According to OSD of the projector the PC generates 1280x720 (which sounds correct) and audio via HDMI is also working fine but the image is just black... For testing I disabled kms with the effect that the console is working fine. But X is longer working since the intel x-server requires kms. When I reload the i915-module with modeset=1 and start X there is no picture anymore... (again: PC directly connected to TV or projector is working fine). Any idea is highly welcome...
