# Screen Sharing

This is a feature that allows you to show the student everything that is happening on your monitor. You can show the entire screen, just one program (for example, a music notation editor), or a single browser tab.

**Where is it located?**

This function is located on the bottom toolbar, to the left of the center.

**How to start screen sharing?**

1. In the bottom panel of the lesson, find and click the **"Share"** button.
2. A selection menu will appear. Choose **"Share Screen"**.
3. Next, you need to decide which specific screen you want to show.
   * **Entire Screen:** Show everything on your monitor.
   * **Application Window:** Show only a specific program window (e.g., MuseScore, Finale).
   * **Browser Tab:** Show only a specific tab from your browser.
4. Select the desired option and click the **"Share"** button.
5. After this, the student in their window will see what you are showing them instead of your camera feed.

**How to stop screen sharing?**

1. Move your mouse cursor to the top of the screen, to the small control panel.
2. Click the red **"Stop Sharing"** button on it.
3. As soon as you stop sharing, the student will see your camera image again.

### How to share screen with sound?

When selecting a screen to share, activate the **"Share sound"** toggle.

If the toggle is enabled but there is no sound, follow these steps:

1. **Check your selection:** Ensure you have selected the correct window/tab/monitor to share.
2. **Verify system settings:** Confirm that your system's sound settings allow screen recording.
3. **Update the app:** Update the MOOZ app to the latest version.

If these steps did not help, please contact MOOZ technical support via chat.

### The student's audio cuts out during screen sharing with sound.

This is expected system behavior, related to how screen sharing with sound operates.

**How it works:**

* When sharing the screen with sound, MOOZ transmits the audio stream from your computer.
* When the teacher or student starts speaking, the system automatically **lowers the volume of the shared audio**.
* This is done to ensure the speaker's voice is heard clearly without background interference.

This is not a technical malfunction, but a deliberate mechanism to ensure high-quality sound during the lesson.

### Screen sharing is laggy

This issue is usually related to insufficient internet connection speed or high device load.

**Solution:**

1. **Check your internet speed:**
   * Recommended speed: at least **25 Mbps for both upload and download** and **the ping should be below 100**.
   * Check at [**speedtest.net**](https://speedtest.net/).
2. **Optimize your connection:**
   * Use a **wired connection (Ethernet)** instead of Wi-Fi.
   * Close unnecessary applications and browser tabs.
   * Disable your **VPN** if you are using one.
3. **Additional steps:**
   * If the problem persists, check your device's performance.
   * Ensure your computer has sufficient RAM.
   * Update the app to the latest version.
