VESA Certified DisplayPort 2.1 Cable

This three-foot cable carries the DP80 badge, confirming 80 Gbps bandwidth under the DisplayPort 2.1 specification. It connects a DisplayPort 2.1 source to a DisplayPort 2.1 display for professional workstations and high-refresh gaming monitors. Builders needing longer runs or legacy DisplayPort 1.4 bandwidth should choose a different length or standard.

Sustained 80 Gbps Throughput

The UHBR20 link rate is maintained across the full 0.91 metre length without signal degradation. VESA certification validates eye-diagram compliance at the rated speed, so 10K 60Hz or 8K 60Hz uncompressed streams remain stable during extended sessions. The cable does not throttle or drop lanes under continuous load.

DP80 Bandwidth Ceiling

The 80 Gbps ceiling defines the practical limit: 16K 60Hz and 10K 144Hz require DSC 1.2a compression, while 8K 240Hz also depends on DSC. Uncompressed 4K 240Hz fits within the raw bandwidth. Displays or controllers that demand more than DP80 provides cannot be driven by this cable.

Questions about this item

Does the 3 ft DP80 cable generate any heat or add measurable power draw when driving an 8K 240 Hz DSC signal all day?

The cable is passive copper with no active electronics, so it adds no power draw and produces no measurable heat during continuous 80 Gbps operation.

What must my graphics card and monitor already provide for this DisplayPort 2.1 male-to-male cable to function?

Both ends need a native DisplayPort 2.1 (UHBR20) port; older DP 1.4 ports will fall back to their lower bandwidth limits.

If I keep my current DP 1.4 monitor and only upgrade the GPU to a DP 2.1 card, will this cable still work?

Yes — the cable is backward compatible and will negotiate the highest common link rate, so a DP 1.4 display runs at its native limit.
