4. Setup Instructions

1. Connect Input Source: Connect your HDMI source device (e.g., Blu-ray player, game console, PC) to the HDMI IN port on the splitter using an HDMI cable.
2. Connect Output Displays: Connect your two HDMI display devices (e.g., TV, monitor, projector) to the HDMI OUT 1 and HDMI OUT 2 ports on the splitter using HDMI cables.
3. Connect Power: Connect the provided Micro USB power cable to the splitter's power input port. For stable operation, connect the other end of the USB cable to a 5V1A power adapter (sold separately) and plug it into a power outlet.
4. Power On: Power on your HDMI source device and both display devices. The splitter's LED indicators will show its operating status (Power: solid red, Signal connection: solid green).

This image illustrates a setup where a laptop is connected to the HDMI splitter, which then duplicates the video signal to two external monitors, creating a mirrored display for a gaming or workstation environment.

5. Operating Instructions

The avedio links HDMI Splitter operates on a plug-and-play basis. Once connected as described in the setup section, it will automatically duplicate the input signal to both connected displays.

EDID Management

The splitter features EDID management to optimize resolution settings for your displays. There are two modes:

• Auto Mode: In this mode, the splitter automatically detects the common highest resolution supported by both connected displays and outputs the signal at that resolution. This is the default and recommended mode for most setups.
• Copy Mode: In this mode, the splitter copies the EDID information from the display connected to HDMI OUT 1. It then outputs the signal at the resolution supported by the HDMI OUT 1 display, unifying the output resolution for both displays based on OUT 1's capabilities. This mode is useful when you have displays with different maximum resolutions and want to prioritize the resolution of a specific display (connected to OUT 1).

To switch between EDID modes, refer to the physical switch or button on the device, if available, or consult the included instruction manual for specific controls.

This image demonstrates how the HDMI splitter can be used to share the same video content across different rooms, such as a living room and a bedroom. An inset graphic explains the EDID Auto and Copy modes for resolution management.

7. Important Usage Notes

Please be aware of the following limitations and considerations:

• This HDMI splitter is designed exclusively for "duplicate/mirror display". It does not support extended mode (displaying different content on two screens).
• It does not function as an HDMI switch (2 inputs 1 output).
• It does not function as an HDMI audio extractor (for connecting to soundbars or separate audio systems).
• ARC/eARC (Audio Return Channel/enhanced Audio Return Channel) are not supported.

This image clarifies that the HDMI splitter does not support extended display mode, where two screens show different content, nor does it support direct connection to audio devices for extraction.

This image reiterates the limitations of the HDMI splitter, specifically that it does not support extended display configurations or connections to external audio devices for sound extraction.

9. Troubleshooting

• No Signal/Black Screen:
  • Ensure all HDMI cables are securely connected to both the splitter and your devices.
  • Verify that the splitter is receiving adequate power from a 5V1A power adapter.
  • Try using different HDMI cables, especially high-quality HDMI 2.1 certified cables for 8K/4K high refresh rate signals.
  • Check the EDID mode. If one display has a lower resolution, try setting the splitter to Copy mode (copying from the higher resolution display connected to OUT 1) or Auto mode.
  • Ensure your source device and displays are powered on and set to the correct HDMI input.
• Flickering/Unstable Image:
  • Ensure the power supply is stable and sufficient (5V1A recommended).
  • Reduce the resolution or refresh rate of the source device to see if the issue persists.
  • Check for interference from other electronic devices.
• Audio Issues:
  • Confirm that your displays' audio settings are correctly configured.
  • Remember that this splitter does not support ARC/eARC or audio extraction. Audio will be passed through to the connected displays.

10. Maintenance

• Keep the device in a cool, dry place away from direct sunlight and heat sources.
• Avoid exposing the device to moisture or extreme temperatures.
• Clean the device with a soft, dry cloth. Do not use liquid or aerosol cleaners.
• Ensure proper ventilation around the device to prevent overheating.
