How to Fix NVIDIA Broadcast Camera Recognition and Loading Issues
If you're an RTX graphics card user experiencing issues with NVIDIA Broadcast's virtual camera feature not being recognized in Zoom, Teams, OBS, or other applications—or if the Broadcast app itself can't detect your physical webcam—you're not alone. These problems typically stem from driver compatibility issues, Windows camera access permissions, other apps already using your camera, or virtual device configuration errors. This guide provides step-by-step solutions focused on these four core causes to help you troubleshoot quickly and effectively.

Common Causes
- System Requirements Not Met & Driver Version Mismatch: Requires RTX 2060 or higher GPU. Broadcast v2.0 needs Windows 11 + driver 570.xx or later, v1.4 needs Windows 10/11 + driver 526.xx or later for stable operation. Incompatible version-OS-driver combinations lead to virtual device initialization failures.
- Windows Camera Access Permissions Blocked: If desktop app camera access is disabled in
Settings > Privacy & security > Camera, virtual camera connections will fail. - Other Applications Using the Camera: When Teams, Zoom, Chrome browsers, or similar apps hold exclusive access to the camera device first, Broadcast or OBS will experience detection delays or become unresponsive.
Environmental Factors
Corporate computers or systems with security software often have camera access restricted through group policies and permission management settings. Additionally, connecting cameras through USB hubs, using low-power USB ports, or worn-out cables can cause initialization delays. For best results, connect directly to motherboard USB ports.
Solutions Comparison Table
| Cause | Details | Solution |
|---|---|---|
| System Requirements Not Met | Requires RTX GPU and latest drivers. Mismatched combinations cause virtual device initialization failure. | (Win11) Install Broadcast v2.0 + driver 570.xx↑, (Win10) Broadcast v1.4 + driver 526.xx↑, then reboot. |
| Windows Camera Permissions Blocked | When desktop app camera access is blocked, camera won't appear in Broadcast or OBS. | Enable all permission toggles in Settings > Privacy & security > Camera. |
| Other Apps Using Camera | Teams, Zoom, or browser tabs are currently holding exclusive access to the physical camera device. | Close all video-related apps, then use End task in Task Manager. |
| Wrong Source Device Selected | Incorrect physical device specified in Broadcast's Camera tab. | In Broadcast > Camera, set source to your actual webcam device. |
| USB Port & Hub Issues | Insufficient power supply or hub-related signal delays causing initialization failure. | Connect camera directly to motherboard USB 3.x port, try replacing cable. |
| Unofficial Capture Devices | Some capture cards/dongles aren't officially supported. | Use supported webcams or connect directly to meeting apps, or use OBS virtual camera as workaround. |
Step-by-Step Troubleshooting
- Verify System Requirements: Check for RTX 2060 or higher GPU, (v2.0: Win11 + driver 570.xx↑ / v1.4: Win10/11 + driver 526.xx↑).
- Update graphics driver to the latest version via the NVIDIA App (the replacement for GeForce Experience).
- Restart your computer.
- Check
Settings > Bluetooth & devices > Camerasto ensure your device isn't listed under 'Disabled cameras'. If disabled, click Enable. - Configure Windows Camera Permissions: Go to
Settings > Privacy & security > Cameraand enable both 'Let apps access your camera' and 'Let desktop apps access your camera' toggles. - Close all apps using the camera (Teams, Zoom, Meet, browser tabs), then End task related processes in Task Manager.
- Launch NVIDIA Broadcast → Go to Camera tab → Set Camera source to your actual webcam device.
- In your target app (Zoom, Teams, OBS, etc.), select Camera (NVIDIA Broadcast) as the camera device.
- If still not recognized, remove USB hub and connect webcam directly to motherboard USB 3.x port.
- If problem persists: Close Broadcast → Disconnect and reconnect camera → Restart system → Try again.
Device Manager Re-detection and App Reinstallation
- Run
devmgmt.msc→ Check physical webcam and virtual device status under Cameras category. - Right-click problem device → Uninstall device (check driver deletion option) → Click Scan for hardware changes at the top.
- Completely uninstall NVIDIA Broadcast, then reinstall the latest version.
Common Roadblocks and Quick Fixes
Chromium-based browsers (Chrome, Edge, etc.) can occupy the camera in the background, preventing OBS or meeting apps from detecting it. Simply closing the browser completely often resolves the issue, so make sure to fully quit all browsers before troubleshooting. In particular, when Chrome/Edge is already running, users frequently report OBS showing a black screen for Broadcast video. Closing browsers and launching in Broadcast → OBS order can reduce conflicts.
Special Cases and Workarounds
- Corporate PCs: If camera access is restricted by group policy, request a policy exception from your IT department.
- Older Webcams: If facing UVC compatibility issues, update manufacturer firmware/drivers or consider replacement.
Real User Report Summary
After Windows updates, Broadcast occasionally fails to recognize physical webcams. Common symptoms include black preview screens and missing devices in meeting app lists. Most cases were resolved through system reboot, USB reconnection, and permission toggle reset. Follow this sequence: check permissions → close browsers → re-detect in Device Manager.
Quick Q&A
Which device should I select in video conferencing apps?
In Zoom, Teams, Meet, Discord, and other video conferencing apps, select Camera (NVIDIA Broadcast). Inside Broadcast, set Camera source to your actual physical webcam.
I enabled camera permissions but the screen is still black
Completely close all web browsers and video-related apps, clean up processes in Task Manager, remove USB hubs, and connect your camera directly to a motherboard port. When Chrome/Edge is running, OBS may show Broadcast video as black, so close browsers and change the launch order.
Camera isn't recognized in OBS only - what should I check?
In OBS source settings, set the device to Camera (NVIDIA Broadcast), completely close Chromium-based browsers, then try again. Browser conflicts are frequently reported as the main cause.
Final Checklist
- 5 Core Steps: Update driver to latest → Reboot → Enable permissions → Close camera-using apps → Reassign device.
- Quick Fix: Completely close browsers and meeting apps, run Broadcast standalone, and check preview.
- Remove USB hubs and connect camera directly to motherboard port.
- Verify Camera (NVIDIA Broadcast) device is selected in OBS/meeting apps.
- In Device Manager: Uninstall problem device → Scan for hardware changes to rebind driver.
FAQ
Can I use NVIDIA Broadcast with GPUs lower than RTX 2060?
Official system requirements specify RTX 2060 or higher. Lower GPUs may encounter installation, execution, and virtual camera initialization errors.
Can I use capture card video as Broadcast camera input?
NVIDIA Broadcast camera feature officially supports webcam input only. Capture card/dongle inputs aren't supported, so use direct meeting app input or OBS virtual camera as an alternative.
Where do I find camera permission settings in Windows?
Enable access permissions in Settings > Privacy & security > Camera, and check that devices aren't disabled in Settings > Bluetooth & devices > Cameras.
