Expand to a video wall configuration of any size by using multiple QuadHead2Go units.

Create a video wall from any content source, including professional graphics cards and integrated GPUs, video wall controllers, digital signage players, media players, decoders, laptops, NUCs, set-top boxes, gaming consoles, and more.

Design modern and artistic video wall layouts with free rein - Each output can have its own resolution, be independently rotated (90, 180, and 270 degrees), cropped, upscaled, downscaled, and positioned anywhere.

Fashion countless forms of setups - Arrange displays in 4x1, 1x4, 2x2, 3x1, 1x3, 2x1, or 1x2 rectangular configurations, in portrait or landscape, or other non-rectangular/artistic configurations—and combine/scale them to create large-scale, captivating video walls.

Simplify installation with guaranteed out-of-the-box plug and play when using the default configuration of 2x2 in landscape—set up without installing software or even connecting a video source.

Design any custom configuration/array with the intuitive Matrox PowerWall software.

Ensure compatibility with professional-grade graphics cards with native DisplayPort™ 1.2 support—no adapter required.

Eliminate physical handling by controlling and updating the units remotely from anywhere on the network (LAN).

Select and set the display layout by cycling through pre-set configurations* using an on-device button—there is no need to install software when using a pre-set configuration. *Pre-set configurations can be customized.

Set up display positions, fine tune bezels, and also troubleshoot with ease, by accessing the built-in or pre-saved images directly from the appliance, together with display identification information that includes the ID number and the resolution of each output.
