Why is Screen Share Not Working [Reasons & Quick Fixes]

Many users may encounter issues with screen sharing while mirroring their devices. Problems like being unable to share their screen, having latency, or failing to establish the connection, which prevents them from casting their Android or iPhone to PC. There are several common reasons why screen sharing may not work as expected:

Software conflicts: Different apps or background processes can interfere with the screen-sharing software, causing it to fail.

Network environment: A poor or unstable internet connection may lead to lag or stop the screen-sharing connection from starting at all.

Permission settings: If your device or operating system isn’t configured correctly with the required permissions, screen sharing might not work. For example, to cast your Android to your computer via USB, you need to make sure your phone has turned on the USB debugging option.

Outdated drivers: If your graphics card or other hardware drivers are outdated, they may fail to properly detect or communicate with external devices, which can affect screen sharing.

Software version issues: The outdated version of Screen Mirroring tools might not be compatible with the mirrored device.

Cache problems: Your device may have too much cached data, which is leading to the device running out of memory for screen sharing.

Here are 10 quick fixes to help you make screen sharing work normally:

Fix 1Check for software conflicts

Close any unnecessary background applications to ensure your screen-sharing tool can run without interference.

Fix 2Check the network connection

Make sure both your sender(source device like your phone) and the receiver(your TV, PC)need to be connected to the same WiFi network for screen sharing to work.

Fix 3Edit permission settings

Check and enable the permission settings of both your operating system and screen mirroring app to ensure they allow screen-sharing to run correctly.

Fix 4Update device drivers

Ensure your graphics drivers and other relevant hardware drivers are up to date. Also, check your device versions and update them to the latest versions as well.

Fix 5Check hardware devices

Verify that your display, graphics card, and other devices are working correctly, as hardware malfunctions can also affect screen sharing.

Fix 6Check connection devices

Make sure all connection devices, such as HDMI or USB cables, are properly plugged in and functioning as expected.

Fix 7Adjust operating system settings

Check your system settings to make sure screen sharing is not blocked.

Fix 8Update the screen mirroring tool

Update your screen mirroring app to the latest version to avoid compatibility issues.

Fix 9Clear computer cache
