Introduction
Thank you for purchasing a StarTech.com VS420RDVIA DVI Video and
Audio Matrix Splitter/Switcher - 2 in x 4 out. With the Converge A/V DVI
Matrix splitter/switcher, you can select between two DVI-I sources on
multiple monitors (up to four). With the push of a button, the VS420RDVIA
lets you select what input you’d like on each display. Plus, the option to
independently toggle video and audio on/off for each display is also avail-
able.
This matrix splitter/switcher inludes IR control and an additional IR cable
sensor if you would like to hide the unit. The VS420RDVIA also includes
ear-mounts for 19” rack-mount use.
Please note: VS420RDVIA will not convert video signals. For example,
inputting a DVI-A signal to a DVI-D display will not work. Input signal must
be the same as output.
