Hi Amias,
I wasn?t talking about the card slot ? the Matrox device I was talking about plugs into your video port (HDMI or otherwise), and fools the VGA card into believing it?s a widescreen monitor, when in fact it?s a pair of outputs.
I?ll see if I can find a link for you?

Hello john,
No it doesn't have port replication or a card slot , just hdmi 1.4 and usb 3 , I think the I tel chipset does that Intel wireless video thing but I've never seen anything to receive it. I'd prefer to have a single connection if possible.
The Dell inspiron 7737 runs ubuntu 14.04 really well and I'd recommend it for linux use.
Cheers
Amias

In my, limited, experience you'll probably have problems running two
monitors at full resolution and refresh rate over a single USB connection.
There just isn't enough bandwidth. My tests were pre-USB3, however, so if
you can get USB3 then YMMV. Anyway, the detailed specs for the USB docking
station should state what resolution and refresh rates the video output can
drive so make sure you check that. Also, because you've already got one HDMI
port on your laptop, in theory you only need to drive one monitor from USB.
That should be possible. Linux drivers could also be an issue. I would
recommend buying a device from a reputable source that allows returns if it
doesn't work.
I've never come across a dual-HDMI cable. It sounds dodgy.
Shane.

I've seen people have very good luck with Matrox devices which emulate one
VERY wide screen, and in fact split that into two outputs. Think the one I

similar for 16x9 duals (32x9)...
They plug into your display output and tell the computer they're one display
device, but then separate it, so you just need to make sure whatever you're
displaying will then work with a single (or half) a screen.
Does the Inspiron not work with a standard Dell port replicator? Those have
twin display outputs usually...

OK,
So unless you get a HDMI to VGA adaptor, the dual head unit I?m thinking of isn?t going to work (it won?t take an HDMI input). However, you?d be okay with the TripleHead2Go device as that?ll allow a drive from DVI (and DVI to HDMI cables/adaptors are fairly common)?
http://www.matrox.com/graphics/de/products/gxm/
There?s where you?ll find all the info about the different models (It?s linking to the German site, don?t ask why, but when I browsed it, it was in English anyway)?
Cheers,
John
