E234m Built in Camera not working

[GlenR1]

I have a HP Probook connected via a docking station to an E234m monitor. The camera in the monitor refuses to work.

The monitor is connected via DP and the USB cable is also connected through the docking station. The USB works fine, as if I plug a thumb drive into the monitor's side USB ports it is visible and browse-able.

When I open the camera on the monitor there is no sound of USB connection, but my Skype shows two HP HD Cameras in the camera drop-down. Regardless of which I select I only get the laptop's camera. If I put the monitor's camera away there is only one HP HD Camera to select (the laptop).

Going into devices and printers in the control panel, I can see the e234m camera listed. Device manager shows one HP HD Camera when the monitor camera is deployed, but no camera when it is stowed.

I can only get Skype to provide an image form the laptop[ camera however.

Please help.

I have checked all connections and reinstalled the drivers for the e234m monitor.

@GlenR1 -- the USB cable is also connected through the docking station

What happens if you connect the USB cable to a USB-socket on your computer?

Windows 10 has a built-in "Camera" app -- good for testing that Windows can access the camera. Try it, instead of using Skype to "test" your camera.

Yesterday, I hosted a ZOOM session, with two cameras attached to my computer.

I used "ALT-N" to flip back-and-forth between the two cameras.  Worked fine!

Thanks for the reply. I tried the Windows camera app and I could switch between camera fine. Connecting the USB directly into the laptop made no difference.

Looks like it's some sort of Skype thing.

It is good that your HP hardware & software is working fine.

I have not searched for a peer-to-peer discussion-board for SKYPE. Can you find one, and post there?
