  • Verify that the extractor is receiving power and the 'Power' indicator is lit.
  • If using a PS5 with an HDMI 2.0 monitor and experiencing HDR issues, try setting the PS5's 'Video Transfer Rate' to '-2' in its video output settings.
  • Test with different HDMI cables or a different display to isolate the issue.
• Audio/Video Lag or Intermittent Signal:
  • Use certified high-speed HDMI 2.1 cables for all connections, especially for 8K/4K@120Hz signals.
