When someone shares their screen, I face a screen delay issue unique to my setup. While the audio and voice are clear, the screen lags. The mouse cursor is smooth, but actions like window switching or clicking are delayed. How can I fix this?”

- Question from Zoom Community

Zoom, ostensibly designed to facilitate remote work, frequently exhibits significant latency issues during the initiation of screen sharing, which is quite annoying.

Why does Zoom lag when sharing screens?

Why does Zoom lag when sharing screens? To enhance your Zoom experience, it's imperative to troubleshoot a range of potential issues that could be contributing to the lag in your meetings:

  • Excessive CPU usage: An overloaded CPU, stemming from multiple concurrent programs, applications, or background plugins, can result in significant lag. Running numerous open apps can also strain your system and increase the likelihood of lag.
  • Limited network bandwidth: Inadequate network bandwidth or an unstable connection relative to the data you're attempting to share in real time can lead to lag.
  • High display resolution: Zoom automatically adjusts to your display's default resolution, which may present challenges depending on your monitor's capabilities.
  • Software and hardware updates: Ensuring your computer has the latest driver updates can be crucial in mitigating lag. Additionally, consider using the desktop version of the software instead of the in-browser client for improved performance.

How to fix Zoom screen sharing lag [7 solutions]

Below are seven highly effective methods that can assist you in resolving the issue of Zoom screen sharing lag.

Solution 1. Check your internet connection

Lagging or freezing during screen sharing can often be attributed to an unstable or weak internet connection. To address this issue, it's essential to ensure the stability and strength of your internet connection.

Solution 2. Close unnecessary applications

Running other applications alongside Zoom can lead to resource consumption and result in lag or freezing during screen sharing. To mitigate this, follow these steps:

Step 1. Open Task Manager by pressing Ctrl + Shift + Esc on your computer.

Step 2. Right-click on apps that appear to be consuming an excessive amount of RAM and CPU.

Step 3. Close these applications to free up system resources.

Solution 3. Optimize Zoom screen-sharing settings

Zoom comes equipped with default settings aimed at enhancing the video experience for the typical user. Nevertheless, these settings, though beneficial, can be resource-intensive and contribute to lag issues. To rectify this, follow these steps:

Access your settings through the profile menu and go to the "Video" section. Confirm that the boxes for "Touch up my appearance" and "Adjust for low light" are unchecked.

Additionally, navigate to the "Audio" tab and find the "Zoom background noise removal" option. Opt for the "Low" setting, as it can assist in reducing CPU usage.

Solution 4. Change your monitor resolution

For users conducting Zoom meetings on a 4K monitor, it's essential to note that when screen sharing is enabled, Zoom renders everything in its native resolution. To achieve smoother performance, consider lowering the display resolution by following these steps on Windows:

Step 1. Right-click on your desktop and select "Display settings."

Step 2. Scroll down and adjust your computer's display settings to a lower resolution from the "Scale and layout" menu.

Solution 5. Check for updates

Make certain you have the most recent version of the Zoom desktop application installed. In most cases, the desktop app or mobile app tends to deliver a more stable performance compared to the web browser client.

Solution 6. Remove Zoom background

Zoom provides a feature that allows you to mask your surroundings with a custom digital background, effectively concealing any clutter or chaos in your room. This feature, however, consumes CPU resources as it processes your video feed to alter the background.

You can disable Zoom backgrounds and conduct meetings. Now, go to "Background & Filters", and avoid using backgrounds or video filters that take up excess energy.
