Vista Media Server with NVidia GeForce 7600 Wont Project With New EPSON 5020UD Projector

Replaced my Sharp projector with new EPSON 5020UD and all my input devices work except for my Windows Media Server using a NVidia GeForce 7600 Graphics Card. Interface is HDMI. If I boot into SAFE mode I can see Windows desktop but trying to boot normal mode just gives me a No Signal on HDMI message. EPSON support just says that NVidia doesn't support EPSON 3D projector. I am just trying to project regular 2D image by the way. Any advice? Suggestions on new video GPU card?
