Displays are connected via standard DVI (if supported) or VGA cables (readily available up to 30"), and the use of an external VGA splitter allows several displays to be connected in parallel to the same PC, for example on different walls inside and outside of the studio (for long cable length high quality cables are recommended)
Interface to the on-screen displays is via an external USB GPIO interface (supplied), requiring external closing contacts. This also acts as a license, but any number of displays may be driven from the same PC using the same dongle, by using a suitable VGA splitter.
It is also possible for SID to be displayed on any same networked computer, meaning larger distances can be covered without the need for additional cabling.
