Ivojo supply a range of DVI switchers, allowing switching between multiple sources to one display. Some offer distribution of the output to multiple displays.
If you wish to take one source and send it to multiple displays, then take a look at our DVI Distribution Amplifiers or if you need to switch multiple sources
between multiple displays then look at HDMI matrix switchers or DVI matrix switchers.
Ivojo also offer an extensive range of DVI cables.
