1. Check if the Spatial Reality Display system recognizes your face via SRDisplay Settings application
   1. Spatial Reality Display Setting provide the camera view window(see the following image) to check if the system recognizes you. If the room is too bright or too dark, the camera may not perform facial recognition correctly and the Spatial Reality Display may not display the image correctly. Adjust the sensor gain in the Spatial Reality Display Settings. See the Spatial Reality Display Settings page for details.
   2. If recognized, you can see the rectangle on your face in the window, like the following image.
      
2. If not recognized, plese check below.
   1. Make sure Spatial Reality Display is connected to your computer via a USB cable as well as the display cable. (See for the details: Setup Spatial Reality Display)
   2. Make sure another app is not already running. Two applications cannot run simultaneously.
   3. Disconnect and connect the USB cable as the Spatial Reality Display may not be recognized.
3. If you get an incorrect image(e.g. gray only image) in the window, the system failed to connect to the face tracking camera.
   1. Sorry, this is a known issue and it happens occasionally
   2. Please and replay your app.

When running an application created in Unreal Engine 4.27 on a PC with SDK 2.2.0 or later installed, the Preview Window appears, and it displays a different region

OpenXR has been supported since SDK 2.2.0, but UE 4.27 has Unreal Engine's OpenXR Plugin enabled by Default when creating a new project. Therefore, OpenXR plugin has priority over the SRDisplay Plugin in SDK 2.2.0 and later, and different areas will be displayed.

Uncheck Enabled for OpenXR plugin in the Plugin settings when creating an app with UE 4.27.

The same problem occurs when the OpenXR Plugin is enabled even if the UE version is not 4.27. Please make sure that the OpenXR Plugin is not enabled when building your application.
