77-inch OLED TV with AI processor

This 2025 Samsung S90FA model delivers 4K resolution on a 77-inch OLED panel driven by the NQ4 AI Gen3 Processor with 128 neural networks. The bundle includes a Kanto R500 recessed full-motion mount and a screen cleaner. It suits viewers who want a large self-emissive display with integrated smart features.

120Hz panel with Motion Xcelerator 144Hz

The native 120Hz refresh rate supports Motion Xcelerator 144Hz for smoother motion handling during fast content. AI Motion Enhancer Pro and Real Depth Enhancer work continuously to optimise clarity. OLED HDR+ and Auto HDR Remastering maintain contrast and brightness across extended viewing sessions without the risk of permanent image retention associated with static elements.

Recessed mount with 2.2-inch wall gap

The included Kanto R500 mount achieves a 2.2-inch wall gap and provides swivel and tilt adjustment for sight-line optimisation. Installation requires a VESA-compatible wall structure and sufficient stud spacing for the 77-inch panel weight. The mount extends 18.3 inches but is rated for 26 to 55-inch displays, so verify compatibility before mounting this larger screen.

Questions about this item

How loud or hot does the 77" OLED panel get when it runs all day at 120Hz?

The TV uses an OLED panel that emits light per pixel without a backlight, so heat output stays modest even during extended 120Hz viewing; fanless design means silent operation.

Which wall structure and tools are needed to install the included Kanto R500 recessed mount?

The R500 requires a standard 2 x 4 stud cavity, a 2.2" recess depth, and basic drill, level, and stud-finder; it supports 77" screens up to the mount's rated capacity.

Will my older 1080p Blu-ray player and soundbar work over the four HDMI inputs?

Yes — the four HDMI ports accept legacy 1080p sources, and the TV's 4K AI upscaling with 128 neural networks will upconvert them; eARC on one port sends audio to an older soundbar.
