Monitor position moves when I reboot; any way to fix that, or dynamically set it?

"The freeware Display Changer is a command-line utility that can configure all the properties of a monitor, including its relative position to the primary monitor.

For example, to move a specified monitor currently positioned on the right of the primary to the left of it:

dccmd.exe -monitor=""Dell 2009W(Digital)"" -left

As another example, to list all monitors:

dccmd -listmonitors

You could write a script that creates the preferred monitor layout, and set it to run automatically after login in Start menu / Programs / Startup."

"Sounds like you're in need of UltraMon's Display Profiles.

Display profiles make it easy to
switch between different desktop
configurations. A profile stores the
display mode, position and state
(enabled/disabled) of each monitor, as
well as which monitor is primary
(changing the primary is only
supported on Windows 2000/XP and
later).

If your computer is used by more than
one person, you can use display
profiles to set up custom display
configurations for each user. Whenever
a user logs in, his or her display
settings will be applied. Windows XP
Fast User Switching is supported.

UltraMon is not free (US$39.95 for a single license), but it is well worth it for the features."
