Toshiba M205S810 with external monitor/projector

Hi,

I am a teacher in a university. I just got a Toshiba M205S810 tablet pc and want to use it in the class room. Then I found something unexpected and don't know how to fix it.

Simply stated, the problem is: in the "clone" mode, the VGA output screen rotates with the LCD output screen.

Due to cable connection locations of this Tablet PC, I put the default screen orientation for tablet mode as "secondary landscape". Then, everytime I go to tablet mode, the output of the VGA port (my projector) turns upside-down.

I may understand that the VGA screen need to rotate with the LCD when in "primary/secondary portrait" mode. But shouldn't the VGA output stay at "primary landscape" when the LCD is in "primary/secondary landscape" mode?

Can this problem be fixed?

Thank you in advance for the help!
