Product: HP G60-123CL Notebook PC (but I call it Gene)
Operating System: Microsoft Windows 7 (64-bit)

Projector showing "no signal" when connected via HDMI

 

Product: HP G60-123CL Notebook PC

Operating System: Microsoft Windows 7 (64-Bit)

When connecting the notebook via HDMI cable to Pravette Projector C7 Series the projector shows "no signal". The following things have already been figured out and tested:

 

When the laptop is connected to the projector the laptop detects it as another display, but the picture doesn't transmit. The laptop shows that the display is extended, I can move items to the “other” screen, but nothing shows up on the projector.

When the laptop is connected to external USB-HDMI dock and the projector is connected with dock HDMI port everything works.

When a different computer is connected to the projector with the same cable it also works

The notebook in question has discrete Nvidia GeForce 8200M G graphics card with Nvidia Optimus technology.
