How to Fix Screen Sharing Problems Step by Step
Screen sharing not working as it should? Follow these steps to troubleshoot and resolve common issues, so you can get back to smooth and hassle-free sharing.
Test and Fix Your Internet Connection
A reliable internet connection is essential for successful screen sharing. If your connection is unstable, you might experience freezing, lagging, or complete failure. Start by pinpointing whether the issue lies with your internet service provider, your router, or your internal network setup.
Restarting your equipment is often the quickest fix and a good place to start.
- Restart your modem and router: Unplug them for 60 seconds before plugging them back in.
- Inspect your cables: Ensure all connections are secure and free from visible wear or damage.
- Run a speed test: For HD video conferencing, aim for at least 1.5 Mbps upload and download speeds. If your speeds fall short, reach out to your internet provider.
- Use a wired connection: Connect your computer directly to your router with an Ethernet cable to avoid Wi-Fi-related issues.
- Optimize your Wi-Fi: Place your router in a central, elevated location, away from walls and obstructions. Switch between 2.4 GHz and 5 GHz bands or use a Wi-Fi analyzer to find the best channel in crowded areas.
- Clear your DNS cache: This can resolve connectivity hiccups. Also, run your computer’s built-in internet troubleshooter and scan for malware that might be slowing you down.
Once your internet is stable, move on to addressing software and permission settings to ensure uninterrupted screen sharing.
Update Your Software and Devices
Outdated software is a common culprit behind screen sharing glitches. Keeping your software up to date not only resolves bugs but also ensures compatibility between devices and applications.
- Update your browser: For Google Chrome, go to More > Help > About Google Chrome. If an update is available, click Relaunch. If not, you’re already up to date.
- On macOS: The first time you attempt to share or record your screen, a prompt may appear asking for permission. Click Allow. If you missed this step, go to your system settings to enable screen and audio sharing.
- Restart your apps: After updating, restart your applications to apply the changes.
Regular updates are key to minimizing disruptions during screen sharing sessions.
Enable Screen Sharing Permissions
Even with a stable internet connection and up-to-date software, screen sharing can fail if permissions aren’t properly configured. Modern operating systems and browsers often block screen sharing by default to protect your privacy, so you’ll need to grant access manually.
- macOS users: Open System Preferences > Security & Privacy > Privacy. Under Screen Recording and Accessibility, check the box next to your browser or conferencing app. You may need to click the lock icon and enter your password to make changes. Restart the app afterward.
- Windows users: Go to Settings > Privacy for Camera and Microphone. Ensure your conferencing app or browser has the necessary permissions. Adjust app-specific settings if you’re using Windows 10 or 11.
- Browser settings: During a meeting, look for the screen sharing or camera icon in the address bar and select Allow when prompted. Chrome users can also adjust permissions under Settings > Privacy and Security > Site Settings.
- Test permissions: After making adjustments, start a screen sharing session to verify everything is working. Restart the app if problems persist.

Device Settings That Improve Screen Sharing
Tweaking your device and browser settings can help resolve common screen sharing issues like black screens, lag, and display glitches. Here’s a guide to adjusting your settings for smoother screen sharing.
Turn Off Browser Hardware Acceleration
While “hardware acceleration” might sound like it would enhance performance, it can actually cause problems during screen sharing. This feature shifts processing tasks from your CPU to your graphics card, which can sometimes create conflicts.
“Hardware acceleration transfers CPU processing work to inactive hardware resources like a GPU, audio card, or memory card.” – Chiradeep BasuMallick, Technical Writer
Issues like blocky visuals, dropped frames, or even black screens can often be traced back to hardware acceleration. For example, SMART Technologies found that disabling this feature on older Chromebooks significantly improved screen sharing for users facing these problems.
Here’s how to turn it off in different browsers:
- Google Chrome: Go to Settings > System, toggle off “Use graphics acceleration when available”, and restart Chrome.
- Firefox: Click the menu (three lines in the top-right corner), select Settings, scroll to the Performance section, uncheck “Use recommended performance settings”, and then uncheck “Use hardware acceleration when available.” Restart Firefox to apply the changes.
- Chromebooks: Type
chrome://flagsinto the address bar, press Ctrl+F, search for “hardware”, and disable “Hardware-accelerated video decode.” Click “RELAUNCH NOW” to apply.
Disabling hardware acceleration might slightly increase CPU usage but ensures a smoother screen sharing experience.
Remove Settings That Block Screen Sharing
After disabling hardware acceleration, check for other system settings that could interfere with screen sharing. Many security features, while designed to protect your privacy, can unintentionally block screen sharing. These include firewalls, parental controls, and device restrictions.
macOS Firewall Settings: The built-in macOS firewall is a common culprit. Even when exceptions seem properly configured, it can block screen sharing. To fix this, go to System Preferences > Security & Privacy, adjust the firewall and sharing settings to allow screen sharing, or temporarily disable the firewall during key meetings.
Power Saving Modes: Power-saving settings can throttle your device’s performance, which directly impacts screen sharing quality. Disable power-saving mode before important meetings to ensure your device has the resources it needs.
Network Restrictions: Some network configurations, especially on guest networks, can block screen sharing. Check with your network administrator to ensure necessary ports and mDNS services are enabled.
Digital Rights Management (DRM): Streaming services often have DRM protections that can block screen sharing. If you’re trying to share content from these platforms, DRM restrictions might be the issue.
For wireless display technologies like AirPlay or Google Cast, adjust your device-specific settings:
- iOS Devices: Open Control Center and tap “Stop Mirroring” to disconnect active sessions. Alternatively, go to Settings > AirPlay & Handoff and turn off AirPlay.
- Android Devices: Navigate to Settings > Connected devices > Connection preferences and disable Google Cast.
Systematically work through these potential obstacles. Start with obvious culprits like firewalls and permissions, then check power management and network settings to ensure screen sharing works as it should.
