Compaq Presario CQ40 Notebook PC VJ985PA#ABG 515AX?
I have installed Windows 8 - but now cannot use func F4 to switch to external monitor. I get "Your PC can't project to another screen, Try reinstalling the driver or using a different video card." How do I do this?
When I look in device manager it has Microsoft Basic Display Adapter.
