SAMSUNG QN77S85HAEXZA 77" 4K OLED Smart TV 120Hz 2026

77-inch OLED TV for home cinema and gaming

The Samsung QN77S85HAEXZA is a 77-inch 4K OLED Smart TV built for viewers who want deep blacks and bright highlights in one panel. Its NQ4 AI Gen2 processor upscales older sources to near-4K clarity while the 120 Hz panel keeps motion smooth for sports and fast-paced games. The set runs Samsung Tizen OS with built-in voice assistance and a Gaming Hub for cloud titles. Buyers who need a smaller screen or a lower refresh rate should look elsewhere.

Thermals noise and power in daily use

OLED pixels emit their own light so the panel runs cooler than traditional LED backlights and produces no fan noise during normal viewing. The 2-channel bottom-firing speakers with Dolby Atmos and Object Tracking Sound Lite deliver clear dialogue without external amplification at moderate volumes. Adaptive Sound Pro and Active Voice Amplifier adjust output automatically when ambient noise rises. The included 6.8 oz screen cleaner helps maintain optical performance without residue.

Build connectors and mounting day to day

The graphite-black chassis measures 67.8 inches wide by 13 inches deep by 41.7 inches high on its included stand and supports 400 x 300 VESA mounts for wall installation. Four HDMI inputs with eARC, two USB-A ports, a LAN jack, Wi-Fi 6E, Bluetooth, RS-232C and IP control cover most home-theater and smart-home integrations. Multi-View and Picture-in-Picture let two sources share the screen simultaneously. Installers needing 200 x 200 VESA or additional HDMI ports will require adapters or a switch.
