77-Inch OLED 4K 120Hz Smart TV

The Samsung QN77S85FAEXZA is a 2025 OLED TV with a 77-inch panel, 3840 x 2160 resolution and a native 120Hz refresh rate. The NQ4 AI Gen2 processor uses 20 neural networks to upscale content to 4K and optimise audio. It includes Wi-Fi 5, Bluetooth, four HDMI inputs, two USB-A ports and an optical audio output. A 2.5m Austere V-Series HDMI cable with ARC technology and silver-plated conductors is bundled.

Who this suits and who should look elsewhere

Viewers who want self-emissive OLED contrast, Pantone-validated colour and AI-driven 4K upscaling in a large-screen format will appreciate this screen. Gamers needing 120Hz motion clarity and VRR support via HDMI 2.1 features are also well served. Buyers who need more than four HDMI ports, analogue audio outputs or a built-in ATSC 3.0 tuner should consider other models. Those requiring a smaller footprint or a lower peak brightness for a darkened room may prefer alternative panel technologies.

The specification that decides fit

The 77-inch OLED panel with a fixed 3840 x 2160 resolution and 120Hz refresh rate is the single determinant. If the viewing distance, wall space and content workflow match a 77-inch 16:9 canvas at 4K 120Hz, this bundle delivers the required pixel density and motion performance. If the installation demands a different diagonal, a higher native refresh rate or a non-OLED surface, this is not the correct part.

Questions about this item

What source devices or content do I need to take full advantage of the 3840 x 2160 resolution and 120Hz refresh rate?

You need a 4K-capable source such as a streaming stick, games console, or UHD Blu-ray player that can output 3840 x 2160 at 120 frames per second, connected via one of the four HDMI inputs.

Will my existing HDMI cables and soundbar work with the four HDMI ports and the included Austere 2.5m cable?

Yes, the four HDMI inputs accept standard HDMI cables, and the bundled Austere 2.5m V-Series cable supports 4K HDR with ARC so your current soundbar will pass audio back through the same connection.

How can I verify the TV is actually running at 120Hz and showing HDR after I set it up?

Open the on-screen information banner or the connected device's display settings; it should read 3840 x 2160 at 120Hz with an HDR indicator when playing compatible content.
