Logical argument A. If (Columns are Even AND Rows are Even)

Examples 2x2, 2x6, 4x4, 8x8, 10x42, 20x20, 50x50, 100x100, etc.

# QuadHead2Go units

# GPU outputs Same as # QuadHead2Go units.

Place all the QuadHead2Go units in a 2x2 configuration.

Ensures the least number of inconsistent resolutions from the source to the QuadHead2Go units.

None.

Logical argument B. If (Columns = 1 OR Rows = 1)

Examples 1x2, 3x1, 5x1, 17x1, 27x1, 1x100, 250x1, etc.

If rows = 1:

Place each QuadHead2Go unit in a 4x1 configuration. The right-most single monitor is a direct 1920x1080 output from the source.

If columns = 1:

Place each QuadHead2Go unit in a 1x4 configuration. The bottom-most single monitor is a direct 1920x1080 output from the source.

Example:

If rows = 1:

Place each QuadHead2Go unit in a 4x1 configuration, except the right-most or left-most

QuadHead2Go, which will be in a nx1 configuration.

If columns = 1:

Place each QuadHead2Go unit in a 1x4 configuration, except the top-most (or bottommost) QuadHead2Go, which will be in a 1xn configuration.

Example:

A horizontal or vertical line is formed.

1x6, 6x1, 1x9, 9x1.
