I had similar trouble with the ATEM. I have had great luck with late model macs (mini display port and upwards, but not all. You will need a model with a dedicated video card also.

The problem is getting the exact signal right, you have to output a 768×576 signal refreshing at 25hz and interlaced. this is outside of what many video cards want to do. Sometimes using tools like switch resx or powerstrip will allow you to get a picture to the unit.

I had almost no luck with PC connections and blackmagic tech support have stopped responding about this issue fullstop (to me anyway).

There are definately some strange things going on with the firmware at SD, certain firmwares will give me blue and red switched for some computers and not for others, other firmwares report the edid correctly and will have computers that could not work on another version work.

Please hassle blackmagic support to sort out the SD modes! I know I ma not the only one, and I am sure a lot of the problems are with the firmware (even though they give next to no documentation on fixes and changes when they do a release) as each release behaves so differently. Anyway for Sd I am having the best luck with version 2.5-2.7

Cheers
