A report explains that PlayStation 5 consoles can display a working picture even when plugged into an HDMI port that doesn't support the console's full HDMI 2.1 capabilities, such as 4K at 120Hz. The guidance notes that TVs often have multiple HDMI ports with different specs, poorly labeled, and recommends checking a TV's exact model specifications and using an Ultra High Speed HDMI cable plugged directly into the display.
HDMI cables are now standardized into three official bandwidth tiers: Premium High Speed (18Gbps), Ultra High Speed (48Gbps) and the new Ultra96 (up to 96Gbps), per rules from the HDMI Licensing Administrator that ban using version numbers alone in marketing. Most 4K streaming only needs the 18Gbps tier, while 4K/120Hz gaming requires Ultra High Speed, and Ultra96 is reserved for extreme formats like uncompressed 4K/240Hz or 8K/60Hz. Buyers are advised to check the certification label and QR code on packaging rather than relying on price or brand name.
