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.
Projectors certainly have their limitations, but I really like that mine just disappears into the ceiling when I’m not using it instead of taking up my entire wall.
