I can't decipher what you said before "cause I have 2 spare monitors at home" but I can tell you that you won't get a definitive answer here. The reason is that embedded video solutions are all tweaked for each OEM's specific needs. Each laptop does multi-display with external monitors slightly different depending on the OS, the BIOS and the hardware configuration. Also, you didn't specify what kind of graphics is in yours so we can't even tell whether it's a decent one or some crappy El Cheapo solution. :P
