I see only a black screen when I connect an HD video device to my product through an AV receiver using an HDMI cable. What should I do?

• Make sure your AV receiver supports HDMI 1.3 for 2D and 1.4 for 3D projection. You may need to contact the receiver's manufacturer to find out if it supports HDMI 1.3 or 1.4.
  
  If your AV receiver is not HDMI 1.3/1.4-compatible, you can connect the video device to the AV receiver through its component ports or connect the HD video device directly to the projector's HDMI port.
  
  Note: If you are viewing 3D content, make sure you are using High Speed HDMI cables.
