My Thinkpad will do only 2 of the three available (I think the HDMI and DVI are the same output with a different plug)
Didn't know that. Thanks.

np There are usb video cards which should allow you a third display if you want to try it - also there was the Matrox DualHead2Go which made the output really big to the external monitor, then split it across two monitors. Not sure if that is still available though

There you go. I knew I was overlooking something and couldn't get over the brain freeze. I've more to consider now. Danke.

If I use a DVI Splitter, will the displays be cloned or will the Graphics card detect that two separate monitors are connected and drive independent displays? I have 3 monitors to connect and 1 DVI, 1 VGA and 1 HDMI port in the docking station. I could also buy an HDMI to DVI/VGA to drive the third monitor. Any suggestions/gotchas? And thanks to John for letting us know about monoprice.com. Thanks.

It will definatly just clone, doesn't matter if its dvi or hdmi or anything else. On nVidia cards and early ATI ones, DVI=HDMI internally, so you only have 2 outputs. As you've got a docking station you can't change to one of the later ATI cards, your only option is a usb graphics card. These are quite cheap £40 for a basic vga one, Matrox do some more advanced ones, but you should be able to add as many as you have usb ports.

The DVI splitter err.... splits the same signal to two displays. The HDMI output can drvie a separate DVI display.

We use DVI and DisplayPort at work (HP computers) for dual-monitor setups. I'm not impressed with HDMI hookups on monitors. It doesn't seem to be able to correctly negotiate the monitor's resolution (and II have two examples of this problem at my house). I supposed it's the price I have to pay for the convenience of transporting both audio and video over a single cable...

Well, I finally found the manual buried deep within the dell website and found out that the dock only supports two displays at a time. :( Thanks.

Except for recent (5/6xxx) ATI chips there aren't any mass market GPUs that can drive more than 2 displays at a time; I'm not sure if the mobile ones can do this or if it's only a desktop feature. The rest of us will have to wait for USB3 GPUs to show up (USB2 is too slow for anything other than a spreadsheet).

DVI can carry the same audio as HDMI... The most common failure is because by default TV's drop the outer 20/30 pixels of input and scale the rest up. The original reason for this was to hide analog broadcast timing issues of some sort. It's still done with digital TV because in the store Joe Moron will think the TV with the up sampled image looks better because the stuff he can see is bigger. X| X| X| X| The make HDMI work like a computer display option tends to be buried under 30 menus and cryptically named. :doh:

Basically, they use standard I/O cells instead of decent current controlled cells so they can't cope with the load presented by poor cables. Then each blames the other. I am picky about decent (not silly) cable construction.

I expected too much and hoped that DVI would be similar to USB in chaining devices. The problem is the dock can only drive two independent displays, so I had to purchase a USB graphics adapter. Thanks.

Right about that. But for my workplace, that would be sufficient. I can always use the primary display to render graphics intensive stuff. BTW, I bought one of these. I'll probably be receiving it in a couple of days.
