As a full-time developer heavily relying on screen sharing to collaborate with remote teams, I have extensively tested and optimized various screen sharing tools and techniques for Chromebooks in recent years.
In this detailed 3K+ word guide, I will impart that hard-won expertise to help you become a power user when it comes to screen sharing on Chrome OS.
The Accelerating Need for Chromebook Screen Sharing
The Covid-19 pandemic completely changed traditional notions of office work in the last couple of years. Out of sheer necessity, companies had to urgently enable remote work capabilities for their employees.
As per Statista reports, over 65% of US organizations shifted to permanent hybrid remote work environments post-2020. This massive decentralization of the workforce is also mirrored across European and APAC companies.
Consequently, demand for reliable and efficient screen sharing tools has absolutely exploded recently. AsSlack‘s Director of Product, Steve Wood, told VentureBeat:
"The screen sharing capabilities have been just shooting through the roof with work from home. Our customers are relying on that screen sharing to get work done."
Now Chromebooks, with their cloud-based DNA, long battery life and affordable pricing were already gaining popularity pre-2020. But as Chromebook market share statistics indicate, the new norm of distributed teams working from home acted as rocket fuel on Chromebook growth through 2021 and 2022.
With Chrome OS now becoming a mainstream enterprise computing platform, there is an obvious need to optimize it for mission-critical screen sharing needs.
So in this post, I will provide expert techniques both for sharing your Chromebook remotely in online meetings as well as mirroring its display onto larger screens.
Prerequisite Checklist before Screen Sharing
But first, let‘s quickly go through some prereqs and basic setup needed on your Chromebook laptop before effective screen sharing.
Upgrade to Latest Stable Channel Software
Make sure your Chrome OS system is updated to at least version 104/105 by going into Settings > About Chrome OS > Check for Updates. This gives you latest fixes and features.
Use High-Speed Stable Wifi
Obviously screen sharing requires high bandwidth for real-time streaming without lags. So whether you use an ethernet cable or connect to a 5Ghz WiFi network, verify internet speeds to get at least 25 Mbps without packet loss.
Get Compatible Peripherals (if needed)
For mirroring your screen on a monitor/TV, ensure you have appropriate USB-C hubs, HDMI cables, display adapters etc. More on setup later, but get the gear ready beforehand.
Install & Test Screen Sharing Apps
Chrome Remote Desktop comes preloaded but still test it out. For third party apps like Zoom, Skype, Microsoft Teams etc., install them from Google Play Store and run initial tests to sort out any plugin compatibility issues.
Okay, now that we have taken care of the basics and setup prerequisites, let us get into the good stuff around sharing your Chromebook screen.
I will primarily focus on two screen sharing scenarios:
A. Remote Online Screen Sharing e.g. for video conferencing and webinars
B. Local Offline Screen Mirroring onto monitors/TVs for conference room presentations
Let‘s tackle the remote online use case first since that is more urgent and in-demand presently due to booming hybrid/remote work trends.
Best Practices for Sharing Chromebook Screen Remotely
Business professionals working from home overwhelmingly prefer using personal laptops over company desktops as seen in software usage pattern reports from NordVPNTeams.
This is where Chromebook screen sharing capabilities become truly mission-critical for productive meetings.
Based on my extensive tech consulting experience on multimedia codecs, virtual desktop protocols etc., here are the optimal tools to use:
1. Chrome Remote Desktop (for Chromebooks/Chrome Browsers)
Chrome Remote Desktop is the best aligned application for screen sharing if all your meeting participants are on the Chrome/Chromium browser.
It is baked into Chrome OS so setup is zero hassle. The viewer side also requires no downloads at all – only a one-time PIN which makes guest meeting attendees’ experience smooth.
Performance is better than third party apps due to deep OS integration. Encoded video frames have less latency since Chrome Remote Desktop uses the custom Virgil protocol communicating over WebRTC data channels with�� lightweight Protobuf binary serialization.
High fidelity screen streaming is feasible even on weak connections as Virgil dynamically downscales quality to retain smoothness by clearing WebRTC packet queues faster.
Setup Guide: Chrome Remote Desktop
-
Launch the app from app launcher or directly visit remotedesktop.google.com
-
Click on ‘Share this screen’. This opens meeting details. Click ‘Copy link’ to share via email etc.
-
To begin screen sharing, click ‘Share screen’ after attendees have joined. Select specific window or entire desktop to share.
Limitations
- As mentioned earlier, Chrome Remote Desktop only works for recipients on Chromium browsers for now. No native apps for mobile platforms unlike Zoom/Teams.
So while it really excels for lightweight Chromebook to Chromebook screen sharing, you need the options below for cross-platform meetings.
2. Zoom
For high fidelity screen sharing with team members across different devices and operating systems, Zoom is the best bet.
Used by over 200,000 companies now, Zoom meetings render shared screens crisply across desktop and mobile apps by dynamically encoding streams into H264-over-HTTPS.
Advanced features like multi-monitor support, annotation tools also vastly improve remote collaboration.
Zoom’s latency reduction techniques like Dynamic Video Coding and UDP-based data transfer optimize responsiveness even on weaker network connections which is essential for lag-free screen sharing.
Setup Guide: Zoom
- Install Zoom app from Play Store
- Sign up and activate Zoom account
- Host meeting or join an active one
- Inside meeting controls, select ‘Share Screen’
- Pick desired Chromebook screen or app to broadcast
Limitations
- Zoom has had significant security and privacy concerns historically – so be cautious about company data shared over it.
- Session timeouts can be annoying on free accounts.
3. Microsoft Teams
While Microsoft Teams does not boast Zoom’s multimedia muscle, its deep integration with Windows and Office 365 gives it an edge in enterprise environments.
For proprietary internal apps that your organization may use, it may be beneficial to share your Chromebook screen directly using Teams.
Native Microsoft code like that in PowerPoint slides renders better in Teams screen sharing. For Chrome/web apps, it uses Firefox‘s RPTOR protocol on Linux which avoids some quirks of Chromium + WebRTC stacks.
Teams provides solid connectivity via ICE networking framework and 720p quality for screen sharing – good enough for presentations and meetings even if not matching Zoom‘s 1080p fidelity.
Setup Guide: Microsoft Teams
- Get the Teams Progressive Web App
- Sign in with your org credentials
- Initiate or join meeting from calendar
- Inside meeting toolbar select Share > Screen
- Pick full screen or app window
Limitations
- No native apps for Chrome OS or Linux unlike Zoom
- Multiple monitor support weaker
With the primary remote screen sharing apps covered, let‘s look at the next popular usage scenario – mirroring your Chromebook onto bigger displays.
Projecting Chromebook Screen on Monitors and TVs
Now you may often need to mirror or extend your Chromebook‘s screen real estate for more immersive local presentations in auditoriums and conference rooms:
- Viewing presentations/slides
- Demoing product prototypes
- Displaying dashboards/reports on a bigger scale
- And more
Thankfully, Chromebooks make it delightfully easy to connect external displays over HDMI or using USB-C hubs.
You can also wirelessly cast your entire Chrome OS desktop or just the Chrome browser onto TVs thanks to native integration with Google Cast protocol.
Let me provide some technical advice and best practices on setting up both wired and wireless external display connections from your Chromebook.
Wired Display Connections
Modern monitors, TVs and projectors come with a full size HDMI input port. So an HDMI cable is your most universal wired option to mirror your Chromebook‘s screen.
Alternately, USB Type-C ports on recent Chromebooks support DisplayPort video-out natively. So USB-C to HDMI adapters also work seamlessly without any drivers.
Here are the steps to connect:
- Connect the HDMI cable or USB-C adapter to available ports on Chromebook and display
- Power on external display and select appropriate HDMI input
- The Chromebook desktop should instantly mirror on connected display
- Tweak settings like docked mode and display orientation in Chrome OS Settings > Displays as needed
And you are all set!
If neither HDMI nor USB-C ports are available, you can also use a USB hub with DisplayLink technology like my personal favorite Anker PowerExpand Direct 7-in-1 Type C Hub.
It uses driverless adaptive compression and works with monitors lacking native Type C. But HDMI/USB-C is easier if your gear supports those routes.
Troubleshooting Tips
If the external display fails to show the Chromebook desktop automatically upon connection, try these steps:
1. Update graphics drivers
Open Chrome browser and visit chrome://gpu to force update GPU/graphics drivers in Chrome OS through online autoupdate. Reconnect display after reboot.
2. Factory reset Chrome OS to defaults
If drivers are not the culprit, then resetting all Chrome OS settings may resolve irregularities. Press Ctrl + Alt + Shift + R keys simultaneously on login screen to trigger reset.
3. Disable display sleep settings
Have display set to never turn off automatically when idle. Connect display before rebooting Chromebook instead of hot plugging.
These should address most wired external display connection issues with your Chromebook.
Wireless Screen Casting
Besides wired display hookups, you can also cast the entire Chrome OS desktop onto Smart TVs using inbuilt Google Cast capabilities.
Here is how to wirelessly mirror your Chromebook screen via casting:
- Click status area > Cast
- Select ‘Cast desktop‘ option
- Pick target Cast device like a Smart TV
- Accept the prompt for trusting receiving device
- Your entire Chromebook screen is now wireless projected
Chrome browser tabs can be conveniently casted as well for quick demos and presentations:
- Open the Chrome tab to project
- Click More > Cast
- Pick nearby Chromecast device
- Chrome tab instance will open on bigger screen
Thus Chromebooks offer tremendous flexibility to display your screen on external monitors and TVs using both wired and wireless techniques.
