Hisense's flagship Mini-LED splits its four HDMI ports by tier: HDMI 1 and 2 are full HDMI 2.1 at 4K@144Hz with VRR and Dolby Vision gaming, while HDMI 3 and 4 are HDMI 2.0 at 4K@60Hz. eARC rides on HDMI 3, so you can run two consoles on the 2.1 ports and still feed a soundbar. An ATSC 3.0 tuner, Ethernet, optical audio and USB round it out. This series is sold only in 75-inch and 85-inch sizes.
