there are “phony” HDMI 2.1 ports in devices because specific features of the latest standard are optional rather than mandatory. That said, HDMI performance is linked to the cable you utilize just as much as it is to the port. The logical question that arises is whether you can rely on the cables that are included with your media devices, such as the HDMI cable packaged with your PlayStation 5. Is it compatible with HDMI 2.1 for supporting high-resolution and high-refresh-rate, or should you replace it with a different one?
The brief response is yes, the PlayStation 5 is equipped with an HDMI 2.1 cable. This allows you to fully leverage your TV’s — and the HDMI standard’s — top features. This is especially crucial for the PlayStation 5 and PlayStation 5 Pro, as you can utilize features like variable refresh rate, high-frame rate modes with 120Hz, 4K and 8K output, optimized HDR and color configurations, and Auto Low Latency Mode (ALLM). Additionally, it is significant which HDMI port you select on your TV — ensure it’s connected to the correct one, specifically a port that supports 4K resolution and 120Hz refresh rate.
