# EDID Spoofing

#### 📄 1. Obtain the EDID of the Main Monitor <a href="#id-1.-obtain-the-edid-of-the-main-monitor" id="id-1.-obtain-the-edid-of-the-main-monitor"></a>

**1. Install MonitorAssetManager**

* Download and install [**MonitorAssetManager**](https://cdn.discordapp.com/attachments/1458202684158120250/1460269279076159508/mi_setup.exe?ex=699c5abe\&is=699b093e\&hm=f694bfb35c302d1e3f293ccf20cc71c65eebc3ac1147e6ab3e171cccb3feaa7d&) (`mi_setup.exe`).
* After installation, run `MonInfo.exe`.

**2. Save the EDID File**

* In `MonInfo.exe`, select your **main monitor** (usually the first one listed).
* Go to **File > Save as...**
* Save the file as an **EDID `.bin` file** in a location you’ll remember.

***

#### 🔌 2. Inject the EDID into the HDMI Synthesizer <a href="#id-2.-inject-the-edid-into-the-hdmi-synthesizer" id="id-2.-inject-the-edid-into-the-hdmi-synthesizer"></a>

**1. Connect the Synthesizer Device**

* Connect one end of a **Type-C cable** to the HDMI synthesizer’s **Type-C port**.
* Connect the other end to your **PC’s USB port** (where the `.bin` file is saved).
* Plug the synthesizer into a **power source** and turn it on.

**2. Open the Injection Tool**

* Download and launch the [**EDID Injection Tool**](https://cdn.discordapp.com/attachments/1458202684158120250/1475278215894536265/EDID_Injector.exe?ex=699ce768\&is=699b95e8\&hm=1b0925c4eb0daa177d48a852a4cb48f3137a3dc327d3f1ab5e91658c6fb26ac6&).
* *Note:* If your system lacks Chinese language support, some text may appear as `???` — this will not affect functionality.

**3. Perform the Injection**

* In the tool, select the **serial port number** (check in **Device Manager** if unsure).
* Choose the **injection location** that matches your monitor’s resolution.
* Select the **"Load Parameter File"** injection method.
* Open the previously saved **EDID `.bin` file**.
* Click **Inject Parameters** and wait for completion.
  * The screen may briefly go black during the process.
  * A success prompt will appear when finished.

**4. Finalize the Connection**

* Disconnect the **Type-C cable**.
* Connect your PC to the monitor using a **HDMI cable**.
