77-inch OLED TV bundle with full-motion mount

This package pairs a 77-inch Samsung S90FA 4K OLED Smart TV with a Kanto PMX800 full-motion dual-stud wall mount. The TV delivers 3840 x 2160 resolution at 120 Hz, AI-powered 4K upscaling via 128 neural networks, OLED HDR+, Dolby Atmos with OTS Lite and Q-Symphony Pro, and runs the Tizen smart platform. It suits viewers who want premium contrast and smart features in a large-screen format.

Wall mount installs on dual studs

The Kanto PMX800 mount attaches to two wall studs and extends 18.3 inches from the wall with a 2.2-inch retracted gap. It supports horizontal offset of 11 inches either direction for lateral centring, while oversized brackets allow vertical height adjustment. Installation requires locating and drilling into two studs; concrete or single-stud walls are not compatible without additional hardware not included.

Check stud spacing, VESA pattern

Verify your wall has two studs spaced to accept the mount's bracket width and that the TV's VESA pattern matches the supplied brackets. Ensure a power outlet and, if desired, a wired Ethernet connection are reachable at the planned mounting height. The mount supports panels up to 120 inches and 26 to 55 inches for the M600 reference, so confirm the 77-inch display falls within the PMX800's rated capacity.
