Dual monitors and dock

[sbddude]

I am trying to set up dual monitors using an external display connected via the dock and the thinkpad's internal LCD (SXGA+).

I would like to do the following:

1. Make the External display be the primary screen.

2. I would like the external display become the primary screen when the computer is placed in the dock, and then the internal LCD become the primary screen when not docked.

I searched and am not able to find any answers.

This is how I usually run my setup when I'm at school. I'm not sure the stock video drivers can do it, so you should get the omega drivers (http://www.omegadrivers.net/)

Once you have that installed, make sure everything is plugged in and the laptop is open then go to Display Properties -> Settings tab -> advanced -> Displays tab and press the little blue 1 button under Panel with the picture of a laptop.

Windows handles screen switching ok, but if you want more control I'd recommend Ultramon (http://www.realtimesoft.com/ultramon/)

thanks for the suggestion. I tried ultramon however, i am unable to set the primary monitor away from the internal LCD.

Oh, I made a mistake in what I said before. The number under the internal lcd should be 2, not 1.

Are you using the omega drivers?

In the Display Properties Settings tab, click Advanced ( button), even teh ATI drivers have a "Displays" tab which allows you to determine which monitor is the primary. Little [1][2] buttons for each display ... see them?

I do this all the time on my T41 with ATI drivers (though I run Omega drivers on my own T43).
