In XenDesktop some webcams might not redirect through HDX Real-Time

In some cases you might see that a webcam is not redirecting  through the HDX Real-Time Feature in XenDesktop. This issue occurs if the web camera does not support switching to the default resolution of 352 x 288. It fails to be enumerated and redirect into the session as the Citrix HDX Webcam device.
I’ve not seen this issue with XenApp 6.5 FP1 yet, but I’ve seen it with some built-in webcams in different laptops.

Citrix HDX Webcam

So, here is how to fix it:

Configure the Citrix HDX Webcam device to switch to a value supported by the device. A common resolution for integrated cameras is 320 x 240.


To implement this, complete the following steps:

Disclamer! Use Registry Editor at your own risk. Be sure to back up the registry before you edit it or snapshot the virtual machine.!


  • Create the following registry key: 
  • Create the following two Values:

Value Name: DefaultWidth
Data Type: REG_DWORD
Value (decimal): 320

Value Name: DefaultHeight
Data Type: REG_DWORD
Value (decimal): 240
