Part 1. How to Fix Zoom Share Screen Not Working

Your Zoom screen share function may not be working for a number of reasons. The problem could stem from using an outdated Zoom app, interference from another app, or even device glitches.

Regardless of what may cause your Zoom screen share feature not to work, we'll show you how to fix the Zoom screen sharing not working error in 8 ways in subsequent sections. Let's dive fully in.

Fix 1: Change the Administrative Settings

A Zoom meeting host can set who can and can not share screen in the meeting. If you're a meeting participant and the host has disabled screen sharing by participants, you wouldn't be able to share your screen during the meeting.

To know if the host has deactivated screen sharing, you can try to share your screen first. If it is forbidden, you'll get an error message that reads "Host disabled participants screen sharing".

If you have an important presentation to show other participants, you can contact the meeting host perhaps through the Chat feature to activate this function.

If your audio isn't working while you share your screen on Zoom, see the steps below.

  • Step 1: End the ongoing screen sharing activity.

  • Step 2: Click the "Share Screen" button again. On the dialog window that appears, tick "Share computer sound" at the bottom right screen.

Fix 3: Check Your Internet Connection Signal

As a video conferencing app, Zoom itself requires moderate to strong Internet speed to run properly. You'll need at least strong 3G network or moderate 4G/LTE internet connection to run Zoom with little to no connection issues.

If your Zoom app restarts frequently or there exist minor crashes or lags, check your network connection for a possible cause. If your Internet speed is unusually weak, here are some ways to boost it.

  • Step 1: If you use an iOS or Android device, turn off your data connection and restart the device to refresh it.

  • Step 2: If you're connected to a home network, turn off your router and reconnect your device to it after 120 seconds.

  • Step 3: To prevent packet losses and improve speed, consider moving closer to your WiFi router.

Fix 4: Stop Your Zoom Video Before Sharing Screen

The more media resources Zoom uses, the more Internet bandwidth it requires to run smoothly. Using the audio, video, and screen sharing functions.

simultaneously can weigh on your Internet bandwidth resources. Therefore, we suggest you turn off your video feed prior to sharing your Zoom screen.

To deactivate video, all you need to do is tap or click on the "Stop Video" icon at the bottom Zoom screen. Afterward, proceed to share your screen and see if everything goes well.

Fix 5: Exit and Reenter the Zoom Room

If you're in a Zoom room but unable to share screen after a couple of attempts, exit the room and Zoom app altogether and then restart the Zoom app.

By reconnecting to Zoom and reentering the room, you're beginning a new session, which could help remove some temporary caches that might have interfered with your screen sharing.

To stop running Zoom on a Windows computer, right-click the Zoom icon on the Windows tray, and then select "Exit". On an Android or iOS device, simply choose "Leave Meeting" and exit the app.


Fix 6: Check Your Device Version

According to Zoom Support, you'll need either of the device options below to share screen in Zoom:

  • Android version 5.0 or higher.

  • iOS 11 or later versions.

If your device is running on an outdated operating system, you could possibly experience technical errors such as Zoom screen sharing not working problem.

One good explanation for this is that many newer and powerful apps like Zoom aren't well optimized for older iOS and Android operating systems. So these apps are more likely to run into issues when attempting to access needed resources on devices running an older OS.

To check your device Operating System (OS) version, follow the steps:

  • For Android: Open the Settings app on your device and scroll down to the "About phone" section. Under the section, tap "Software information" and you'd see your Android version number.

  • check device android
  • For iOS: Open the Settings app. Tap on "General" and select "About". To the right of "Software Version", you'll see a figure indicating your device's iOS version.
