80 Gbps线缆，适用于下一代显示设备：4K@240Hz、8K@85Hz（DSC）或16K@60Hz（DSC）。需要UHBR认证线缆。
Rated for 80 Gbps of UHBR 20 throughput, the DisplayPort 2.1 cable targets the highest-refresh and highest-resolution displays currently shipping. That bandwidth is enough for 4K at 240 Hz, 8K at 85 Hz with Display Stream Compression, or 16K at 60 Hz DSC. Reaching those numbers requires a cable carrying the VESA UHBR certification; uncertified DP cables silently fall back to slower link rates. Passive construction keeps the run short, with 2 meters a practical limit before signal integrity degrades. Its usual roles are 8K workstation displays and 4K 240 Hz gaming monitors driven from a DisplayPort 2.1 source. Retail pricing sits between $15 and $35.
