I have a 60-inch plasma television connected to my laptop's docking station (port aggregator) by way of a USB-to-HDMI converter. In the following Settings dialog, it is identified as display number 3:
I have a subscription to NBCSports.com where I use Mozilla Firefox to stream live and recorded content. So that I can watch the videos on the 60 inch screen, I select the USB to HDMI speaker for audio output…
