the second problem cannot see vga output detected, thank in advance.

depending on sort of use want monitors, if they're not gaming/home cinema:

"if you're aiming 3 screens usb dvi adaptors, available under £50. these enable laptop generate third video output, have inherently low response time , suitable more static content - not video."
