Ugreen UG- 30841 USB Type C to HDMI Cable Male to Male ABS Case 1.5m (White)

The Ugreen UG-30841 represents a specialized display connectivity solution engineered for USB-C to HDMI video transmission. This 1.5-meter cable features USB Type-C male to HDMI male architecture with integrated PS176 chipset technology, delivering 4K Ultra HD resolution support at 60Hz refresh rates. Built with 24K gold-plated connectors, aluminum case construction, and nylon braided jacket, the cable implements DisplayPort Alternate Mode protocol for direct video and audio transmission between USB-C devices and HDMI displays.

4K Ultra HD Video Resolution Support

The UG-30841 cable delivers video output up to 4K resolution at 60Hz (3840×2160 pixels). This specification provides four times the pixel density of Full HD 1080p displays, ensuring exceptional image clarity for content creation, gaming, and media consumption. Additionally, the cable supports 2K resolution at 30Hz for displays with lower refresh rate requirements.

Furthermore, the Ugreen 30841 maintains backward compatibility with lower resolution standards including 1080p Full HD, 720p HD, and standard definition outputs. This versatility ensures proper functionality across diverse display equipment from legacy monitors to modern 4K televisions and professional-grade projectors.

Advanced PS176 Chipset Integration

This cable incorporates a built-in PS176 chipset that performs active signal conversion between DisplayPort Alternate Mode and HDMI protocols. The PS176 processor ensures stable video transmission by managing signal timing, voltage regulation, and protocol translation functions. This active conversion eliminates common connectivity issues including screen flickering, signal dropout, and color reproduction errors.

Moreover, the Ugreen UG-30841 integrates EDID (Extended Display Identification Data) functionality that enables automatic resolution detection and optimal display configuration. The chipset supports HPD (Hot Plug Detection) for automatic device recognition when connecting or disconnecting displays, plus automatic wake-up functionality that restores display output when devices exit sleep modes.

Premium Gold-Plated Connector Construction

The 30841 model features 24K gold-plated contact surfaces on both USB-C and HDMI connectors. Gold plating provides superior electrical conductivity compared to standard tin or nickel plating while offering exceptional corrosion resistance. This specification maintains optimal signal transmission integrity across extended usage periods and prevents oxidation-related connection degradation.

Additionally, the cable incorporates metal plug housings with precision-engineered connector pins that ensure consistent contact pressure across all signal pathways. The gold plating extends connector lifespan through repeated insertion cycles while maintaining low contact resistance for reliable high-frequency signal transmission required by 4K video content.

Multi-Layer Shielding Architecture

The Ugreen UG-30841 features triple-layer shielding construction that protects against electromagnetic interference. This architecture includes aluminum foil shielding layers combined with braided metal shielding, creating comprehensive EMI protection. The multi-layer design prevents external radio frequency interference from degrading video signal quality during transmission.

Furthermore, multiple interior shielding layers isolate individual conductor pathways, preventing crosstalk between video data channels, audio signals, and control lines. This construction maintains signal integrity across the full 1.5-meter cable length, ensuring stable 4K video transmission without artifacts, pixelation, or audio synchronization issues.

Durable Nylon Braided Jacket Design

The 30841 cable features a nylon braided outer jacket that provides mechanical protection superior to standard PVC cable construction. Nylon braiding offers resistance against abrasion, cutting, and fraying damage from repeated bending cycles. The braided design maintains flexibility while preventing cable kinking that can damage internal conductors.

Moreover, the Ugreen 30841 incorporates an aluminum case housing at connector junctions that accelerates heat dissipation during operation. Aluminum construction provides structural rigidity that prevents connector deformation while offering rust resistance and EMI shielding properties. The white color finish maintains aesthetic appeal across diverse installation environments.

DisplayPort Alternate Mode Protocol

The UG-30841 utilizes DisplayPort Alternate Mode technology that repurposes USB-C connector pins for direct video signal transmission. This protocol enables USB-C devices to output video signals without requiring separate display controller hardware. The cable supports DisplayPort 1.2 specification bandwidth sufficient for 4K@60Hz video transmission.

Additionally, the cable implements proper USB-C configuration channel communication that negotiates DisplayPort Alternate Mode activation with compatible source devices. This ensures proper protocol handshaking and prevents incompatibility issues with devices that don’t support video output through USB-C ports.

Dual Display Mode Functionality

The Ugreen 30841 supports both mirror mode and extended display mode configurations. Mirror mode duplicates the source device display content onto external monitors, ideal for presentations and media viewing. Extended mode treats the HDMI display as separate screen space, enabling productivity workflows across multiple monitors with independent content on each display.

Furthermore, the cable supports Samsung DEX mode for Samsung Galaxy devices and Huawei PC Mode for compatible Huawei smartphones. These modes transform mobile devices into desktop computing experiences when connected to external displays, keyboards, and mice, enabling laptop-style productivity from smartphone hardware.
