Greetings! I live in a blended family (I use mac , roommate uses pc - haven't converted her yet). She and I would like to live in harmony and use a shared desktop workstation. I've hooked all external components (mouse, keyboard, printer) via USB to a Lenovo K33415 Port Replicator. NEC AccuSync LCD also connected to Port Replicator via VGA. When I plug her PC in, it recognizes all components immediately. My MacBook recognizes all components except the monitor. Do I have to use a Mini DisplayPort to connect the monitor to the Mac? Or can I make it work as is with the USB? Thank you sooooo much!!!!
