77-inch 4K OLED Smart TV

The Samsung S90FA series combines a 77-inch OLED panel with 4K resolution and a 120Hz native refresh rate. The NQ4 AI Gen3 processor drives 4K AI Upscaling Pro and OLED HDR+ for detailed highlights and deep blacks. Dolby Atmos and OTS Lite create immersive audio from the 2.1-channel speaker system. Tizen OS provides streaming apps and smart home integration.

HDMI ports and wireless connectivity

Verify that your AV receiver or soundbar supports eARC to pass lossless audio through the HDMI 2.1 inputs. The TV includes four HDMI ports, two USB-A ports, an Ethernet jack and dual-band Wi-Fi 5 with Bluetooth. Wall-mount installations require a VESA-compatible bracket rated for the display weight. Ensure your broadband speed can sustain 4K HDR streaming bitrates.

Upgrade from older LED or early OLED sets

Moving from a standard LED TV adds per-pixel lighting control for infinite contrast and wider viewing angles. The 144Hz Motion Xcelerator and AI Motion Enhancer Pro reduce blur for sports and gaming compared to 60Hz panels. Auto HDR Remastering improves legacy SDR content without manual tweaking. Buyers needing more than four HDMI inputs or a built-in ATSC 3.0 tuner should consider external switching solutions.

Questions about this item

Does the bundle include the Austere 2.5 m HDMI cable or do I need to buy a cable separately?

The bundle ships with one Austere V-Series 2.5 m Premium 4K HDR HDMI cable, so no separate cable purchase is required for the first HDMI connection.

Should I choose the 77 inch model or a smaller size for a typical living room?

The 77 inch screen delivers a 3840 x 2160 4K image at 120 Hz (up to 144 Hz) with OLED HDR+, making it ideal for larger seating distances where the extra diagonal fills the field of view.

What does the 144 Hz refresh rate actually give me when gaming on a console or PC?

Motion Xcelerator 144 Hz supports 4K 144 Hz variable refresh rate input, reducing motion blur and tearing for smoother fast-paced gameplay on compatible sources.
