Laptop with two external monitors

Hey guys,

So I got a T60 Thinkpad with a docking station.  The docking station has a DVI port.  I got a DVI splitter for two external monitors.

Is it possible to use it the way to extend those two external monitors together?  Currently they both show same thing.  

Please advise.  Thank you!!

your docking station has to be able to support two individual monitors, if you want them to do anything other than display the same things (mirroring)

in this case, it doesnt... so you might want to pick up a usb vga adapter, it will add a "second video card" to your system, then just plug the second monitor into that (and the first into the dvi port on the replicator)

How about the 1st monitor into the DVI port on the replicator (this is what I have now), and

2nd monitor via normal VGA port on the replicator?  Would that work?

B HCommented:
the dvi and vga ports combine to the one video output the replicator pushes video out of

if you connect one to the dvi, and one to the vga, you'll see the same thing on both monitors (not independent of each other)

there are 2 ports just for convenience, not for functionality

You will need additional hardware to do that with 2 external monitors. You can have dual monitors by using the laptop screen for one and an external monitor for the other.

I dont know that particular port replicator/ docking station but i certainaly get dual screens in full functionality when using my Dell laptop on a Dell docking station. One screen in the DVI and one in the normal VGA works great for me.
Try it and see what your graphics properties shows when set up like this.

Edbedb, so can I use that way with a DVI splitter?  Or 1st on DVI and another on VGA?  Or do I still need an USB to DVI adapter?

with that port replicator, whatever is connected to the dvi port will show the same as whatever is connected to the vga port

you can plug in 3 monitors if you want - 2 on a dvi splitter and one on the vga - all three will show the same mirror as each other.

OK so I guess the only option I have is the USB to DVI adapter.   Correct?

You can use the laptop screen and one external screen for any useful dual monitor configuration.
bryon44035v3 is correct about what you will need to use 2 external monitors in that way.

I connected the 2nd display to the VGA and it doesnt even see it.  Black screen.....

So I guess I need that USB to DVI adapter.

you are better off getting a usb or or PCMCIA video card.

Are you sure the DVI and VGA don't operate independently?  I have only encountered one docking station that didn't let you use both ports for a two monitor display.

Hope the following isn't too basic: try
1) plugging a monitor into the DVI and VGA ports
2) rebooting (assuming this is WinXP?)
3) under Display Properties -> Settings do you see one monitor, or two monitors?  Sometimes the 2nd monitor is greyed out and set to a tiny box (compared to the first).  It will have a number '2' in it.
4) If you have the 2nd monitor, click on it and look for a checkbox 'Extend my Windows desktop onto this monitor'.  This can take up to 15s but you should get a display on the 2nd monitor.
