I am trying to run two monitors going from my laptop(which is on a dock) to two displays, one VGA, one DVI. I don't want to use the Laptop LCD.
When I ever I try to select both monitors in windows screen proprieties and hit apply, it says these settings can not be applied. I can however, use one external monitor with the laptop lcd in a dual setup, just not the two external monitors and no laptop lcd.
It's a sony z series laptop, model number: VPCZ1390X
Any help would be great.
