Like most of the other best Samsung TVs, the new 98-inch QN900C has Samsung’s Gaming Hub and Motion Xcelerator Pro. That delivers 4K at up to 120Hz, rising to 144Hz with compatible PCs. There’s also support for AMD FreeSync Premium Pro as well as NVIDIA G-Sync like most of the best gaming TVs have.
My TV hasn’t been connected to the internet except for very specific updates I preemptively researched what they included. Otherwise it’s a „dumb TV“.
