External Video Card

I am using a MAC AIR for my Boinx configuration. Unfortunately the GPU is not powerful enough for some effects. If I use a Sonnet Echo Express could I add a video card that Boinx would recognize?

To be honest, we haven’t tried this. However it should work, if MacOS-X is recognizing the graphics card in the Sonnet Echo Express and uses it as a secondary monitor. You have to configure this secondary monitor to be the main screen (move the menu bar in the Display System Preferences to this monitor) in order to let BoinxTV use it to render its video content.
