Cable Matters 54Gbps USB C to DisplayPort 2.1 Cable DP54 3ft / 0.9m

- Next-Gen Video Output with DisplayPort 2.1: Experience ultra-high-definition visuals with this USB-C to DisplayPort 2.1 cable, supporting up to 8K@165Hz, 4K@480Hz, and 4K@240Hz on supported devices. This USB-C to DP 2.1 cable is ideal for high-refresh gaming, content creation, and pro workflows with smooth motion and sharp detail. - DP 2.1 DP54 (UHBR13.5) 54Gbps Bandwidth: Built for DisplayPort 2.1 DP54 / UHBR13.5 performance with up to 54Gbps video bandwidth for demanding 8K and high-refresh 4K displays. Backward compatible with DP40, DisplayPort 1.4, and DisplayPort 1.2 GPUs and monitors. - Unidirectional USB-C to DP Connection: This Thunderbolt 5 to DisplayPort cable is unidirectional?connect from a USB-C/USB4/Thunderbolt 5/4 port with DisplayPort Alt Mode to a DisplayPort monitor (not for USB-C monitor input or portable USB-C monitors). Supports MST for compatible daisy-chain setups and audio including 7.1 surround (when supported). - Host & Display Requirements: To reach 8K@165Hz or 4K@480Hz, the host must output DP 2.1 over USB-C (or DP 1.4 HBR3 + DSC), and the DisplayPort monitor must support the same mode. Actual resolution/refresh depends on GPU/DP link rate, DSC, OS limits, cable length, and display specs. - Durable, Secure Fit: Reinforced build for daily use with a locking DisplayPort latch for a stable connection. Press the release button before unplugging to protect your port and ensure a secure fit for workstations, docks, and desktop monitor setups.

Product description

Will this work with any USB-C port?

Will it work in reverse (DisplayPort source to USB-C monitor), or with a portable USB-C monitor?

Why can’t I get 8K@165Hz or 4K@480Hz?

I’m getting “No Signal” or flickering?what should I check first?

My DisplayPort connector won’t unplug easily?is something wrong?

Will this work with any USB-C port?

Only with USB-C/USB4/Thunderbolt 5/4 ports that support DisplayPort Alt Mode (video output). Charging-only or data-only USB-C ports will not output video.

Will it work in reverse (DisplayPort source to USB-C monitor), or with a portable USB-C monitor?

No. This cable is unidirectional (USB-C source → DisplayPort display only) and is not for USB-C monitor input or portable USB-C monitors.

Why can’t I get 8K@165Hz or 4K@480Hz?

These modes require both a host that outputs DP 2.1 over USB-C (DP54/UHBR13.5) and a DisplayPort monitor that supports the same mode. Otherwise it will fall back to a lower mode (often via DSC).

I’m getting “No Signal” or flickering?what should I check first?

Set the monitor to the correct DisplayPort input, update GPU drivers/firmware, reseat both ends, and avoid adapters/docks that may not support the required DP bandwidth.

My DisplayPort connector won’t unplug easily?is something wrong?

This cable has a locking DisplayPort latch. Press the release button before unplugging to protect the port.
