Build your wall with the touch of a button

Matrox QuadHead2Go on-device buttons

On-device buttons make it easy to select and set the display layout—simply cycle through pre-set configurations. 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.

Smallest footprint. Highest density.

Drive up to four Full HD displays from a single video signal from a single PCIe® card. A native network jack on the card eliminates reliance on the host computers’ network. PC independence means there’s no need for a driver and no system bus data transfer is required or executed—only power is taken from the host system’s PCIe bus. QuadHead2Go cards can be placed into available slots in existing systems without compromising system integrity and stability, and make minimal power consumption demands of the PC system.

Scale your video wall. Easily and infinitely.

Rotate and position outputs independently from one another

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.
