As an alternitave to the Daisy Chain connection mode, you can connect each TILE unit directly to the computer's graphics card via the Display Port connection.
The below picture demonstrates an example with 4 Tile units connected to 4 Display Port outputs on one GPU.
Resolution in this configuration:
As each single Tile unit has a resolution of 1920X1080, the total resolution will need to be calculated according to the number of Tile units you have.
In this example you have 4 Tile units in Portrait orientation, which means the total resolution will be 1920 X ( 1080 X 4 ) = 1920 X 4320
