## Long description

The StarTech.com DisplayPort Cable DP21-1M-DP40 is a 1 m DisplayPort 2.1 cable designed to connect UHD DisplayPort monitors to host computers or MST hubs, supporting up to 8K at 60Hz (with DSC) and high refresh rates such as 4K at 144Hz or 4K 120Hz on compatible devices. The cable is VESA Certified for DP 2.1 and is backward compatible with earlier DisplayPort versions. It includes UHBR10 capability, HDR10 support, HDCP 2.2 compliance and braided aluminum mylar shielding to minimize EMI for reliable audio/video output.
Advantages
This DisplayPort 2.1 DP40 cable facilitates high-bandwidth video and multi-channel audio suitable for demanding GPUs, 8K workstations and professional AV workflows. Durable construction includes a flexible TPE outer jacket tested for 600 bending cycles, robust strain reliefs and latching nickel-plated connectors rated for over 10,000 insertions. It supports Display Stream Compression (DSC) 1.2a, Multi-Stream Transport (MST) and up to 32 uncompressed audio channels for versatile configurations.
Suitable for
Connecting 8K/4K UHD monitors to desktop PCs, workstations or MST hubs
High-refresh-rate gaming setups and GPUs supporting G-Sync or FreeSync
Media production, content creation and professional AV installations
Daisy-chaining multiple monitors using MST

How to use
Connect one end of the DP21-1M-DP40 DisplayPort cable to the DisplayPort output on your host computer or GPU and the other end to the DisplayPort input on the monitor or MST hub. Ensure both source and display support the desired DP 2.1 features (for example UHBR10, DSC and HDCP 2.2) and select the appropriate resolution and refresh rate in your operating system or GPU control panel. For multi-monitor setups, configure MST/daisy-chain options on the source device as required.
Usage recommendations
Use this cable in environments where high bandwidth and reliable signal integrity are required. Route the cable around sharp edges and through cable management to avoid repeated extreme bends; the TPE jacket is rated for 600 bending cycles at ±60°. Verify compatibility of source and display for 8K/60Hz or high refresh rate modes and enable DSC or HDCP 2.2 if required by content or device settings.
