This High Speed HDMI cable with Ethernet supports resolutions up to 3840 x 2160, though it is not confirmed 4K-UHD-ready and does not include the extended feature set (HDR, ARC, 3D) found in our dedicated 4K HDMI 2.0 line. For guaranteed 4K, HDR, and ARC support, choose a cable from the 4K HDMI 2.0 line instead.
