How do I connect an HDMI device and what cable version is required?

Connect the HDMI device to the HDMI/DVI IN 1, HDMI IN 2, or HDMI IN 3 jack on the TV, then select the corresponding HDMI input source using the INPUT button on the remote control. You must use an HDMI cable version 1.3 or higher — if the cable does not support HDMI version 1.3, flickering or no screen display can result. LG recommends cables under 10m in length, and an amplifier or repeater for longer runs. (Page 29)
