77" OLED panel for AI-driven viewing

The 2026 Samsung QN77S90HAEXZA is a 77-inch OLED TV that uses self-illuminating pixels and the NQ4 AI Gen3 Processor to reach 4K resolution at 165Hz. Glare Free technology reduces reflections while 128 neural networks enhance picture and sound for streaming, live sports and gaming.

Suited to gamers and streamers seeking high

Buyers who need more than four HDMI inputs or a display smaller than 43 inches should consider other options. The included Walts mount fits screens from 43 to 90 inches and extends 31 inches from the wall, retracting to a 2.4 inch profile.

165Hz refresh rate decides gaming fit

Motion Xcelerator 165Hz, VRR, FreeSync Premium Pro and NVIDIA G-SYNC compatibility are built in. If the source device cannot output above 60Hz, the panel's headroom goes unused.

Questions about this item

Does the 77" OLED TV ship with the Walts Full Motion Mount and the 6-outlet surge protector, or must I buy them separately?

What does the 165Hz refresh rate actually deliver when I connect a PC or console to the four HDMI ports?

Motion Xcelerator 165Hz drives the panel at up to 165 frames per second with VRR, FreeSync Premium Pro and G-SYNC support across all four HDMI inputs for tear-free 4K gaming.
