I feel like when i try to hook up my macbook to a monitor with the vga adaptor, it just never works smoothly. i always have to play around with the wires for a while until i have an image on the screen. plug out the usb mouse and keyboard, plug them back in, unplug the adaptor, plug it back in. then finally it works, and this is every time i try to do it. i prefer to to it with my laptop closed, not in dual screen mode. can anyone point me to a simpler process to do this? its getting really annoying
