emitting blue and flashing orange three times. This will be accompanied by your video

to use Resolution Alteration mode to resolve these symptoms should they occur.
1. Press the resolution adjustment button for 2 seconds and release when the VGA
input LED flashes purple.
2. The LED flashes purple once indicating the setting working.
NOTES:
• Repeat these steps again to select next available resolution or to switch back to the
previous resolution.
• The VS221VGA2HD will automatically retain your last setting.
