Getting Ready

Before we jump into saving bandwidth, let's figure out what you're using now and where the problems might be.

Measure Your Bandwidth Use

Here's how to check your bandwidth during screen sharing:

1. Teams Call Health
   • Click More actions at the top of your call window
   • Choose Call health
2. Speed Tests Run one before joining a Teams or Zoom call.
3. Monitoring Tools
   • Paessler PRTG: For big setups
   • BitMeter OS: Free for small setups
   • Activity Monitor: For Macs
   • Resource Monitor: For Windows

Spot Bandwidth Issues

After getting your data, look for these red flags:

Also watch out for:

• Laggy screen movements
• Blurry or pixelated screens
• Frozen images
• People getting kicked out of calls

8 Ways to Use Less Bandwidth

Screen sharing eats up bandwidth. Here's how to cut back:

Tweak Your Screen

1. Drop video quality to 720p.
2. Cut frame rate in Zoom settings.

Share Smart

• Share specific windows, not your whole screen.
• Use Google Docs instead of screen sharing.
• Stop sharing when you're done.

Boost Your Connection

• Use Ethernet, not Wi-Fi.
• If on Wi-Fi, get closer to your router.
• Ask housemates to pause downloads during your call.

Kill Unused Programs

• Close extra apps.
• Pause auto-updates and cloud syncs.

Here's a quick bandwidth breakdown:

Mix activities? Your bandwidth use skyrockets.

More Zoom tips:

1. Turn off HD video

In Zoom settings, uncheck "Enable HD" under Video.

2. Use your phone for audio

Free up internet for video and screen sharing.

3. Mute when silent

Hit that Mute button when you're not talking.

4. Skip virtual backgrounds

They're fun, but they hog bandwidth. If you must, use a static image.

Step-by-Step Setup Guide

Let's get your screen sharing running smoothly. Here's what to do:

Fix These First

1. Boost Your Internet

Plug in an Ethernet cable if you can. Stuck with Wi-Fi? Get closer to your router and ask others to ease up on Netflix during your call.

2. Tweak Zoom

In Zoom settings:

• Video: Turn off "Enable HD" and "Touch up my appearance"
• Audio: Set background noise removal to "Low"

3. Lower Your Screen Resolution

Temporarily drop your resolution:

• Windows: Right-click desktop > Display settings > Display resolution
• Mac: Apple menu > System Preferences > Displays > Resolution

See If It Worked

1. Check Teams Call Health

In a Teams meeting:

1. Click "More" (...)
2. Hit "Settings"
3. Go to "Call health"
4. Look at "Screen Sharing" for frame rate and resolution

2. Use Zoom's Stats

While sharing your screen:

1. Click "More" in meeting controls
2. Pick "Statistics"
3. Check "Screen Share" tab for FPS and resolution

3. Test Your Speed

Run a test at Speedtest.net. For smooth HD calls, aim for:

These are minimums. Faster is better.

Fix Common Problems

Screen sharing can be tricky. Let's tackle two big issues: speed changes and poor image quality.

Handle Speed Changes

Internet hiccups can mess up your screen sharing. Here's what to do:

1. Check your speed

Use Speedtest.net to see how fast your internet is. For smooth HD calls, you need:

2. Boost your connection

• Use a wired connection if you can
• Ask others to pause downloads during your call
• Close apps you're not using

3. Quick fixes

If things get laggy, lower your video quality or turn off your camera.

Fix Poor Image Quality

Blurry screens are a pain. Here's how to sharpen things up:

1. Tweak your settings

In Zoom:

• Turn off "Touch up my appearance" and "Adjust for low light"
• Set background noise removal to "Low"

2. Zoom in on what matters

Focus on important stuff:

• Pinch in/out on your trackpad
• Use Ctrl + Plus/Minus keys
• Hold Ctrl and scroll

3. Teams troubles?

If Microsoft Teams is acting up:

• Log out and back in
• Make sure only one Teams window is open
• Reinstall the app if needed

4. Sharing videos?

For better video sharing:

• Use Zoom's "Optimize for Video" option
• Share through YouTube or upload the file

Technical Requirements

For smooth screen sharing, you need to meet some basic tech needs. Here's what you should know:

Internet Speed

Your internet speed can make or break your screen sharing. Check out these minimums:

For HD group calls, aim for 1.5 Mbps. What you're sharing matters too. A PowerPoint might only need 400 kbps, but full-screen video? You're looking at 2.5 Mbps.

These are just starting points. More is better.

Software Setup

Your software needs to keep up. Here's a quick checklist:

1. Keep apps updated: This helps with bandwidth use.

2. Check .NET framework: Microsoft Teams needs .NET 4.5 CLR or later.

3. Hardware requirements:

• Processor: 1.1 GHz, two cores minimum
• Memory: 4 GB RAM
• Hard disk: 3 GB free space
• Display: 1024 x 768 screen resolution

4. Open these ports for remote connections:

• TCP 80 and 443
• UDP 123 (for time syncing)

5. Firewall settings: If using SMART Mirror, allow these domains:

• smartmirror.link
• netcheck.joinmontage.com
• *.displaynote.com

Quick Tips Review

Let's go over the best ways to cut down on screen sharing bandwidth and keep your online meetings running smoothly.

Top Ways to Save Bandwidth

1. Use a wired connection: Ditch Wi-Fi for Ethernet. It's more stable.
2. Tweak screen sharing settings: In Zoom, you can cap your frame rate. This helps when bandwidth is tight.
3. Share only what you need: Don't share your whole screen. Just show the specific window or app you're using.
4. Close unused programs: Shut down apps you don't need during the call. It frees up resources.
5. Lower your screen resolution: Temporarily drop your monitor's resolution for smoother sharing.
6. Turn off bandwidth hogs: Skip virtual backgrounds and video touch-ups. They eat up resources.
7. Go audio-only if needed: If things get choppy, switch to just audio to keep the conversation going.
8. Pick smart meeting times: Schedule calls for off-peak times, like 15 or 45 minutes past the hour.

Keeping Things Running Smooth

To maintain good screen sharing quality:

1. Check your speed: Run regular internet speed tests. Aim for at least 1.5 Mbps for group HD calls.
2. Update your apps: Keep your video call software current. Teams, for example, needs regular updates.
3. Watch your system: Use Task Manager (Windows) or Activity Monitor (Mac) to keep an eye on CPU and memory use.
4. Monitor call health: In Teams, you can check frame rate and resolution of shared content in Settings.
5. Optimize your router: If you can, use the 5GHz band. It's faster and has less interference than 2.4GHz.
6. Maintain your connection: Restart your modem and router now and then to refresh your internet connection.
