It is possible to use Display Port cables to interconnect up to 16 Tile units.
Each Tile has two Display ports, one “In” and another “out”. The Display Port “In” of the first Tile will connect directly to the computer’s graphic card, meanwhile the Display Port “out” will connect to the Display Port “In” of the second Tile. The Display Port “out” of the second Tile will connect to the Display Port “In” of the third Tile. You can repeat this interconnection up to 16 Tile units.
All the USB cables should be connected directly to the USB ports of the computer.
The following picture demonstrates an example of 4 Tile units, using the daisy chain mode.
Resolution in this configuration:
As each single Tile unit has a resolution of 1920X1080, after configured the daisy chain mode, the total resolution will be multiplied by the number of Tile units you have.
On this case, you have 4 Tile units in Portrait mode, which means the total resolution will be 1920 X ( 4 times 1080) = 1920 X 4320
