Backwards Compatibility
When using DP Alt Mode for video, available USB data bandwidth may be reduced depending on the number of DisplayPort lanes allocated.
Notes & Compatibility
Passive cables are limited to 0.8m at full 40Gbps speed. Active cables extend to 2-5m. Look for USB-IF certification and the USB-IF 240W power capability logo on packaging — this is one of the few standardized truth signals for cable power rating. Not all USB-C cables support USB4 — verify the cable rating before purchase.
