A:Answer Hello Chuck,
Yes, you can pass through 4K using this AV receiver to your PlayStation 5. Be sure to use a High Speed HDMI Cable with Ethernet. When you use high bandwidth video formats such as 4K/60p 4:4:4, 4:2:2 and 4K/60p 4:2:0 10 bit, a Premium High Speed HDMI Cable with Ethernet, which can support bandwidth up to 18 Gbps, is required.
