This portion of the guide explains everything you need to know about HDMI 2.1 which is the recommended HDMI for PS5.
HDMI for PS5
The HDMI cable that’s included with your PS5 is the recommended one you use. But if you need a new one or want another one, use any Ultra High Speed HDMI Cable that supports HDMI 2.1. A standard HDMI cable works but isn’t ideal, especially if you want to future proof.
What is HDMI 2.1?
HDMI 2.1 is the most recent update of the HDMI specification and supports a range of higher video resolutions and refresh rates. According to Sony, “The PS5 supports the HDMI 2.1 specification. HDMI 2.1 supports 4K 120Hz, but HDMI 2.1-compatible 4K TVs have not yet fully penetrated the market.”
Tip: How to Avoid Mixing Up Your PS5 HDMI With Other HDMI Cables
If you have a lot of consoles set up and/or share a space with others you may find yourself unplugging consoles or switching HDMIs often. At a glance, the HDMI cable that comes with your PS5 doesn’t look vastly different than any other HDMI cable. Avoid mixing up the cable by adding a cable tie or putting washi tape on both ends to denote it.
