Hi guys - i have an acer ferrari 3200 laptop, and a 19inch acer 4ms gaming screen. Thing is, i want the 19inch external lcd screen to be my 2nd monitor, so the laptop inbuilt screen is the primary display.

However, when i setup dual screen, no matter what i do, the box for "make this my main display" is checked and greyed out for the external monitor and i cannot click it for the inbuilt screen - which has turned to screen 2.

Can anybody offer any advice as to how to rectify this problem, Im running vista business!

Thanks

Andy
