UGREEN CM151 50291 USB-to-HDMI Digital AV Adapter 1.5M – 1080p@60Hz Mobile Screen Mirroring for iOS, Android, Windows & macOS – Gray

Description

The UGREEN CM151 50291 is a software-assisted USB-to-HDMI Digital AV adapter designed to mirror video from a compatible smartphone, tablet, or computer onto an HDMI television, monitor, or projector.

Unlike a conventional USB-C-to-HDMI cable, it uses a USB-A female input for the source device’s USB data cable. A separate USB-A male lead supplies power, while the integrated HDMI male connector connects to the display.

It supports video resolutions up to Full HD 1920 × 1080 at 60Hz and can work with compatible USB-C, Micro-USB, or Lightning devices through their appropriate USB data cables.

Full HD 1080p Output

The UGREEN 50291 supports video output up to Full HD 1920 × 1080 at 60Hz.

*The actual output depends on the source device, operating system, application, USB data connection, and receiving display.

How the Adapter Works

The adapter uses three separate connections:

1. USB-A female input: Connects to the phone, tablet, or computer using its compatible USB data cable.
2. HDMI male output: Connects directly to the television, monitor, or projector.
3. USB-A male power lead: Connects to a stable 5V USB power source.

Connection example:

Smartphone → phone’s USB data cable → UGREEN 50291 → HDMI display

The adapter’s separate USB-A power lead must also be connected during operation.

Software-Assisted Screen Mirroring

The UGREEN 50291 uses a software-assisted casting system rather than native USB-C DisplayPort Alt Mode.

EZCast software is required for supported Android devices and may also be required for Windows or macOS systems. The user may need to grant:

• Screen-recording permission
• USB device access
• Screen-sharing permission
• Application overlay permission
• Local-network access, depending on the software version

Compatibility depends on continued support from the operating system and EZCast application.

USB-C, Micro-USB and Lightning Support

The USB-A female input can accept the source device’s appropriate USB data cable, including:

• USB-A to USB-C
• USB-A to Micro-USB
• USB-A to Lightning

These cables are normally supplied separately.

This design can work with certain devices that do not provide native DisplayPort Alt Mode, but the device and operating system must be supported by the EZCast software.

USB 2.0 Data Connection

The adapter uses a USB 2.0 connection with a listed maximum data-transfer rate up to 480Mbps.

This bandwidth is used by the casting system to send the mirrored video to the adapter. It is not comparable to the bandwidth of a direct HDMI 2.0 or USB-C DisplayPort connection.

Because the picture is processed through USB and software, some delay or compression may be visible.

Video-Only Output

Exact UGREEN documentation for SKU 50291 states that the adapter transmits video only and does not provide HDMI audio.

For sound, use a separate audio connection such as:

• The phone or tablet’s built-in speaker
• Bluetooth headphones
• A Bluetooth speaker
• A compatible wired audio output
• The computer’s separate audio output

Do not purchase this model if HDMI audio transmission is required.

Suitable Uses

The adapter is suitable for:

• Displaying photographs on a television
• Basic video presentations
• Classroom demonstrations
• Showing documents on a projector
• Mirroring mobile applications
• Displaying web pages on a larger screen
• Basic office presentations
• Viewing locally stored media where the application permits mirroring

Because software processing can introduce latency, it is not ideal for competitive gaming or other delay-sensitive applications.

Compatibility

Compatible device categories can include:

• iPhones using an appropriate Lightning cable
• iPads
• Android smartphones
• Android tablets
• Samsung devices
• Huawei devices
• Xiaomi devices supported by the application
• HTC devices
• USB-C mobile devices
• Micro-USB mobile devices
• Windows computers
• macOS computers

Listed minimum operating-system versions include:

• iOS 9.0 or later
• Android 5.0 or later

Modern operating-system compatibility should be checked before purchase because application permissions and screen-mirroring policies can change.

Display Compatibility

The integrated HDMI male connector can connect to compatible:

• HDTVs
• Full HD televisions
• HDMI monitors
• Projectors
• Presentation displays
• HDMI-equipped receivers used for video routing

The receiving display must have a standard HDMI Type-A input.

Power Requirements

The USB-A male power connector requires a stable 5V USB power source within the product’s stated tolerance of 5V ±5%.

Possible power sources include:

• USB wall charger
• Powered USB hub
• Television USB port with sufficient output
• Computer USB port

A USB wall charger is not necessarily included.

The power cable operates the adapter. It is not intended to provide high-speed or fast charging to the connected phone or tablet.

Specifications

Installation

1. Connect the adapter’s HDMI plug to the television, monitor, or projector.
2. Connect the USB-A male power lead to a stable 5V USB power source.
3. Connect the phone, tablet, or computer to the USB-A female port using a compatible data cable.
4. Select the correct HDMI input on the display.
5. Install or open the required EZCast application.
6. Grant any requested USB, screen-recording, or casting permissions.
7. Follow the application instructions to begin screen mirroring.

If the display remains blank, reconnect the power lead and confirm that the source cable supports data transfer rather than charging only.

Important Streaming Limitations

Some subscription video services and other protected applications may block software-based screen mirroring because of DRM or HDCP restrictions.

Possible results include:

• A black video window
• Audio or interface elements without the video
• An application warning
• Reduced playback resolution
• Mirroring being disabled entirely

Compatibility with Netflix, Amazon Prime Video, Disney+, banking applications, or other protected services is not guaranteed.

Troubleshooting

If no image appears:

• Confirm that the USB-A power lead is connected.
• Use a stable 5V USB power source.
• Confirm that the source cable supports data transfer.
