What type of HDMI cable is recommended for connecting devices to this TV?
The manual recommends using a High-Speed HDMI Cable or a High-Speed HDMI Cable with Ethernet. The cable should have a thickness of 0.55 inches (14mm) or less, as using a non-certified HDMI cable may result in a blank screen or a connection error. Note that this TV does not support HDMI Ethernet Channel. (Page 15)
