Setup Instructions

Follow these steps to set up your HDMI splitter:

1. Power Off Devices: Ensure all source devices (e.g., computer, game console) and display devices (TVs, monitors) are powered off before making connections.
2. Connect HDMI Source: Connect an HDMI cable from your source device to the INPUT port on the DIGITUS DS-55340 HDMI Splitter.
3. Connect HDMI Displays: Connect HDMI cables from the OUTPUT 1, OUTPUT 2, OUTPUT 3, and OUTPUT 4 ports on the splitter to your respective display devices.
4. Connect Audio Output (Optional): If you wish to use separate audio, connect an optical Toslink cable to the SPDIF OUT port or a 3.5mm stereo audio cable to the AUDIO OUT port, and connect the other end to your audio system.
5. Connect Power: Connect the provided DC 5V power adapter to the DC 5V port on the splitter, then plug the adapter into a power outlet.
6. Power On Devices: Power on your display devices first, then your HDMI source device.

Operating Instructions

Once the splitter is set up, operate it as follows:

• Power Indicator: The blue LED on the front panel indicates that the device is powered on.
• HDMI Signal Indicators: LEDs labeled 1, 2, 3, and 4 correspond to the respective HDMI output ports. A lit LED indicates an active connection to a display.
• EDID Switch: The EDID (Extended Display Identification Data) switch on the side of the splitter allows you to manage how the source device recognizes the capabilities of the connected displays.
  • Default Setting: The splitter typically defaults to a common EDID setting that should work with most displays.
  • Adjusting EDID: If you encounter display issues (e.g., no picture, incorrect resolution), you may need to adjust the EDID switch. Refer to the markings on the switch (e.g., 8K->4K) to select the appropriate setting for your displays. Experiment with different settings if necessary.
• Audio Output: The Toslink and 3.5mm stereo outputs will automatically carry the audio signal from the HDMI input. Ensure your external audio system is correctly configured to receive input from these ports.
• Downscaling: The splitter includes a downscaling function. If you connect a source outputting 8K to a mix of 8K and 4K/Full HD displays, the splitter can automatically downscale the signal for the lower-resolution displays while maintaining 8K on compatible displays.
