HDMI® 2.1 is the most recent update of the HDMI® spec and supports eARC, a range of higher video resolutions and refresh rates including 8K60 and 4K120, and Dynamic HDR formats. 8K delivers a super-immersive viewing experience with 2x the horizontal and vertical resolution of 4K, and 4 times as many pixels; and combined with 60Hz refresh rate enables smooth and sharp viewing of content with high-speed action. HDMI 2.1 with 8K and eARC ensures your system is ready for the clearest and cleanest picture available both now and down the road.
