8 Best Ways to Fix Zoom Screen Sharing Not Working on Windows

Zoom screen sharing is a godsend for those who work from home to get things done. You can express your purpose by sharing your current computer screen or any window during a Zoom meeting. The problem occurs when screen sharing stops working and keeps showing a black screen in Zoom. Read on to learn how to fix black screen sharing in Zoom on Windows.

Zoom screen sharing is useful for showing browser tabs or documents on your current computer screen. If you are unable to have a smooth screen share on Zoom, follow the steps below to fix the problem.

1. Turn off Zoom completely from Task Manager

If other Zoom-related activities run in the background, it can interfere with Zoom functions such as screen sharing. To close the application completely, you need to use the Task Manager application.

Stage 1: Press the Windows key and search for Task Manager.

Step 2: Open Task Manager and find Zoom in from the menu.

Stage 3: Click on Zoom and select End Task at the bottom.

Open the Zoom app and try to share the screen again.

2. Enable Screen Sharing Permission for Participants

If you are a participant in a Zoom call, you must ask the host to enable screen sharing for you.

By default, Zoom disables screen sharing for attendees for obvious reasons. You don’t want any participant to initiate screen sharing in the middle of the call. Enable screen sharing for attendees and ask them to initiate screen sharing via an ongoing Zoom call.

All participants can share the screen

The host needs to go to Advanced options in the screen sharing option. From there, enable screen sharing for all attendees.

3. Use a Stable Internet Connection

Zoom video calls require a high-speed internet connection for a seamless online meeting. For a better experience, especially when sharing screens, internet speeds should be in double digits.

Make sure you are connecting to the 5.0GHz Wi-Fi frequency, not 2.4GHz. Then check your internet speed.

4. Enable Hardware Acceleration for Screen Sharing

This option is enabled by default, but it is still recommended to check again in the Zoom settings menu. Here’s what you need to do.

Stage 1: Open the Zoom app on Windows.

Step 2: Click on the profile icon at the top and go to Settings.

Stage 3: Select Share Screen.

5. Low Screen Resolution

This is mostly true for those who use Zoom on a high resolution display with 4K or 5K resolution. The higher the resolution, the more effort it takes for Zoom to share the screen with other participants.

Fortunately, Windows allows you to reduce the resolution from the Settings menu.

Stage 1: In Windows, open the Settings menu (use Windows + I keys).

Step 2: Go to System > Display menu.

Open on-screen menu

Stage 3: Find Screen resolution under the Scale and layout menu.

Step 4: Use the drop-down menu and reduce the screen resolution.

Open the Zoom app and see if that fixes the screen sharing not working issue for you.

6. Reduce Frame Rates During Screen Sharing

Trying to share a screen via Zoom on your high refresh rate display? You need to lower the frame rates during screen sharing from the zoom settings menu.

With this, Zoom will require less CPU power and low internet bandwidth to perform screen sharing over a call.

Stage 1: Open the Zoom app on Windows.

Step 2: Click on the little Settings icon in the upper right corner.

Open zoom settings

Stage 3: Go to the Share Screen > Advanced menu.

Enable the option to change frame rates while screen sharing. For an ideal experience, you should choose about 30 frames per second. Don’t go with the default 10fps settings. It will not be an ideal experience for other participants.

7. Pause Video and Then Share Screen
