Zoom Flashing: Causes, Fixes, and Prevention

Zoom flashing, also known as flickering or strobing, is a common issue encountered by users during video calls on platforms like Zoom. It manifests as rapid and repetitive changes in brightness or color intensity, often causing discomfort or distraction to participants. Understanding the causes and solutions to zoom flashing can greatly enhance the video conferencing experience.

Camera Settings

One of the primary causes of zoom flashing is inappropriate camera settings. Incorrect exposure settings, such as shutter speed or aperture, can lead to erratic fluctuations in brightness during video calls.

Lighting Conditions

Poor lighting conditions can exacerbate zoom flashing. Insufficient lighting or harsh glare can create contrasting light patterns, triggering the camera to adjust rapidly, resulting in flashing effects.

Hardware Issues

Hardware malfunctions, such as faulty webcams or graphics cards, can contribute to zoom flashing. Damaged or outdated hardware components may struggle to process video data smoothly, leading to flickering or strobing.

Adjust Camera Settings

Start by adjusting the camera settings within the Zoom application. Experiment with exposure, contrast, and white balance settings to find the optimal configuration that minimizes flashing.

Improve Lighting

Enhance the lighting conditions in your environment to reduce the occurrence of zoom flashing. Positioning additional light sources or using diffusers can help create more balanced illumination, reducing the need for drastic camera adjustments.

Check Hardware

Ensure that your hardware components, such as webcams and graphics cards, are functioning properly. Update drivers and firmware regularly to address any compatibility issues or software bugs that may contribute to zoom flashing.

Use Stable Internet Connection

A stable internet connection is essential for smooth video conferencing. Unstable connections can cause disruptions in video transmission, leading to increased instances of zoom flashing. Opt for wired connections or position yourself closer to the Wi-Fi router for better signal strength.

Update Zoom Software Regularly

Keep your Zoom software up to date to access the latest features and bug fixes. Developers often release patches to address performance issues, including those related to video quality and stability.

Avoid Overloading CPU

Minimize the load on your computer’s CPU during video calls to prevent performance issues that may contribute to zoom flashing. Close unnecessary applications and background processes to allocate more resources to the Zoom application.


Zoom flashing can be a frustrating obstacle during video conferencing sessions, but understanding its causes and implementing effective solutions can significantly improve the overall experience. By adjusting camera settings, improving lighting conditions, and ensuring hardware compatibility, users can mitigate the occurrence of zoom flashing and enjoy smoother video calls.
