USB-C to DisplayPort 1.4 cable 3.3ft

This cable connects a USB-C source that supports DP Alt Mode to a DisplayPort monitor. It handles 32.4 Gbps bandwidth for 8K at 60 Hz, 4K at 144 Hz and 2K at 240 Hz. The link is suited for creative professionals and high-refresh-rate gamers who need a direct, single-cable connection without adapters.

Sustained high-resolution throughput

The HBR3 link maintains 32.4 Gbps across the 3.3 ft length with DSC 1.2 compression for visually lossless 8K or high-refresh 4K and 2K signals. Dynamic HDR and 32-bit audio pass through without flicker or signal drop during extended sessions. Backwards compatibility with DisplayPort 1.3, 1.2 and 1.1 ensures stable operation on older displays.

Upgrade path and limits

Replaces older USB-C to DP cables limited to HBR2 bandwidth or 4K at 60 Hz. The jump is worthwhile when the host and monitor both support DP 1.4 HBR3 and DSC for 8K60, 4K144 or 2K240. Not for users whose source lacks DP Alt Mode, who need Thunderbolt tunnelling for data, or who require longer runs beyond 3.3 ft.

Questions about this item

How much heat or power does the cable generate when running an 8K 60 Hz signal all day?

The cable is passive and draws no external power; it simply carries the 32.4 Gbps DisplayPort 1.4 stream without active circuitry, so it stays at room temperature during continuous use.

My laptop has a USB-C port — how do I know it will drive this cable?

The host must support USB Type-C DP Alt Mode; the cable works with Thunderbolt 4 or 3 ports and any USB-C port that advertises DisplayPort alternate mode.

Will this cable work with my older DisplayPort 1.2 monitor at 4K 60 Hz?

Yes, the cable is backwards compatible with DisplayPort 1.3, 1.2 and 1.1, so a 4K 60 Hz signal over a DP 1.2 display will pass through without issue.
