of it. Instead the 2 monitors will be a mirror display of each other.

Which means that it is pretty useless ;-) Thanks for the info! – Dominic Goulet Mar 19 '13 at 20:15
    
Right, but the other way around could be helpful- if you have multiple PCs and a KVM switch. – Gaʀʀʏ Mar 19 '13 at 20:47

Yes, using an HDMI splitter, but it will only have one source (aka one display, not extended display).

Ok so the two monitors will actually display the exact same thing, without the ability to extend the desktop? – Dominic Goulet Mar 19 '13 at 19:26
    
Correct, all the device is doing it making two copies of the video for two wires, you will not be able to make the screen's show different things. – David Mar 19 '13 at 20:34
