77-inch OLED Smart TV with AI upscaling

The Samsung QN77S90FAFXZA is a 77-inch OLED Smart TV built for viewers who want deep contrast and AI-enhanced 4K picture quality. It includes a full-motion wall mount and a three-outlet surge protector in the bundle. The 120 Hz native panel supports up to 144 Hz motion processing for smoother sports and gaming. Tizen OS provides streaming apps and smart home integration.

HDMI 2.1 bandwidth caps 4K at 120 Hz

Four HDMI inputs accept 4K signals at 120 Hz, matching the panel's native refresh rate for consoles and PCs. The AI Motion Enhancer Pro can interpolate frames up to 144 Hz, though source content above 120 Hz is not passed through the HDMI ports. Wi-Fi 5 and Ethernet handle network streaming, while Bluetooth connects wireless audio. The 2.1-channel speaker system with Dolby Atmos and OTS Lite creates virtual surround without extra speakers.

128 neural networks drive upscaling headroom

The NQ4 AI Gen3 Processor uses 128 neural networks to upscale sub-4K sources to 3840 x 2160, preserving detail on streaming video and broadcast TV. OLED HDR+ and Auto HDR Remastering expand dynamic range within the panel's peak brightness limits. The 175 lb mount rating secures the 77-inch screen on VESA patterns from 43 to 90 inches. Ultra Viewing Angle maintains colour accuracy for off-centre seats.

Questions about this item

Should I pick the 77" S90FA or a smaller size for my living room?

The 77" panel delivers 3840 x 2160 pixels at 120Hz native refresh, so choose it when viewing distance allows the larger canvas to show the full 4K detail.

What does the 120Hz refresh rate actually give me in games and sport?

Motion Xcelerator drives the panel up to 144Hz, so fast-motion content stays sharp with minimal blur on the OLED screen.

Which HDMI standard do the four ports support and what resolution ceiling does that create?

Four HDMI inputs accept 4K signals at 120Hz, letting consoles and PCs run at the panel's maximum 3840 x 2160 120Hz without compression.
