What type of HDMI cable should I use for the best performance?

Samsung recommends using High Speed HDMI Cable, High Speed HDMI Cable with Ethernet, Premium High Speed HDMI Cable, Premium High Speed HDMI Cable with Ethernet, or Ultra High Speed HDMI Cable. Use an HDMI cable with a thickness of 17 mm or less, and use a cable shorter than 3 m to get the best UHD viewing quality. Using a non-certified HDMI cable may result in a blank screen or a connection error. (Page 21)
