77-inch 4K OLED smart TV for home cinema

The Samsung QN77S85HAEXZA is a 77-inch 4K OLED television built for viewers who want deep blacks and bright highlights in a large-screen format. Its NQ4 AI Gen2 processor analyses each scene in real time to improve brightness, colour and motion clarity. Pantone-validated colour reproduction and Color Booster Pro deliver accurate skin tones and vibrant hues. The 120 Hz panel and Motion Xcelerator make fast action look smooth.

Upgrade from older LED or smaller OLED sets

This model replaces conventional LED TVs that cannot match OLED contrast, and smaller OLED panels that lack the same immersive scale. The jump is worth it when you watch HDR movies, play 120 Hz games or stream 4K content and want the combined benefit of per-pixel lighting, AI upscaling and Dolby Atmos audio in a single 2026 series. FreeSync Premium and AI Auto Game Mode reduce tearing and optimise settings automatically for gaming sessions.

Check wall space, mount pattern and connectivity

Verify that your wall or cabinet can accommodate a screen measuring 67.8 inches wide by 41.7 inches high and 13 inches deep with the included stand. The VESA mounting pattern is 400 mm by 300 mm. Ensure you have an HDMI 2.1-capable source for 4K at 120 Hz, a LAN port or Wi-Fi 6E router for smart features, and an eARC-compatible sound system if you plan to use Dolby Atmos passthrough.

Questions about this item

Will the 400 mm × 300 mm VESA pattern and 67.8-inch width fit my wall bracket?

The TV uses a 400 mm × 300 mm VESA mount and measures 67.8 inches wide, so verify your bracket supports that pattern and can hold the full width.

How do I connect the four HDMI inputs and the eARC port during setup?

Plug each source into one of the four HDMI inputs; use the eARC-labelled HDMI port for an audio receiver and enable eARC in the sound settings to pass Dolby Atmos.

When should I run the pixel-refresh cycle on the OLED panel?

The TV runs an automatic pixel-refresh cycle after four hours of cumulative standby; you can also start it manually from the panel-care menu if you notice image retention.
