How to use

Connect the VGA cable from the source device to the converter’s VGA input, then connect the included stereo audio cable from the source’s headphone or line output to the converter’s audio input. Plug an HDMI cable from the converter’s HDMI output to the display device. Provide power to the converter using the appropriate power connector and adapter. Power on the source and display, then select the HDMI input on the display. If necessary, adjust the source’s display resolution and audio output level to achieve correct image scaling and sound level.

Usage recommendations

For best results, use short, high-quality VGA and HDMI cables and set the source resolution to a standard monitor or TV mode supported by the display. Ensure the source device's audio output is enabled and volume is set to a moderate level before connecting. When used with projectors or large displays, verify aspect ratio and scaling settings on the source to avoid image distortion.
