The PS5 can support up to 8K resolution (though not until a firmware update arrives), which many players won't need on their 1080p TVs. Whether games will run natively in 8K is more of a question mark (we assume only the least graphically intensive titles will), but it means the console is future-proofed if you decide to buy a nicer TV down the line. In addition, the PS5 supports 120Hz refresh rates, allowing you to enjoy smoother games if they offer a higher framerate if you have a HDMI 2.1 compliant TV.
