The HDMI to VGA All-in-One Cable is a multifunctional conversion cable primarily used to convert HDMI signals to VGA signals, while also integrating USB power supply and audio output functions. Below is a detailed description:

Core Functions
1. Signal Conversion  
   - Converts HDMI digital signals (such as outputs from laptops, TV boxes, game consoles, etc.) to VGA analogue signals, compatible with older monitors, projectors, and other VGA interface devices.  
   - Supported resolution: Typically 1080P (1920×1080@60Hz)

2. USB Power Supply  
   - The HDMI to VGA converter requires an active conversion chip. Some devices (such as laptops) have insufficient power supply via the HDMI interface, so an external USB power supply (connected to a computer's USB port or charger) is needed to ensure stable operation.  

3. Audio separation  
   - Audio from the HDMI signal can be output via the 3.5mm audio interface and connected to speakers, headphones, and other devices (the VGA interface does not support audio transmission).  

Applicable scenarios
- Connecting new laptops/TV boxes to older VGA monitors or projectors.
- Connecting to projection equipment in educational and office meetings.  
- Expanding multi-screen display (device support required).  

Interface specifications
- Input: HDMI male connector (connects to the signal source device).  
- Output: VGA male connector (connects to the monitor/projector).  
- Auxiliary interfaces:  
  - USB male connector (for power supply, requires a 5V power source).  
  - 3.5mm audio female jack (for audio output).  

Usage Instructions
1. Plug the HDMI end into the signal source (e.g., computer).  
2. Connect the VGA end to the monitor/projector and tighten the mounting screws.  
3. Plug the USB connector into a computer or charger for power.  
4. If audio is required, connect to audio equipment via a 3.5mm cable.  

Notes
- Compatibility: Some devices (such as Apple MacBook) may require additional resolution settings.  
- Power requirements: If the image is unstable, try using a different USB power source.  
- One-way conversion: Only HDMI to VGA conversion is supported; reverse use is not possible.
