Overview
This document outlines possible input resolutions and configurations that can be used
with Matrox QuadHead2Go products. This document considers only the configuration of
the outputs of QuadHead2Go (not source capabilities, project type, or use case).
The possible configurations outlined in this document use monitors with a resolution of
1920x1080. For configurations that use other resolutions, contact
[email protected].
For configurations not outlined in this document, see Appendix A: Logical
arguments.
Note: This guide uses pre-set logical arguments to determine a possible configuration
that minimize the number of differing source output resolutions.
Matrox makes no guarantee about the accuracy of information contained in this
document. The user is responsible for validating the configurations outlined in this
document based on use case, source capabilities, and any other factors that may or
may not impact their video wall.
