Capable of driving four displays from one signal, the Matrox® QuadHead2Go™ Q185 multi-monitor controller appliance provides complete video wall scalability and flexibility. This system-independent appliance is designed to power any video wall configuration of any possible dimension, from any DisplayPort™ video source—reliably delivering flawless image quality across expansive video wall displays, suited for control rooms.
- Drive up to four pristine quality Full HD displays from a single video signal—of up to 4Kp60 and 8Kx8K—at full RGB 8:8:8 and YUV 4:4:4 color support.
- 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.
Capture and display HDCP-protected content with QuadHead2Go multi-monitor controllers.
- 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 and media players with native DisplayPort™ 1.2 support.
- 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.
- 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.

Most luxury footwear uses EU sizing. Always refer to the designer’s fit notes, as sizing may vary slightly by brand and style.
How to Measure Your Foot
-
Place your foot flat on a piece of paper against a wall.
-
Mark the tip of your longest toe.
-
Measure the distance from the wall to the mark in centimeters (cm).
-
Match that measurement to the JP (cm) column in the chart above.
Example explanation you could place below the chart:
The JP column represents foot length in centimeters. If your foot measures approximately 25 cm, you would typically wear EU 39 / US Women 8. Because designer sizing can vary slightly, this method provides the most accurate reference when selecting luxury footwear.
