The Datapath VQS-01 is a display wall controller which connects to the VGA output of any PC and displays the image across 4 displays. Each display shows 1/4 of the VGA image in a 2 x 2 format.

The VQS-01 also supports display mirroring. This allows each output to be mirrored horizontally and vertically. This feature is particularly useful for display walls using LCD panels, allowing each panel of a 2 x 2 wall to be mounted in a different orientation. Many LCD panels have larger borders on two of the panel edges, by changing the orientation the minimum gap between displays can be achieved.

These adjustments allow the output display to line up exactly with the incoming analog VGA source. Adjustments to any particular display mode may be saved, the VQS-01 will then recall the settings every time the display mode is detected.
