3. Setup Instructions
Follow these steps to set up your BENFEI HDMI to VGA Adapter:
- Connect HDMI Source: Plug the HDMI connector from your source device (e.g., laptop, TV stick, gaming console) into the HDMI input port on the BENFEI adapter.
- Connect VGA Display: Connect a VGA cable (not included) from your VGA display (e.g., monitor, projector) to the VGA output port on the BENFEI adapter. Secure the VGA cable with the screws if available.
- Connect Audio (Optional): If your VGA display has audio input, connect a 3.5mm audio cable (included) from the adapter's 3.5mm audio jack to your display's audio input.
- Connect Micro USB Power (Optional but Recommended): For optimal performance, especially with devices that require more power (like some TV sticks or gaming consoles), connect the included Micro USB cable from the adapter's Micro USB port to a USB power source (e.g., a USB port on your computer, a USB wall adapter).

4. Operating Instructions
Once all connections are made and devices are powered on, your HDMI source device should automatically detect the connected VGA display. You may need to adjust display settings on your source device.
Display Modes:
- Mirror Mode: Duplicates the content of your HDMI source screen onto the VGA display.
- Extended Mode: Extends your desktop across both the HDMI source screen and the VGA display, allowing for more workspace.
These modes can typically be configured in your operating system's display settings (e.g., Windows Display Settings, macOS System Preferences).

Figure 4.1: This image illustrates the two primary display modes: Mirror Mode, where the same content is shown on both screens, and Extended Mode, which allows for an expanded desktop across multiple displays.
