UGREEN USB-C to DisplayPort 1.4 Cable 1M – Black | CM556 25157

The UGREEN CM556 USB-C to DisplayPort 1.4 Cable (25157) is a high-performance unidirectional cable connecting any USB-C device with DisplayPort Alternate Mode — including Thunderbolt 3, Thunderbolt 4, and USB4 ports — directly to a DisplayPort monitor, TV, or projector at up to 8K@60Hz resolution with 32.4Gbps bandwidth. Featuring Dynamic HDR, HDCP 2.3, Display Stream Compression 1.2, Variable Refresh Rate, Auto Low Latency Mode, G-Sync and FreeSync compatibility, Multi-Stream Transport daisy chaining, and audio passthrough — the UGREEN 25157 covers every DisplayPort 1.4 capability in a single braided nylon, aluminium-connector cable. No adapters. No drivers. No signal conversion.

8K@60Hz — 32.4GBPS DISPLAYPORT 1.4 BANDWIDTH

The UGREEN 25157 carries the full 32.4Gbps bandwidth of the DisplayPort 1.4 standard — the maximum throughput required to drive an 8K (7680×4320) display at 60Hz over a single cable. The resolution support hierarchy covers every modern monitor category:

- 8K (7680×4320) @ 60Hz — for 8K professional reference monitors

- 4K (3840×2160) @ 240Hz — for ultra-high-refresh 4K gaming monitors

- 2K (2560×1440) @ 240Hz — for QHD competitive gaming monitors

- 1080P @ 240Hz — for FHD high-refresh gaming displays

The same cable serves every scenario — from professional 8K colour grading to competitive FHD gaming at maximum refresh rate — without replacing the cable as monitors are upgraded.

DYNAMIC HDR — SCENE-BY-SCENE LUMINANCE OPTIMISATION

Dynamic HDR (HDR10+/Dolby Vision compatible) optimises brightness, contrast, and colour on a scene-by-scene or frame-by-frame basis — every shot in a film, every scene in a game, and every frame in a video stream is tone-mapped individually rather than applying a single static HDR profile across all content. The result: brighter highlights, deeper shadows, and more accurate colour rendering in HDR-graded content than static HDR metadata provides.

VARIABLE REFRESH RATE (VRR) + AUTO LOW LATENCY MODE (ALLM)

Variable Refresh Rate synchronises the monitor's refresh rate to the GPU's output frame rate — eliminating screen tearing and the stutter of V-Sync buffering without the input lag increase that V-Sync introduces. ALLM (Auto Low Latency Mode) automatically switches the connected display into its lowest-latency operating mode when gaming content is detected — reducing display processing delay for faster, more responsive input response. Both features operate automatically through the cable without software configuration.

G-SYNC AND FREESYNC COMPATIBLE

G-Sync (NVIDIA) and FreeSync (AMD) adaptive sync certifications are supported through the USB-C to DisplayPort cable — tear-free, stutter-free adaptive sync gaming is available on G-Sync Compatible and FreeSync/FreeSync Premium monitors from both GPU manufacturers via this cable.

DISPLAY STREAM COMPRESSION 1.2 (DSC) — VISUALLY LOSSLESS HIGH RESOLUTION

DSC 1.2 is the compression technology that enables 8K@60Hz and 4K@240Hz transmission within the 32.4Gbps bandwidth envelope of DisplayPort 1.4. DSC is defined as visually lossless — the compression algorithm operates below the threshold of human visual perception, delivering output that is functionally indistinguishable from uncompressed transmission at standard viewing distances. Without DSC, 8K@60Hz would require 40Gbps+ bandwidth — DSC makes it possible within DP 1.4's 32.4Gbps ceiling.

HDCP 2.3 — CONTENT PROTECTION

HDCP 2.3 copy protection compliance enables playback of DRM-protected streaming content including Netflix 4K, Disney+ 4K, and other premium streaming services through the connected display — without HDCP compliance, DRM-protected content is blocked or reduced to lower resolutions.

MST MULTI-STREAM TRANSPORT — DAISY CHAIN MULTIPLE MONITORS

Multi-Stream Transport enables MST daisy chaining — connecting multiple DisplayPort monitors in series from a single USB-C source for extended multi-monitor desktop configurations. The USB-C host → UGREEN 25157 → Monitor 1 (MST out) → Monitor 2 chain creates a multi-monitor setup without additional cables from the source device.

FIVE DISPLAY MODES SUPPORTED

- MST Daisy Chain: multi-monitor chaining from one USB-C port

- Samsung DeX: desktop-mode display for compatible Samsung Galaxy devices

- MacBook Clamshell: connect a MacBook to a DisplayPort monitor in closed-lid desktop mode

- Mirror mode: duplicate the source display on the external monitor

- Extend mode: extend the desktop across the connected monitor for additional workspace

THUNDERBOLT 3, THUNDERBOLT 4, AND USB4 COMPATIBLE

The USB-C end of the 25157 is compatible with all USB-C ports that support DisplayPort Alternate Mode:

- Thunderbolt 4 (40Gbps): full 8K@60Hz bandwidth available

- Thunderbolt 3 (40Gbps): full 8K@60Hz bandwidth available

- USB4 (40Gbps): full 8K@60Hz bandwidth available

- USB 3.2 Gen 2 with DP Alt Mode: up to 4K@60Hz (bandwidth dependent)

- USB-C with DP Alt Mode: up to maximum DP Alt Mode bandwidth available on that port

The cable does not work in reverse — it transmits from USB-C to DisplayPort only. DisplayPort source to USB-C display is not supported.

BRAIDED NYLON + ALUMINIUM CONNECTORS — DURABLE CONSTRUCTION

The braided nylon cable exterior provides abrasion resistance, strain relief at the bend point near connectors, and tangle resistance during daily connection and disconnection. Aluminium alloy connector housings protect the internal pin contacts from mechanical stress and provide a premium tactile quality at both ends. Gold-plated connector pins resist oxidation and maintain consistent signal contact quality across thousands of connection cycles.

PLUG AND PLAY — NO DRIVERS, NO ADAPTERS

The UGREEN 25157 requires no driver installation on Windows, macOS, or Linux — plug into the USB-C port and the DisplayPort monitor and video output begins immediately. No signal converters, adapters, or active electronics are in the cable path — direct passive DisplayPort Alternate Mode transmission from USB-C end to DisplayPort end.
