To truly get the most out of the latest generation of game consoles, a high-end 4K TV featuring HDMI 2.1, a variable refresh rate, and 120Hz options is the minimum. 8K usually has all these features plus upscaling of 4K signals to 8K, creating even better experiences. If you use an 8K TV as a monitor for a powerful gaming computer, true 8K gaming may come sooner, as gaming computers tend to evolve more quickly than consoles.
