Yes a bit late here but check this site out. I have used this equiptment doing broadcasting. Matrox never gives me the blue screen of DEATH, so this might help you like it did me.If you are after a good dongle for running screens off your mac. you should try Matrox. www.matrox.com/graphics. I have been using the Matrox Dual Head 2 go. DP Edition. I have had no problems in the last 4 months using this dongle running from my MBP 15" mini dvi output to hdmi dongle. It then splits hdmi to my two 24" benq monitors and bingo, you win. peace
