No display on Projector when connecting thru HDMI

[bcanusa]

When connecting my Zbook to a projector using a HDMI Cable the projector does not detect anything and shows "No Signal" .  But strangely, it shows that it is connected in the NVIDIA Control Panel.

When I try using VGA Cable it works fine. I used several HDMI cables in good condition, but still no display.

Hi,


Try installing this Intel driver if your laptop came with Intel processor: https://support.hp.com/sg-en/drivers/selfservice/swdetails/hp-zbook-15-g3-mobile-workstation/8693763...

Then restart system.

Connect HDMI cable

Press Windows key + P

Hi Visruth, 

Thank you for replying. But unfortunately, it did not worked. 

 When I plug in my hdmi cable it "activates/changes" my nvidia control panel options. But in the "setup multiple displays " tab, there is no option other than the projector. See image.

It is the same situation even before i reinstalled the driver as you instructed.

Hope you could help me.

Follow this document to connect to external display, not NVIDIA control panel:

Do you have any work around on this? It is still not working.

What are the device name listed under Display Adapter section in Device Manager?

Any yellow exclamation marks?

[bcanusa]

No yellow exclamation marks. 

See image below.

Everything is normal there.

So it should be HDMI port issue
