LG OLED C5 77 outperforms the older Sony Bravia A80L 77 with 1300 nits peak brightness versus 800 nits (RTINGS), faster 0.1 ms response time, and newer webOS 25 interface. The A80L retains an edge in acoustic surface audio but trails in HDR impact and gaming features. The C5 is the stronger choice for most buyers in 2026.
