I'm new here so not sure where to post this but here goes. I've got a nvidia gtx 770 card and I would like to use a dual monitor setup. The card has an hdmi and displayport but my tv only has an hdmi port so I will be using a displayport to hdmi adapter. Now I want to have separate audio on my monitor and my tv to allow my brother to play games in the tv while I watch a movie on my monitor but can this be done if I connect a pair of usb headphones to my pc for the monitor sound and have separate sound for the tv speakers?
