4K@60Hz Ultra HD

The UGREEN 50571 supports detailed 4K UHD video at up to 60Hz when connected to compatible equipment.

*The final resolution and refresh rate depend on the source device, USB-C video capabilities, HDMI display, operating system, graphics hardware, content, and configuration.

USB-C DisplayPort Alt Mode Requirement

The USB-C port on the source device must support video output through one of the following:

• DisplayPort Alternate Mode
• Thunderbolt 3
• Thunderbolt 4
• Compatible USB4 video output

A charging-only or data-only USB-C port will not work with this cable. The USB-C connector shape by itself does not confirm video capability.

Check the device specifications for DP Alt Mode, Thunderbolt, or external-display support before purchasing.

Active USB-C-to-HDMI Conversion

The cable contains an active chipset that converts the DisplayPort video signal provided through USB-C into an HDMI signal.

Connection path:

USB-C computer, tablet, or phone → UGREEN 50571 → HDMI display

No separate adapter, software driver, or external power source is normally required.

Unidirectional Connection

The cable operates only in the following direction:

• USB-C connects to the source.
• HDMI connects to the display.

It cannot be used to:

• Connect an HDMI computer to a USB-C monitor
• Connect a game console to a USB-C display
• Convert HDMI output into USB-C video
• Connect an HDMI source to a Thunderbolt monitor

HDR Support

The UGREEN 50571 supports compatible HDR signals, providing enhanced:

• Contrast
• Brightness
• Color reproduction
• Highlight detail
• Shadow detail
• Overall image depth

HDR requires compatible source hardware, content, operating-system settings, HDMI input, and display.

3D Video Support

The cable can transmit compatible 3D video formats between a suitable USB-C source and an HDMI 3D display.

A compatible source, appropriate content, and a 3D-capable television or projector are required.

HDCP 2.2 and HDCP 1.4

The UGREEN 50571 supports HDCP 2.2 and HDCP 1.4 for compatible protected digital content.

This can include supported content from services and applications such as:

• Netflix
• Amazon Prime Video
• YouTube
• iTunes or Apple TV applications
• Other protected streaming platforms

HDCP must be supported throughout the complete connection. Service policies, device restrictions, and operating-system limitations can still affect playback.

Digital Audio and Video

The cable carries compatible HDMI video and digital audio simultaneously.

Audio can be transmitted to:

• Televisions
• HDMI monitors with speakers
• Projectors with speakers
• AV receivers
• Sound systems connected through the display

The available audio format depends on the source, content, receiving equipment, and system settings.

Mirror and Extended Display Modes

The UGREEN 50571 supports common external-display configurations.

Mirror mode

Shows the same image on the source device and HDMI display.

Extended mode

Uses the HDMI monitor as additional desktop space.

Clamshell mode

Compatible MacBook models can operate with their lid closed when the required external power, keyboard, mouse, and display conditions are met.

Samsung DeX

Compatible Galaxy phones and tablets can provide a desktop-style interface on the connected HDMI display.

Huawei PC mode

Supported Huawei devices can provide their compatible desktop interface on an external display.

Durable Braided Construction

The cable features:

• Tinned-copper internal conductors
• Triple-layer signal shielding
• Gold-plated connector contacts
• Aluminum-alloy connector housings
• Reinforced connector joints
• Flexible nylon-braided outer jacket

The aluminum housings assist with heat dissipation, while the braided exterior provides protection against everyday bending and abrasion.

What This Cable Does Not Do

• It does not charge the connected device.
• It does not provide ordinary USB data transfer.
• It does not work from HDMI to USB-C.
• It does not split one source across several displays.
• It does not switch between multiple sources.
• It does not extract audio to optical or 3.5mm outputs.
• It does not add video output to an unsupported USB-C port.
• It does not provide 4K@120Hz or 8K output.
• It does not provide HDMI 2.1 gaming features such as VRR or ALLM.

Installation

1. Connect the USB-C plug to the source device.
2. Connect the HDMI plug to the television, monitor, projector, or receiver.
3. Select the correct HDMI input on the display.
4. Open the source device’s display settings.
5. Select mirror or extended mode.
6. Choose a supported resolution and refresh rate.
7. Enable HDR if required.

For maximum stability, connect the cable directly. Additional docks, couplers, extension cables, switches, and adapters can prevent 4K@60Hz from working correctly.

Important Notes

To obtain 4K@60Hz, the complete connection must support it:

Compatible USB-C video source → UGREEN 50571 → compatible HDMI display

If 4K@60Hz is unavailable:

• Confirm that the USB-C port supports DisplayPort Alt Mode.
• Update the source device and graphics driver.
• Connect directly without a dock or hub.
• Enable Enhanced HDMI, UHD Color, Deep Color, or the equivalent display setting.
• Select an HDMI input that supports 4K@60Hz.
• Test a lower resolution or refresh rate.
• Check the source device’s documented external-display limit.
