You use the USB connector to initialize the monitor on your network; after that you can control the monitors using the supplied software via the Ethernet connector. This allows you to adjust the monitors' brightness and color as well as select the monitors display mode - video or scope view. The SmartScope Duo 4K also incorporates a Tally display around the border of the image, which works with industry standard Tally systems. The unit takes up three rack height units, but is less than two inches deep (including the connector depth), which makes it well suited for use in production trucks where space is at a premium. The unit also automatically flips the image if you need to install the unit upside down.
Note: SmartScope Duo v1 and v2 are functionally identical, with v2 containing a slightly different internal component set.
