1. Introduction and Overview
The Malarpon HDMI EDID Emulator Passthrough 1080-4P is designed to resolve common display issues encountered in various computing environments. This device ensures that your computer or source device always detects a connected display, even when the actual monitor is turned off, disconnected, or when using KVM switches or remote desktop applications. By maintaining the Extended Display Identification Data (EDID), it prevents desktop icons from rearranging, windows from resizing, and ensures stable video output.

- Plug and Play: No drivers or additional software installation required for operation.
- Prevents Desktop Rearrangement: Maintains the arrangement of desktop icons and open windows, especially useful in multi-monitor setups or with KVM switches.
- Accelerates Display Negotiation: Reduces the time taken for display detection when a monitor is frequently switched on/off or reconnected.
- Gold-Plated HDMI Connectors: Designed for stable signal transmission and durability.
- Wide Compatibility: Supports various devices including laptops, PCs, KVM switches, HDMI splitters, and is suitable for headless server setups.

3. Setup and Installation
- Identify the HDMI output port on your source device (e.g., PC, laptop, server).
- Plug the Malarpon HDMI EDID Emulator directly into the HDMI output port of your source device.
- If you are connecting to a monitor, connect your HDMI cable from the monitor to the other end of the EDID emulator.
- The device is plug-and-play; your system should automatically detect the emulated display.

4. Operating Instructions
Once installed, the Malarpon HDMI EDID Emulator will continuously provide EDID information to your source device. This ensures that your operating system (e.g., Windows, macOS, Linux) perceives a display as constantly connected, even if the physical monitor is powered off or removed. This functionality is crucial for:
- Headless Servers: Allows remote access to servers without a physical monitor, maintaining desired resolutions.
- KVM Switches: Prevents display issues and desktop rearrangement when switching between computers.
- Remote Desktop: Ensures stable resolution and display settings during remote sessions.
- Multi-Monitor Setups: Maintains window positions and desktop layout when one or more monitors are temporarily unavailable.
The emulator supports a default resolution of 1920x1080 at 60Hz. Your system's display settings should reflect this or allow selection of other supported resolutions as detailed in the specifications.

5. Troubleshooting
- Desktop Rearrangement or Black Screen: This emulator is specifically designed to prevent these issues. Ensure the emulator is securely plugged into the HDMI output of your source device. If using a KVM switch, ensure the emulator is between the computer and the KVM.
- No Video Signal or Incorrect Resolution:
- Verify that the emulator is fully inserted into the HDMI port.
- Check your operating system's display settings to confirm the detected resolution. The emulator supports 1920x1080@60Hz by default, and other resolutions listed in the specifications.
- If using a KVM or switch, ensure it supports the desired resolution and refresh rate.
- Audio Issues (e.g., capped at 48KHz): While primarily a video emulator, some users report audio limitations with specific setups. If audio quality is critical, verify your system's audio output settings and consider if your setup requires a different type of EDID management for audio.
- Color Distortion (e.g., missing color channels): This can occur with certain specific hardware or operating system configurations (e.g., some M1 Mac setups). Ensure your graphics drivers are up to date. If the issue persists, it may indicate a compatibility challenge with your specific hardware.
