The LG B4 OLED 77" takes the win for movie enthusiasts due to perfect contrast and larger screen size, beating the Hisense on black levels by an infinite margin per RTINGS tests. The Hisense U8N 65" counters with 2000 nits brightness versus the LG's 800 nits, making it better for daytime sports. At similar price points the LG's extra 12 inches and OLED panel give it the edge for most living rooms.
