Dual monitor setup problem

Hi folks!

So I just figured out that I can have my laptop hooked up to my TV via HDMI and extend the display mode so I can for instance, chat on the "computer side" whilst watching a movie/listening to music on the tv. I set the display mode(in system settings) to "Full Screen #2". Now I have a fully functional XBMC window on my TV and "Windows UI" on the built-in screen, which also functions as desired.

Now the problem is small, but I bet you guys could make my life a lot easier
So everytime I disconnect the HDMI from the laptop(I use the same cable to play PS3... sigh) and connect it again, I get the extended view to the TV as usual, but when I launch XBMC, it opens up in the laptop screen. I go to settings, and apply the "Display #2" setting and now I'm happy again.

Is there any way to have the setting always on Display #2 or is this some kind of system restriction and therefore impossible to act that way? I always hook the HDMI to laptop before launching XBMC...

I tried UltraMon and used some guide found on this forum, but it didn't seem to help...

Thanks guys, all info is highly appreciated!
