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 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.

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).

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.

Comparison Products 54G USB C to DP Cable 40G USB C to DP Cable USB C to HDMI 2.1 Cable USB C to DP 2.1 USB C to HDMI 2.1 Adapter DisplayPort 2.1 Cable Long 8K HDMI Cable Review: Great cord…bought 2 of them! - Great cable, definitely worth the money. Backwards compatibility is nice. Love the braided cord, makes it feel more durable. Speed and picture quality is great also. My only complaint is the button on the DP end can be hard to keep pushed in when plugging into your monitors. Especially if your monitors port is on the bottom and you have to keep the cord flat against the monitor to plug it in. Review: Does the job - Works as advertised. Helped me connect my M5 mac to an older Dell 38" ultrawide where USB video/power negotioation is spotty at best. Just using office apps at native resolution so I can't speak to high bandwidth applications or refresh rates. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0G7X31GWJ | | Best Sellers Rank | #1,323 in USB Cables | | Brand | Cable Matters | | Brand Name | Cable Matters | | Cable Type | USB-C to DisplayPort | | Color | Black | | Compatible Devices | Laptop | | Connector Type | USB Type C | | Customer Reviews | 4.4 out of 5 stars 79 Reviews | | Data Transfer Rate | 54 Gigabits Per Second | | Frequency | 54000000000 Hz | | Indoor Outdoor Usage | Indoor | | Manufacturer | Cable Matters Premium USB-C to DisplayPort 2.1 Cable - 6ft / 1.8m | | Model | 201456-BLK-6 | | Number of Pins | 44 | | Other Special Features of the Product | DP2.1 | | Part Number | 201456-BLK-6 | | Recommended Uses For Product | Gaming, Content Creation, Pro Workflows | | Special Feature | DP2.1 | | UPC | 682017357003 | | Unit Count | 6.0 Feet | ## Images ![Cable Matters 54Gbps Unidirectional USB C to DisplayPort 2.1 Cable - 6ft / 1.8m, Supports DP54, 8K@165Hz / 4K@480Hz (Thunderbolt 5 to DisplayPort Cable) - Not for Portable USB-C Monitor - Image 1](https://m.media-amazon.com/images/I/71NSpE-lUpL.jpg) ![Cable Matters 54Gbps Unidirectional USB C to DisplayPort 2.1 Cable - 6ft / 1.8m, Supports DP54, 8K@165Hz / 4K@480Hz (Thunderbolt 5 to DisplayPort Cable) - Not for Portable USB-C Monitor - Image 2](https://m.media-amazon.com/images/I/81DujhW29wL.jpg) ![Cable Matters 54Gbps Unidirectional USB C to DisplayPort 2.1 Cable - 6ft / 1.8m, Supports DP54, 8K@165Hz / 4K@480Hz (Thunderbolt 5 to DisplayPort Cable) - Not for Portable USB-C Monitor - Image 3](https://m.media-amazon.com/images/I/81pKEbI4iiL.jpg) ![Cable Matters 54Gbps Unidirectional USB C to DisplayPort 2.1 Cable - 6ft / 1.8m, Supports DP54, 8K@165Hz / 4K@480Hz (Thunderbolt 5 to DisplayPort Cable) - Not for Portable USB-C Monitor - Image 4](https://m.media-amazon.com/images/I/81fnwADlbeL.jpg) ![Cable Matters 54Gbps Unidirectional USB C to DisplayPort 2.1 Cable - 6ft / 1.8m, Supports DP54, 8K@165Hz / 4K@480Hz (Thunderbolt 5 to DisplayPort Cable) - Not for Portable USB-C Monitor - Image 5](https://m.media-amazon.com/images/I/71ng3i2Xr7L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this work with any USB-C port?** A: Only with USB-C/USB4/Thunderbolt 5/4 ports that support DisplayPort Alt Mode (video output).
