Matrox QuadHead2Go Q185 DisplayPort 4K to 4x HDMI Video Wall Processor
The Matrox QuadHead2Go Q185 Appliance is designed as a standalone and compact videowall processor. Its purpose is to take a single, very high-resolution video signal and distribute it across four displays. It accepts a DisplayPort 1.2 input, supporting resolutions up to 4K at 60Hz. This single source is then split into four individual HDMI outputs, each capable of displaying up to 1920x1200 at 60Hz.
It offers great flexibility in videowall configuration, supporting standard layouts such as 2x2, 4x1, or 1x4, in addition to enabling non-rectangular or "artistic" arrangements. It incorporates advanced image processing functions such as scaling, content cropping, bezel management for smooth visual presentation, and the ability to independently rotate each of the four outputs by 90, 180, or 270 degrees.
It includes a Gigabit Ethernet (RJ45) port, which facilitates remote management and firmware updates using the Matrox PowerWall software.
