To an HDTV, and have dual displays for my computer? For example, I want to plug my MacBook (in clamshell) into a Thunderbolt display on my desk, and have an HDTV mounted on the wall near my desk for others to view. When watching movies through netflix or showing people Youtube videos, I could then continue whatever I'm doing on the Thunderbolt display while they could see whatever I was showing them on the other. I hope that made sense... Thanks in advance!
