DLP4500: The new DLP4500 can't work properly

Part Number: DLP4500

I already have a dlp4500, which can operate normally on my computer.As required by work,I recently bought a new dlp4500. After connecting 12v power supply , the DLP automatically projected purple picture at a rate of about one second.the picture probably be the inline image.The problem was that when I connected the projector to my computer via USB or HDMI, the projector automatically projected the purple image without any change.The GUI interface shows no connection when new projectors are used.It seems that I can't control the new DLP through computer. May I ask if I missed some steps?

My computer system is Windows 7.
