With shorter cables, this is often perfectly fine, short and cheap HDMI cables can usually hit the full bandwidth pretty decently. Especially with the PS5 which I think only can do 32Gbps bandwidth from the HDMI 2.1 port instead of the full 48Gbps, even a bit lousy Ultra High Speed cable should do fine. Conclusion . If you are a gamer - specifically a current-gen console gamer - and are in the market for a new TV, you should ensure your purchase includes a least one HDMI 2.1 port that supports 4K DisplayPort 2.0 seems to support "up to" 77 gbps, which using the HDMI's 48 Gbps at 4K120 as the base, would translate to getting 4K192. DisplayPort 2.1 seems to get 80 Gpbs so again, assuming 120 is the maximum on 48 Gbps using HDMI, then it should handle 4K200 fps. All of these capabilities seem to be lower than the 4K 240 hz screens coming out. Officially released in 2017, HDMI 2.1 took a very long time to become mainstream. The release of PS5 and Xbox Series consoles plus new graphics cards from NVIDIA and AMD made HDMI 2.1 mainstream because of the need to deliver 4K 120Hz with HDR and VRR. HDMI 2.1 represents a huge leap over HDMI 2.0, with 48Gbps in bandwidth compared to 18Gbps. 4K HDMI 2.0 cables deliver 4K at 60 frames per second (fps), while 8K HDMI 2.1 cables deliver 8K content at 60fps or 4K content at 120fps, since less data is required to transmit 4K content. The bottom line is that if you have 4K content, you’ll get twice the frames per second using an 8K cable. We’re talking real-time gameplay, low latency Try plugging the usb power cable for the switcher into a different usb port on the PS5. Try different HDMI cables from the ps5 to switcher and switcher to TV. Make sure they’re HDMI 2.1 certified and less than 10 feet long. If different cables don’t fix it, try resetting the TV to factory settings. If that doesn’t work, I’d RMA the switcher But using 2.1 on the Series S will still give you the benefits of dynamic HDR as well as improved color and subsampling. The other benefit of HDMI 2.1 is 8K support. Both the PS5 and Xbox Series X I have both series x and playstation 5. Xbox working on hdmi 3 @ 120hz 4k hdr with VRR disabled in Xbox menu and OLED TV set to hdmi 2.1 input manually. PS5 4k 60 HDR working on hdmi 1 with TV set to 2.1 manually, the 4k 120hz hdmi inputs don't work yet until Vizio issues out a new firmware ZEM7Y.
