HDMI signals run at a very high frequency and are especially prone to errors caused by bad
video connections, too many adapters, or excessive cable length. To avoid the loss of an
image or jitter, follow these guidelines:
• Do not exceed 16.4 feet (5 meters) on the input of the transmitter or the output of the
PowerCage FOX SR HDMI scaling receiver.
• Use only the cable designed for HDMI signals that is supplied by Extron.
• Limit or avoid the use of adapters.
• Use only cables specifically intended for HDMI or DVI signals. Use of non-HDMI or
non-DVI cables or modified cables can result in a missing video output.
