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.
I just put an 85" in my basement. That thing is annoying enough that it can stay with the house if/when I move. A 98" TV seems like it would be impossible to get down the same flight of stairs. If I upgrade again in this house it will 100% be a projector.
