OK thanks for getting back to me,
The active Dual Link adapters, can I use the apple one that is bus powered?

use the apple MDP to Dual-Link adaptor which is USB powered

I am not as concerned about real time clock as it is just loops for an install,

YES YOU DO NEED TO ME CONCERNED!!... what I meant was that you need to ensure that the content is playing back correctly and check the expected length against a 'real-world' clock to ensure that it is not playing slow.
Or it may look glitchy and suttery if you are over-driving the system...
You should be especially concerned if you were considering syncing 3 different layers - how would you guarantee they were in sync and not skipping frames???

I just need to make sure all 3 screens are in
sync as they will form a vertical panorama so to speak.

a single layer running 1 video file assigned to 3 mixes will work.
The image in the 3 mixes need to be rotated, offset.
The mixes then need to be positined to lineup with the X4 window settings.

Sync IDs should be fine internally I would hope.

wrong aproach... (see above)

In your experience, in terms of performance load on the machine, does it make more sense to play back 1 x 4k file and just split it up with offsets in the mix windows

yes
but 4K not required
3x 1920x1080 vertical screens = 3240x1920

or play back 4 x 1080? I have never been able to actually try this side by side and see yet, just curious

possible - but no point if you use the mix window approach...
