I have my external HD LCD monitor connected to my MacPro with both a DVI-HDMI cable from my Nvidia graphics card, and HDMI from the Intensity Pro. When monitoring FCP7 I can compare the output using both the Digital Cinema Desktop Preview and the Blackmagic HD output by switching inputs on the external display. I have noticed that the Blackmagic output is causing overscan (or a slightly zoomed in picture) that is not seen from the Digital Cinema Desktop Preview. From the Video Playback menu in FCP I am selecting the Blackmagic HD 1080i 59.94 (1920x1080) option. Is there any way to correct this, or are there some settings that I have overlooked?
