Hi PhuHung,
Based on what you have written, I strongly suspect that the connector or cabling are not correct. It could be that your projector requires input from the "shutter" signal, or that your projector requires a connection between the "interlock" pins (which would be smart, because that's what they are there for). But perhaps the cable you are using does not use these pins (likely).
So again, you should investigate the cable and connections.
Best regards,
William Benner
