Re: [Thinkpad] A20m 2628 multiple monitors & extended desktop

This was discussed here before
http://zurich.ai.mit.edu/hypermail/thinkpad/2001-01/0181.html ; in fact
member Bill Armstrong reported his own A20 experience. However, the
less-than-encouraging responses were made over 2½ years ago, and there've
been plenty of new and updated drivers for Win2000 since then.

Dell Latitude owners who had to get their Rage Mobility drivers from IBM had
similar problems; one said that the solution was to uninstall all previous
video drivers and then install the current IBM Rage Mobility driver.

Other suggestions:

If you haven't already, check your monitor model on the Win2000 Hardware
Compatibility List
http://www.microsoft.com/windows2000/professional/howtobuy/upgrading/compat/
search/devices.asp

Your video adapter is listed as one that may need updated drivers from the
manufacturer.

A snippet from
http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechn
ol/windows2000pro/reskit/part3/proch10.asp :

Video Devices
You can use the multiple monitor feature with a docked portable computer,
but only if the docking station allows you to install Peripheral Component
Interconnect (PCI) or Accelerated Graphics Port (AGP) display adapters.
Also, the on-board display adapter (the one that is a part of the portable
computer's motherboard) must be designated as the VGA display device. This
is usually not a problem, although some BIOSs allow you to choose which
display adapter you want to use as the VGA device. In this case you must
designate the on-board display adapter.

Windows 2000 does not support hot undocking of portable computers while they
are using multiple monitors. If a portable computer is using multiple
monitors and you want to perform a hot undock, you must stop using all but
one of the monitors and then undock. You can do this by detaching the
secondary display before performing the hot undock.

To detach a secondary monitor

From the Start menu, point to Settings, click Control Panel, and then

double-click the Display icon.
In the Display Properties dialog box, click the Settings tab, double-click
the secondary monitor, and then click Attach.
Click Apply to detach the monitor. The secondary monitor should turn off ,
leaving the primary monitor running.
After you have detached the secondary monitor, you can perform a hot undock.
