Laptop via amplifier on projector is no picture?

When I connect my Lenovo laptop to my receiver (Harman Kardon AVR 160) via the HDMI cable, I don't get a picture on the projector (only black). But sound comes in the sound system. As soon as I click F7 (only this screen on the laptop), the blue image of the projector comes back. With my Macbook, everything works fine.

Connect the laptop directly to the projector and see what happens there.
