Overview
Faster gaming sets apart the Hisense 55U7SF, a 54.6-inch 4K Mini LED Fire TV with 165 Hz support. Mini LED Pro, full-array local dimming, Dolby Vision Gaming and HDR10+ Gaming give it a strong feature base. Gaming reaches 48 Hz - 165 Hz (hertz) through AMD FreeSync Premium Pro, VRR, ALLM and four HDMI 2.1 inputs. Fire TV, the Hi-View AI Engine Pro and 2.1.2 CH 50 W audio cover streaming and sound. The 55-inch sheet lists IPS-ADS Pro, unlike the VA panels on the 65U7SF and 75U7SF. Brightness, contrast and dimming-zone counts are not published, so HDR output cannot be ranked. With the stand it weighs 17 kg (kilograms). Buy it if you want four HDMI 2.1 inputs and 48 Hz - 165 Hz Mini LED gaming; skip it if published brightness measurements are required.
