A:Answer From Rtings.com: "The Hisense U6G and the Hisense U7G are very similar overall, with a few minor differences between them. The U6G has better black uniformity, but the U7G has better contrast, it's a bit brighter in SDR and a lot brighter in HDR. The U7G is also slightly better for gaming, with a higher native refresh rate, FreeSync support, and two HDMI 2.1 ports."
