open the AJA Control Panel. The top menu selection is CONTROL. Make sure that TEST PATTERN and bars are selected. Now select the FORMAT tab. Change the display to various selections – like 525, 720, 1080, and 29.97, or 59.94 (and even the dreaded 23.98). Do any of these give you a picture ?
And bypass the breakout box – use the short mini HDMI to HDMI cable they gave you, and go from HDMI out on the card directly into the TV.
You have to make things as simple as possible to determine your problems. If you say “that short cable they gave me does not reach the TV” – then pick up the damn MAC Pro, and stick it right next to the TV, to make sure it’s not your cable, or the Breakout box.
