Extending the HDMI connection using an HDMI amplifier/repeater
Although there is not an official limit on HDMI cable length (as it mainly depends on the quality
of the HDMI cable), in order to prevent potential display quality problems like interference and
ghosting, if you need to connect the display to a computer or an A/V device (such as a DVD or
Blu-ray player) over 5 meters, deployment of an HDMI signal amplifier is highly recommended.
1. Connect the HDMI input jack on the display to the HDMI output jack on the HDMI signal
amplifier/repeater.
2. Connect the HDMI input jack on the HDMI signal amplifier/repeater to the HDMI output
jack on the HDMI source device using an HDMI cable.
• Refer to the User Manual of your display for the location of HDMI input jacks.
• The HDMI cables and HDMI signal amplifier/repeater are not supplied and should be purchased
separately.
