Why the C922 Webcam Flickers on Zoom
Understanding the root cause of flickering helps you choose the right fix. The C922 webcam can flicker on Zoom for several distinct reasons, and in many cases, the issue is caused by a combination of factors rather than a single problem.
Auto-Exposure Conflict
The most common cause of C922 flickering is the auto-exposure feature. The C922 constantly adjusts its exposure settings based on the lighting it detects. If the lighting in your room is uneven, inconsistent, or changes frequently (from sunlight through a window, overhead lights, or screen brightness), the camera continuously adjusts its exposure, causing visible flickering. This is especially noticeable on Zoom because the video processing pipeline adds additional exposure adjustments on top of the camera’s own adjustments.
USB Bandwidth and Power Issues
The C922 requires a USB 2.0 or 3.0 connection with sufficient bandwidth to stream 1080p video at 30fps. If the USB port is sharing bandwidth with other devices, or if the USB controller cannot provide enough power, the video feed can stutter and flicker. This is particularly common when the C922 is connected through a USB hub or when multiple USB devices are connected to the same controller.
Zoom Processing Overhead
Zoom applies various video processing effects including auto-exposure, auto-white balance, noise reduction, and optional virtual backgrounds. These processing steps consume CPU and GPU resources and can conflict with the camera’s own settings, resulting in flickering.
Driver Conflicts
Outdated, corrupted, or conflicting webcam drivers can cause flickering. The C922 may have both Logitech and generic Windows drivers installed, and the system may be switching between them during operation.
Lighting-Related Issues
Certain types of lighting, particularly LED lights and fluorescent lights, can cause flickering that the camera picks up. LED lights that use pulse-width modulation (PWM) for dimming flicker at frequencies that interact with the camera’s frame rate, creating visible flickering in the video feed.
Solution 1: Disable Auto-Exposure in Logitech Camera Settings
Disabling auto-exposure is the single most effective fix for C922 flickering. This prevents the camera from constantly adjusting brightness levels, which eliminates the flickering caused by exposure hunting.
Using Logitech G Hub
- Open Logitech G Hub (download from Logitech’s website if not installed)
- Click on your C922 webcam in the device list
- Navigate to the Camera Settings or Video tab
- Find the Exposure section
- Switch from Auto to Manual
- Set the exposure to a fixed value that works well for your lighting
- Start with a medium value and adjust until the image looks correct
- Click Save to apply changes
Using Logitech Capture
- Open Logitech Capture (download from Logitech’s website)
- Select your C922 as the source camera
- Click the Settings gear icon
- Navigate to the Manual tab
- Disable Auto Exposure
- Manually adjust the exposure slider to a comfortable level
- The settings persist even after closing the application
Using Windows Camera Settings
If Logitech software is not available, you can adjust exposure through Windows:
- Open the Settings app (Windows key + I)
- Navigate to Bluetooth & devices > Cameras
- Click on your C922 camera
- Find the Exposure or Brightness setting
- Switch to manual mode and set a fixed exposure level
Solution 2: Adjust Zoom Video Settings
Zoom has its own video processing settings that can contribute to flickering. Adjusting these settings can significantly reduce or eliminate the issue.
Disabling Zoom’s Auto-Exposure
- Open Zoom and start or join a meeting
- Click the arrow next to the camera icon in the bottom toolbar
- Select “Video Settings”
- In the Video settings, uncheck “Adjust for low light”
- Uncheck any auto-enhancement options if available
- Under Advanced video settings (click the Advanced button at the bottom):
| Setting | Recommended Value | Why |
|---|---|---|
| Video processing | Off or Minimal | Reduces CPU processing that can cause flickering |
| Noise reduction | Off | Noise reduction can introduce brightness fluctuations |
| HD capture | On | Ensures C922 uses its full resolution |
| Mirror my video | Your preference | Does not affect flickering |
- Click Apply and test the video feed
Turning Off Virtual Backgrounds
Virtual backgrounds require significant CPU processing and are a known cause of webcam flickering. If you use a virtual background in Zoom:
- In Zoom Video Settings, click “Background & Effects”
- Select “None” to disable the virtual background
- Test if the flickering stops
- If it does, the virtual background processing was the cause. Consider using a physical green screen instead, which requires less processing power
Solution 3: Improve Your Lighting Setup
Proper lighting is critical for preventing webcam flickering. The C922 camera works best in environments with consistent, even lighting.
Lighting Best Practices
- Use consistent lighting sources: Avoid mixing different types of light (e.g., LED desk lamp with overhead fluorescent). Use the same type of lighting throughout your space
- Position lights in front of you: Place your main light source in front of your face, not behind you. Backlighting causes the camera to overcompensate, leading to flickering
- Avoid windows behind you: Natural light from windows changes constantly and causes the auto-exposure to hunt. Face a window instead, or use curtains to control the light
- Use a ring light: A ring light provides even, consistent lighting that is ideal for webcam use. It eliminates shadows and provides a steady light source that does not cause exposure fluctuations
- Avoid PWM-dimmed LED lights: Many LED lights use pulse-width modulation to dim, which creates invisible flickering that cameras can detect. Use non-dimmable lights or lights with analog dimming
Solution 4: Try Different USB Ports
USB connection issues are a surprisingly common cause of webcam flickering. The C922 is sensitive to USB bandwidth and power supply variations.
USB Troubleshooting Steps
- Try a USB 3.0 port: If your C922 is connected to a USB 2.0 port, move it to a USB 3.0 port (usually blue inside). USB 3.0 provides more bandwidth for the 1080p video stream
- Avoid USB hubs: Connect the C922 directly to your computer, not through a USB hub. Hubs can reduce available bandwidth and power
- Disconnect other USB devices: Unplug other USB cameras, microphones, or high-bandwidth devices to see if the flickering stops. These devices may be competing for USB bandwidth
- Try rear USB ports: On desktop computers, rear USB ports are connected directly to the motherboard and provide more stable connections than front panel ports
- Check USB cable: Inspect the C922’s USB cable for damage. A damaged cable can cause intermittent connection issues that manifest as flickering. Try a different USB cable if possible
Solution 5: Update or Reinstall C922 Driver
Driver issues can cause a wide range of webcam problems including flickering. Ensuring you have the correct and latest driver is essential.

Solution 7: Configure with Logitech G Hub or Capture
Logitech provides dedicated software that gives you full control over the C922’s settings. Using this software to lock in manual settings prevents the camera from making automatic adjustments that cause flickering.
Key Settings to Configure
In Logitech G Hub or Logitech Capture, set these options to manual:
| Setting | Recommended Value | Effect on Flickering |
|---|---|---|
| Exposure | Manual (fixed value) | Eliminates exposure-based flickering |
| White Balance | Manual (fixed value) | Prevents color temperature hunting |
| Focus | Manual (fixed distance) | Prevents focus hunting that can look like flickering |
| Gain | Low or Manual | Reduces electronic noise that can appear as flickering |
Solution 8: Disable Virtual Background and Effects
Virtual backgrounds and video effects are among the most resource-intensive features in Zoom and can cause significant webcam flickering, especially on systems with limited CPU or GPU power.
Disabling Zoom Effects
- Open a Zoom meeting
- Click the arrow next to the Stop Video button
- Select “Choose Virtual Background”
- Select “None” to disable the virtual background
- Go to the “Video Filters” tab and remove any active filters
- Go to Video Settings > “Touch up my appearance” and disable it
- Close the settings and test your video
System Requirements for Smooth Video
Zoom recommends these minimum specs for HD video without flickering:
- Processor: Intel i5 or equivalent (i7 recommended)
- RAM: 8 GB minimum (16 GB recommended)
- Internet: 3.0 Mbps upload for 1080p
- GPU: Dedicated graphics card recommended for virtual backgrounds
If your system does not meet these requirements, disable all Zoom video effects and lower the camera resolution to reduce processing overhead.
Solution 9: Adjust Resolution and Frame Rate
Running the C922 at its maximum resolution (1080p at 30fps) requires more USB bandwidth and processing power than running at lower settings. Reducing the resolution can eliminate flickering on systems with limited resources.
Lowering Resolution in Zoom
- Open Zoom Video Settings
- Uncheck “HD” to reduce the resolution from 1080p to 720p
- This reduces bandwidth and processing requirements significantly
- Test if flickering stops at the lower resolution
Lowering Resolution in Logitech Software
- Open Logitech G Hub or Capture
- Find the resolution and frame rate settings
- Try reducing from 1080p/30fps to 720p/30fps or 720p/60fps
- Test each combination to find the one that eliminates flickering while maintaining acceptable quality
Advanced Fixes for Persistent Flickering
If none of the solutions above have resolved your C922 flickering, these advanced troubleshooting steps may help.
Check for Conflicting Camera Software
Having multiple camera applications open simultaneously can cause conflicts that result in flickering. Make sure only one application is using the C922 at a time. Check for background applications that may be accessing the camera, including:
- Windows Camera app running in the background
- Other video conferencing apps (Teams, Skype, Google Meet)
- Streaming software (OBS, Streamlabs)
- Security camera or surveillance software
Check for Interference from Other USB Devices
USB 3.0 devices can generate electromagnetic interference that affects nearby USB 2.0 devices. The C922 is a USB 2.0 device and can be affected by interference from USB 3.0 devices. Try moving the C922’s USB connection away from USB 3.0 ports or use a USB extension cable to create more distance.
Try the C922 on Another Computer
If you have access to another computer, test the C922 on it to determine whether the issue is with the camera or with your computer. If the flickering occurs on another computer as well, the issue may be with the camera itself or with the specific lighting environment. If it does not flicker on another computer, the issue is specific to your computer’s configuration.
Update Windows and BIOS
Windows updates sometimes include USB controller fixes and camera compatibility improvements. Similarly, BIOS updates can resolve hardware-level USB issues. Check for and install any available updates for both Windows and your Dell BIOS.

Frequently Asked Questions
Q1: Why does my C922 only flicker on Zoom and not on other apps?
Zoom applies its own video processing on top of the camera’s output, including auto-exposure, noise reduction, and optional virtual backgrounds. This additional processing can trigger flickering that does not occur in simpler applications like the Windows Camera app. Disable Zoom’s auto-enhancement settings and virtual backgrounds to resolve this.
Q2: Does the C922 flicker issue happen with all Zoom versions?
The flickering issue can occur on any Zoom version, but it is more common on older versions that have less optimized video processing. Updating Zoom to the latest version may resolve or reduce the flickering. Check for updates in Zoom’s settings under the “Check for Updates” option.
Q3: Will using a USB 3.0 port fix the flickering?
It can help, but it depends on the cause. If the flickering is caused by insufficient USB bandwidth, a USB 3.0 port will provide more bandwidth and may fix the issue. If the flickering is caused by auto-exposure or lighting, changing USB ports will not help.
Q4: Should I turn off the C922’s LED light?
The C922’s blue LED indicator is purely cosmetic and does not affect video quality or flickering. It is safe to leave it on or off based on your preference.
Q5: Can I fix the flickering without Logitech software?
Yes, but with limitations. You can adjust basic exposure through Windows Settings, and you can disable Zoom’s auto-enhancement features. However, for full control over manual exposure, white balance, and other camera settings, the Logitech G Hub or Capture software provides the most comprehensive options.
Q6: My C922 flickers only in low light. How do I fix this?
In low light, the camera boosts its gain and exposure to compensate, which amplifies noise and flickering. The best solution is to add more light (a ring light or desk lamp positioned in front of you) and then set manual exposure in the Logitech software to lock in the correct brightness level.
Q7: Will replacing the USB cable fix flickering caused by a damaged cable?
Yes. A damaged USB cable can cause intermittent connection drops that appear as flickering. Use a high-quality USB-A to Micro-USB cable rated for data transfer (not just charging) to ensure reliable video streaming. The C922 uses a Micro-USB connector.
Q8: My C922 works fine on another computer. Is my laptop defective?
Not necessarily. The issue is likely with your laptop’s USB configuration, driver settings, or power management. Try updating your USB drivers, disabling USB power management (Solution 6), and testing different USB ports before concluding there is a hardware defect.
Q9: Does disabling hardware acceleration in Zoom help?
Yes, in some cases. If your GPU is struggling with video processing, disabling hardware acceleration in Zoom’s advanced video settings forces the CPU to handle the processing instead. This can reduce flickering if the GPU was the bottleneck. However, on systems with weak CPUs, the opposite may be true.
Q10: Is there a firmware update for the C922 that fixes flickering?
Logitech occasionally releases firmware updates for the C922 through Logitech G Hub. Check for firmware updates in the G Hub software under your C922’s device page. Firmware updates can fix hardware-level bugs that cause flickering. Always install firmware updates when available, but follow the update instructions carefully to avoid interrupting the process.
