Something I posted over on LAFCPUG of my findings:
I just tested the new driver out, and it worked perfectly. Who’d a thunk! I use the Matrox Mini. I hooked up a Sony 40″ HDTV. Great picture! What I found really really interesting is that the footage looks the same on my computer monitor (The viewer in FCPX) as it does on the HDTV. I never did any color calibration yet. Also when scrubbing/playing “small filmstrips views”, and scrubbing/playing the footage in the “Project Library”, you can view it on your HDTV… Nice!
Be sure to follow the steps in the Matrox driver documentation when setting up… Happy Broadcast Monitoring!
