I have a MacBook Pro Core Duo 2.4GHz (MB470xx/A) with OS X 10.6.4 (Snow Leopard). I am trying to add a second 1920x1080 display. (Currently one display using the native DVI-D out is working just fine.)
Going back in tech a few years I resorted to buying a Villagetronics VTBook PC Card. This card has DVI-D out and supports 1920x1080 resolution (its a 32MB Trident video card). I am using a Rosewill ExpressCard to CardBus Adapter to slot the VTBook in.
When hooking up the card I get the message:
Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.disabled.
After a short while both the PC Card and the ExpressCard adapter get very hot to the touch.
At no time am I able to configure a second monitor.
I have installed the Villagetronics OS X drivers for the card and I have tried both hot swapping and inserting the card with the MacBook Pro turned off (the requirement for getting this device to work under Tiger on PowerBook models).
