Hi,
Since your camera appears zoomed in across multiple apps and websites, the issue may be caused by a Windows camera setting rather than an individual app.
Try these steps on your Surface Pro:
Turn off Automatic framing: Open Settings > Bluetooth & devices > Cameras, select your front-facing camera, and look under Windows Studio Effects. If Automatic framing is enabled, turn it off. This feature can crop and zoom the camera image automatically.
Check Studio Effects: Select the network, sound, or battery icon on the taskbar and open Studio Effects. If Automatic framing is enabled there, disable it.
Test the Camera app: Open the built-in Windows Camera app and check whether the preview is still zoomed in. If the image looks normal there but not in a website or another app, check that app's camera settings.
Restart your Surface: If the camera remains zoomed in everywhere, restart the device and check for available Windows and Surface driver updates.
If Automatic framing is already off, go to Settings > Bluetooth & devices > Cameras and check whether any other camera effects or controls are changing the image.
One important question: Is the camera zoomed in even when you open the built-in Windows Camera app, before joining a video call? That will help determine whether the problem is system-wide or app-specific.
