Ugreen usb 3.0 to hdmi+vga converter-UG-20518
The Ugreen UG-20518 transforms a single USB 3.0 port into dual display outputs. This converter delivers simultaneous HDMI and VGA connectivity through an integrated 15cm cable. The aluminum alloy housing provides structural durability while maintaining a compact, portable design.
This adapter leverages USB 3.0 bandwidth to transmit video signals to external displays. The device operates through DisplayLink chipset technology, enabling additional screen functionality without occupying dedicated graphics ports.
Dual Output Architecture
Simultaneous Display Connection
The UG-20518 features two output interfaces functioning concurrently. The HDMI port supports digital video transmission with audio capability, while the VGA port provides analog video output. Both interfaces deliver 1920×1080 resolution at 60Hz refresh rate.
When both outputs operate simultaneously, the converter functions in clone mode. This configuration mirrors identical content across both connected displays. For extended desktop functionality, users should activate only one output interface at a time.
Resolution and Refresh Rate Performance
Both output ports support Full HD 1080p video at 60Hz. The HDMI interface transmits digital signals with integrated audio channels. The VGA port handles analog video signals without audio transmission. Cable length affects signal integrity, with optimal performance maintained up to 15 meters.
The 60Hz refresh rate ensures smooth motion rendering for video playback and presentation content. This specification suits standard office applications, multimedia consumption, and professional presentation scenarios.
USB 3.0 Integration
The UG-20518 requires USB 3.0 port connectivity for proper operation. The USB 3.0 standard provides 5Gbps theoretical bandwidth, enabling sufficient data throughput for dual 1080p video streams. USB 2.0 ports lack adequate bandwidth and will not support this converter.
The integrated 15cm cable connects directly to host devices without requiring separate cables. Bus-powered operation eliminates external power adapter requirements. The converter draws power exclusively from the USB 3.0 port.
Construction and Physical Design
Aluminum Alloy Housing
The UG-20518 chassis consists of aluminum alloy material. This metal construction provides thermal conductivity, dissipating heat generated during video processing. The material resists oxidation and corrosion, maintaining structural integrity across extended operating periods.
The compact form factor measures approximately 8.5cm × 2cm × 14cm in package dimensions. The adapter itself maintains minimal desk footprint while providing dual output capability. The unit weighs 150 grams including packaging.
Integrated Cable Configuration
The converter features a permanently attached USB-A cable measuring 15cm in length. This fixed cable design reduces connection points and potential signal degradation. The flexible cable construction accommodates various workspace configurations without excessive stress on connectors.
