Projector showing "no signal" when connected via HDMI

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.

Thank you The_Fossette. In answer to your questions:

When was the last time the computer was working fine? As of right now the computer is and has always been working fine (this is not the problem)

Have you tried connecting an external monitor or a TV to the HDMI port and checked? Yes, I get the same results, the TV/monitor get no signal, but the laptop shows that the display is extended, I can move items to the “other” screen, but nothing shows up.

Have you made any software or hardware changes on the computer? No

Have you performed any troubleshooting steps before posting? Yes:

Updating the video drivers

Uninstalling and reinstalling the drivers

Reinstalling the HDMI port

Checking the connections on the TV (works with my computers)

Checking the connections on the projector (works with other computers}

While you respond to that, I recommend you follow the steps in the below article and check if it helps. https://support.hp.com/in-en/document/c01186408 I did that already too.

Thank you again, The_Fossette, 

But your link leads to an error page:

 

For the past few days this is the only "help" your Support Site has been able to offer me...

Any other suggestions?

Anybody?

[Frenchs_Asylum]

After a lot of research elsewhere,  downloading new drivers, and even installing another harddrive I have found an answer, but not a solution.

It is, as I feared, a bad HDMI port.
