Also, my display was recently swapped, prior to this I had a REV A00 display (the A01 fixes sleep issues) - I managed to get collage mode working with the A00 display using the same drivers - but still, depending on which order of the screens I chose (in collage and extended mode), the machine would simply reboot, indicating that there are still issues to be resolved. Also, there is a new beta driver mentioned here https://communities.intel.com/thread/53655?sr=inbox which seems to properly identify the tiled displays as a single display so there's no need for extended displays or collage mode. I still suspect there's some weirdness going on with high displays - but for those 4K screens, properly identifying the screen as a single display is the right direction to go in.
