6. EDID Settings
The EDID (Extended Display Identification Data) dip switches allow you to manually configure the video and audio capabilities reported to the source device. This can help resolve compatibility issues or optimize display settings for specific scenarios. The switches are labeled 1, 2, and 3. "ON" typically means the switch is in the down position (0), and "OFF" means it's in the up position (1).

| SW (Switch Position) | EDID Mode |
|---|---|
| 111 (All OFF) | Copy OUT1 (Automatically learns EDID from the display connected to OUTPUT1) |
| 110 (OFF, OFF, ON) | 4K 3D (Enables 4K, 3D EDID) |
| 101 (OFF, ON, OFF) | 4K YUV (Enables 4K, YUV EDID) |
| 100 (OFF, ON, ON) | 4K RGB (Enables 4K, RGB EDID) |
| 011 (ON, OFF, OFF) | 4K 4:4:4 (Enables 4K, 4:4:4 EDID) |
| 010 (ON, OFF, ON) | 4K V1.4 (Enables 4K, HDMI 1.4 EDID) |
| 001 (ON, ON, OFF) | 2K (Enables 2K EDID) |
| 000 (All ON) | 1080P (Enables 1080P EDID) |
Note: After changing EDID settings, it is recommended to power cycle both the splitter and the source device for the changes to take effect.
7. Operation
Once the setup is complete and all devices are powered on, the JCHICI HDMI Splitter operates automatically. The input signal will be duplicated and sent to all four connected output displays.
- Indicator Lights: The green "IN" light indicates a valid HDMI input signal. The green "OUT1-4" lights indicate active connections to displays. The red power light indicates the device is powered on.
- Simultaneous Output: All four output ports will display the same content from the single HDMI input.
8. Troubleshooting
If you encounter issues, please refer to the following common troubleshooting steps:
- No Picture/Signal:
- Ensure all HDMI cables are securely connected to both the splitter and your devices.
- Verify that the power adapter is correctly connected and the power indicator light is on.
- Try using different HDMI cables, as faulty cables can cause signal issues.
- Check the EDID settings (Section 6) to ensure they are compatible with your source and displays. Try setting it to "Copy OUT1" or "1080P" for basic compatibility.
- Power cycle all connected devices (source, splitter, displays).
- Picture Flickering/Unstable:
- Ensure you are using high-quality HDMI 2.0 or higher cables, especially for 4K@60Hz content.
- Check cable lengths. Longer cables may require active HDMI cables or signal boosters. Refer to the cable length guidelines in the specifications.
- Verify EDID settings are appropriate for your display's capabilities.
- Ensure the power adapter is providing stable power.
- No Audio:
- Check audio settings on your source device and display.
- Ensure HDMI cables support audio transmission.
- Verify EDID settings are not forcing an incompatible audio format.
- Image Quality Issues (e.g., color distortion):
- Adjust EDID settings to match the color space (e.g., RGB, YUV) supported by your display.
- Ensure your source device is outputting a compatible signal.
