extending my screen

[ArtierSquare]

Hi all,
New here... first post and so forth.

I've been searching the internet for ages and had no joy finding what I would have thought was a simple thing.

On my desktop I have a twin out dvi card to run two monitors.

I should like now to be able to do the same thing for a laptop, presumably from a stand alone HDMI or DVI box of some description.

I can find plenty of splitters but no desk top extenders.

Does anyone know please if such a device exists...?

Laptops can output extended image to just one additional screen.
Splitters simply duplicate the input signal onto whatever amount of outputs it has. The signal (image) remains the same, eg clone mode.
You may have more luck using a USB displays but I'm not sure if that is possible to have 3 independent images with internal/external and USB monitors.

Thanks,
I was looking at the MacBook Pro which seems to do something similar to what I'm after. You can't of course use the laptop screen at the same time though, but I can live with that.
At the moment I have two redundant Eizos...

Something similar to this... ics-tech.kiev.ua/1450

It's not clear as it's russian, if this is exactly what I'm after. What I can't understand is why you can only do this from a desktop and not adapt a laptop to produce the results... surely if you can extend to one screen you should in theory be able to extend to many...

Laptop's screen already utilizes one output off the graphic card. 2nd output is used to allow external screen connectivity. So with standard laptops and I think Macs fall into this category using splitter will simply allow you to show the same screen over each monitor connected to the splitter.
If you need to have several external screens with different images or use them as video wall you might be looking at something like this: DualHead2Go. Such device will be much more expensive then splitter.

Thanks once again,
It seems that with Matrox you can run all three screens independently or as extended screens so certainly the type of thing I'm after.

I can't post links until I have 5 posts on here but if I find anything else I'll come back. In the mean time if anyone should find the same thing for PC laptops do please let me know.

Regards

Thanks for the help... I have decided to go the route of Mac mini which uses HDMI and Thunderbolt as options to run two screens
