Active HDMI cables may not be fully compatible with some Apple® adapters. An Apple® adapter may not supply the sufficient voltage for the chipset in an active cable and it also may prevent bi-directional HDCP communication between source and display. Please use our passive HDMI cables for applications where an Apple® adapter may be used.
