thanks for your reply. It is because I need it in a television studio. And I use today both screen output and video output card in the studio on the earlier version of the MacPro. Why we use the video card is besauce the tv system in denmark is PAL and that is 50 hz. But the output from the Macs DVI...

I just bought a brand new Mac Pro and want to put a black magic video card in it. But have been told that with the new models it can not use the video card as a extended desktop. Mac should have change this so it does not work on new mac - is it true??
