In order to setup your system to incorporate several displays, each receiving a signal from your computer, you will need to connect your PC to a VGA splitter.
This will allow you to connect your displays into one central unit, with each display receiving the same image.
The below diagram illustrates this setup:
Please note the above diagram includes an active splitter. This is a splitter unit which requires its own power supply. These units are generally more expensive than passive splitters, but allow the display devices to identify themselves to the VGA source (which can help with resolution issues). We do not recommend using a passive splitter; although cheaper, they have no way of communicating with the display devices and usually are only able to offer VGA 2 outputs.
Promethean does not support the setup or maintenance of a VGA splitter, or its configuration.
