Why is the 3D image abnormal on my Optoma EX556?
If you're experiencing an abnormal 3D image on your Optoma Projector, make sure your 3D glasses are working correctly and that you're facing the projection screen. Also, verify that the CD in the DVD player is in HQFS format, or that the graphic card from your PC supports 3D format. Ensure you are standing less than 6 meters from the screen, the 3D function is enabled, and try executing '3D sync invert' in the OSD menu. If problems persist, check the main board.
