I have a Acer Aspire One with a 945 graphic card, the standard screen runs great, no problems there!
But when i plug my 7" touch screen in the VGA port and set the resolution at 800x600, it works great untill i restart, then just after boot up it automaticly sets the resolution at 1920x1200 at the external screen!
It boots at the right resolution (800x600) and u can just see the icons on the desktop for a split second before it changes the resolution so i think its a software issue?
This only happens when i use the external screen as the main/only screen, not in clone mode or just the standard screen.
The computer i just formatted and i checked all the drivers and settings etc, i dont know what to do next =S
