Intel® Graphics Command Center loses the order of Displays once collage mode is turned off.
The numbering system and positioning for your displays gets re-arranged in the Intel® Graphics Command Center every time collage mode is turned off.
This is an expected behavior for 6th, 7th, and 8th Generation Intel Processors. The Intel® Graphics Command Center clones/mirrors all displays at the OS level. The persistence value is lost when the displays are un-collaged. With the Intel® Graphics Command Center, all displays are re-enabled out of collage so the displays need to be repositioned after collage.
