This cable does not
mirror an image on two displays. It allows you to have two displays connected to one source (i.e. projector and monitor) and to use one display or the other without having to connect or disconnect the cables which can lead to connector stress damage.
This splitter cable is precision made with fine materials. The connectors are double enforced with PVC jacketing to prevent stress fractures in the conductor circuit. All interfaces are gold-plated to prevent corrosion and to increase conductivity.
Depending on your cable configuration, you might need a Distribution Amplifier if you want to mirror your A/V on two or more displays.
