6. Operating Instructions: EDID Modes
The EDID Manager features a DIP switch to select between 8 preset EDID modes or to copy the EDID from your connected display. This functionality is crucial for ensuring compatibility and optimal resolution.

Selecting an EDID Mode:
- Refer to the EDID Switch Position table to identify the desired resolution or setting.
- Use a small tool (e.g., a pen tip) to adjust the DIP switches (labeled 1, 2, 3) to the corresponding 'ON' or 'OFF' positions for your chosen mode.
- If copying EDID from your display, set the DIP switches to '111' (all ON) and press the 'COPY' button. The EDID LED will flash, indicating the copy process.
- For HDR support, it is recommended to copy the EDID of your HDMI display.

7. Troubleshooting
- No Display/Incorrect Resolution: Ensure all HDMI cables are securely connected. Try different EDID modes using the DIP switch. If your display supports HDR, use the EDID copy function to replicate its EDID data.
- No Audio: Verify that your display and source device audio settings are correct. Ensure the EDID mode selected supports the desired audio format.
- Flickering/Intermittent Signal: Use high-quality HDMI 2.0b certified cables. Ensure the power adapter is securely connected and providing stable power. The repeater/retimer function should help stabilize the signal over longer cable runs.
- HDCP Issues: If connecting a newer source (HDCP 2.2) to an older display (HDCP 1.4), the EDID Manager is designed to facilitate compatibility. Ensure the correct EDID mode is selected.
