ULT-unite HDMI to Type-C Adapter User Manual

1. Product Overview

Thank you for choosing the ULT-unite HDMI to Type-C adapter. This product is a high-performance audio/video conversion adapter designed to transmit standard HDMI source signals to display devices that use a Type-C video input interface. It features an active built-in chip for conversion, supports up to 4K Ultra HD (3840x2160) @ 60Hz high-definition resolution, and is equipped with an independent Type-C power delivery port to ensure stable and smooth transmission.

Important Note: This product is unidirectional. The signal direction is ONLY HDMI to Type-C. It cannot be used to convert Type-C to HDMI.

Key Features:

• Ultra High Definition: Supports up to 4K@60Hz output, backward compatible with 2K, 1080P, and other resolutions.
• Broad Compatibility: Compatible with Type-C displays and AR glasses supporting DP Alt Mode.
• Independent Power Delivery: Type-C power input (5V/1A or higher) provides additional power to ensure stable operation with larger displays and demanding devices.
• Durable Construction: Aluminum alloy shell for heat dissipation, ABS engineering plastic front/rear covers. Ports feature nickel-plated shells and gold-plated terminals for oxidation resistance and durability.
• Plug and Play: No drivers required. Automatically recognizes and outputs the display signal after connection.

3. Setup and Connection

The ULT-unite HDMI to Type-C adapter offers simple plug-and-play functionality. Follow these steps for proper connection:

General Connection Method:

1. Connect the Source: Use a standard HDMI cable. Connect one end to your video source device (e.g., laptop, game console) and the other end to the adapter's HDMI Female port.
2. Connect Power (IMPORTANT!): Use another USB Type-C cable. Connect one end to a 5V/1A or higher power USB charger (not included) and the other end to the adapter's Power Input port. Connecting independent power is strongly recommended for stable operation, especially with larger displays or demanding devices.
3. Connect the Display Device: Use a full-featured Type-C cable. Connect one end to the adapter's Type-C Output port and the other end to your Type-C display device (e.g., portable monitor, AR glasses).
4. Power On: Power on all devices. The display device should automatically recognize and display the source image.

Instructions for AR Glasses (XREAL, Rokid, RayNeo, etc.):

Standard Connection Steps:

1. Connect the HDMI source to the adapter.
2. Connect the power cable to the adapter's power Input port.
3. Plug the AR glasses Type-C video cable directly into the adapter's Type-C Output port.
4. Turn on the source device and the AR glasses.

Special Instructions for XREAL Glasses:

When connected to Nintendo Switch:

• You MUST use the original Nintendo Switch charger to power the dock.
• The controller must be removed from the Switch to operate the game.

When connected to a PC, Laptop, TV Box, PS4/PS5:

• The power cable must be connected to a wall charger, not to the USB-A port of the source device or console, as most USB-A ports are underpowered.

Instructions for Portable Monitors:

Connection Steps MUST follow this order:

1. First: Connect the power cable to the adapter's power input port and to a wall charger. (This initial power-up is crucial).
2. Then: Connect the HDMI source to the adapter.
3. Finally: Connect the portable monitor to the adapter's Type-C Output port using its video cable.
4. Turn on all devices.

4. Operating Instructions

The ULT-unite HDMI to Type-C adapter is designed for ease of use with its plug-and-play functionality. Once all connections are made as described in the "Setup and Connection" section, the adapter will automatically detect the input signal and output it to your Type-C display device.

Ensure your source device (e.g., laptop, game console) is powered on and configured to output video via its HDMI port. Your Type-C display device should also be powered on and set to receive input from its Type-C port.

5. Maintenance

• Do not connect in reverse. This product cannot convert Type-C signals to HDMI signals.
• Avoid bending or pulling the cables forcefully during use.
• Do not use the product in high temperature, humid, or dusty environments.
• Clean with a dry, soft cloth. Do not use chemical solvents.
• If not used for an extended period, disconnect all cables and store in a dry place.

6. Troubleshooting

Q1: No Picture, "No Signal" Displayed

1. Check Power: This is the most common cause. Ensure you have connected independent power to the adapter using a 5V/1A or better charger.
2. Check Connection Sequence: Follow the correct order, especially for portable monitors (see "Instructions for Portable Monitors" in Section 3).
3. Check Cables: Confirm all cables are working and are high-quality (especially the Type-C video cable).
4. Check the Source: Ensure your video source device is powered on and outputting a signal.
5. Check Resolution: Try lowering the output resolution on the source device to 1080P@60Hz first.
6. Try re-plugging all cables firmly.

Q2: Picture Flickers, Blacks Out, or Has Color Abnormalities

1. Insufficient Power: Try using a higher power charger (e.g., 5V/2.4A or 3A).
2. Cable Quality: Replace HDMI or Type-C cables with higher quality, certified ones.

Q3: Picture is Displayed but There is No Sound

Important: This converter transmits VIDEO signal only. Audio routing must be managed separately.

General Solutions:

1. For devices with built-in speakers: Set the audio output on your source device to its own speakers or audio jack.
2. Connect headphones or speakers directly to the audio output of your source device.

For XREAL Glasses specifically, follow the "Audio Setup" steps:

XREAL Audio Troubleshooting:

1. Ensure XREAL glasses firmware is updated to the latest version via the XREAL App.
2. After connecting, press and hold the brightness button (ringing once), then press and hold brightness button (ringing twice), wait for 1 second, and the audio and video will be displayed at the same time. (Note: This operation is required after each re-plugging).
3. The audio output on the HDMI output device needs to be switched to headphone output or other peripherals.

8. User Tips

• Cable Quality Matters: Always use high-quality, certified HDMI and Type-C cables to ensure stable video transmission and prevent flickering or signal loss. Some users reported issues were resolved by using better cables that support DP Alt Mode.
• Adequate Power Supply: For optimal performance, especially with larger displays or power-hungry devices like portable monitors, ensure you provide sufficient power (5V/1A or higher) to the adapter's power input port using a dedicated wall charger. A standard phone charger often works well.
• AR Glasses Compatibility: This adapter is confirmed to work seamlessly with popular AR glasses such as RayNeo Air 3 Pro/4 Pro, XREAL Air, and Rokid Max 2, often without additional configuration.
• Nintendo Switch Specifics: When connecting to a Nintendo Switch, use the original Switch charger to power the dock for stable operation.
• Audio Management: Remember that this adapter only transmits video. For audio, you will need to manage it separately through your source device's audio output (e.g., built-in speakers, headphones, or external speakers connected to the source).
• Wacom One Compatibility: The adapter can replace Wacom Link Plus for devices like Wacom One 12, supporting screen, pen touch, and pressure sensitivity when sufficient power is provided.
• Fire TV Stick Integration: The adapter works well for converting Fire TV Stick output to USB-C for display on compatible devices.
