Overview

The QN77S85FAEXZA is a 77-inch OLED TV from Samsung's S85F line, built for 4K UHD with a 120Hz refresh rate. It runs Tizen smart TV software with Bluetooth, Ethernet, HDMI, USB and Wi-Fi connections, in a 63.5 lb Graphite Black chassis.

OLED at 77 inches sits at the larger end of what Samsung offers in this panel type, and the 120Hz refresh rate matters most for game consoles and fast sports broadcasts rather than everyday viewing. Tizen ties the set into Samsung's own app and remote ecosystem, which some buyers prefer over Google TV or Fire TV. The 63.5 lb chassis means this is a wall-mount or stand install rather than a shelf TV.

Who it's for

Performance notes

OLED panels use per-pixel dimming, so black levels and contrast are typically stronger at this size than an equivalent LED panel, and the 120Hz refresh rate supports smoother handling of fast motion when paired with a compatible source. The 4K UHD resolution and HDMI input cover current game consoles and streaming boxes, while built-in Wi-Fi and Ethernet give a choice between wireless setup and a wired connection for steadier streaming.
