Dual monitor display settings revert on startup

I run Vista on a laptop and have a 2nd monitor hooked up via a docking station.

I set my 2nd monitor (i.e. not the laptop screen) as my main monitor,
however, after every restart Vista always reverts back to the Laptop as the
main monitor.

How can I stop Vista reverting backto the Laptop as the main monitor?

(This happens aven though at no stage have I un-docked the laptop!)

This happens with my twin monitors, and somebody else here mentioned the
same thing when using a laptop just a couple of days ago. It seems to be a
common problem with Vista, but I have never seen it happen in XP.

If you had twin monitors you could swap the cables around every time it
happens, but as you are using a laptop, using UltraMon will be the only
solution that I can think of. It allows you to change the primary monitor
very easily.

We've had this problem quite a lot on XP and it was todo with a graphics
chipset control panel option which overwrites the windows settings after a
reboot. If you want the change to be permanent you need to setup the dual
monitor in the chipset control panel.

Not sure if its the same as this was XP but sounds a lot like it.

I have used many dual-head XP systems over the years, but have never seen it
happen, with Matrox, ATi and nVidia GPUs. I have seen it happen on the only
two Vista dual-head systems that I have used, including my own. It does not
happen on that same computer when booted into XP. I also cannot remember
there ever being a way to choose which monitor is primary either (ATi FireGL
and nVidia QuadroFX) on the Vista drivers.

The software for my video card has a box to "automatically detect monitor"
and another one "manually select monitor". Now this is on a desktop computer
but on the off chance that your video card has the same choice it might be
worth taking a look for.

Thanks Ron! I'll give it a shot.
