The PlayStation 5 comes with an HDMI 2.1 cable. This is the minimum HDMI standard required for 4K gameplay at 120Hz. The HDMI 2.1 connection allows next-gen consoles to support higher frame rates up to 120 frames per second (fps) . The cable that comes with the PS5 box is of good quality. It is important to note that the PS5 has an HDMI 2.1 port at the back of the console, and any other standard of HDMI cable will not allow for the full support of 4K gaming at 120Hz.
