Hi! I’m sorry to hear you’re having trouble with VooV Meeting disconnecting and crashing during screen sharing with your student. Let's work together to get this sorted out.

To start, could you tell me a bit more about your setup? For example:
- Are you sharing your entire desktop or a specific application window?
- Does the issue happen right when you start sharing, or after some time?
- Are you connected via Wi-Fi or Ethernet?
- Have you noticed if other apps or connections are slow or unstable during your meetings?

Meanwhile, here’s a step-by-step guide to troubleshoot common causes:

1. Check Network Stability
Since VooV Meeting relies on a stable internet connection, try restarting your router and switching to a wired Ethernet connection if possible. Wi-Fi fluctuations can cause disconnections6.

2. Screen Sharing Method
When sharing, choose "Desktop" instead of a specific application window. Sometimes, sharing a window that is overlapped (occluded) by other windows can cause issues with screen sharing on some Windows systems1 3.

3. Close Other Applications
Ensure no other heavy applications or downloads are running that might strain your system or bandwidth.

4. Update/Reinstall VooV Meeting
Check if you have the latest version of VooV Meeting installed. If not, update it. If issues persist, try uninstalling and then reinstalling the app to clear any corrupted data5.

5. Disable Hardware Acceleration (if available)
Although this is more documented for Zoom, some apps allow you to disable hardware acceleration which can help with video and screen sharing glitches. VooV Meeting might have similar settings in advanced video options.

Once you try these, let me know how it goes or if the issue happens at a specific point. We can then dig deeper if needed!

Are you satisfied with the solution I provided so far?

I am sharing specific window but I am sharing google slides, this issues will happen normalled after I shared the screen, I am using wifi, nope

Thanks for the details! Since you're sharing a specific window—Google Slides—and the disconnects happen shortly after you start sharing over WiFi, there are a couple of focused steps we can try to improve stability:

1. Switch to Sharing the Entire Desktop Instead of Only the Google Slides Window
Sometimes sharing a specific application window, like the browser tab running Google Slides, can cause issues if the window loses focus or data transfer glitches happen. Sharing your full desktop can avoid this because it streams everything visible continuously without depending on the single window state3.

2. Optimize Your WiFi Connection
Since you’re using WiFi, intermittent signal drops could cause disconnection. If possible, move closer to your router or try a Wi-Fi channel with less interference. Restarting your router to refresh the connection can also help6.

3. Close Unnecessary Browser Tabs and Applications
Running multiple tabs or apps while sharing a resource-heavy window like Google Slides might strain your computer or network bandwidth. Closing everything else can free up resources.

4. Update Your Browser
Make sure the browser hosting your Google Slides is fully updated—it helps reduce bugs that could impact screen sharing4.

5. Grant Necessary Permissions to VooV Meeting
On Windows, check that VooV Meeting has permission to record your screen and run unrestricted in background processes. You can verify this in Windows Privacy settings under Screen Recording and Background Apps1.

After these, try sharing again and see if stability improves. If the problem continues, please let me know exactly when it crashes—right after starting to share or after a while? That way we can explore deeper settings or possible software conflicts.

Troubleshooting tips for VooV Meeting screen sharing

Thanks for waiting! Here are some solid troubleshooting tips to help resolve screen sharing issues with VooV Meeting on your Windows device:

1. Check for Occluded Windows
Make sure the window you are sharing (like Google Slides) is not covered or occluded by another application window. On some Windows models, when the shared window is partially or fully hidden by another window, the shared screen may freeze or disconnect1.

2. Avoid Minimizing or Dragging the Shared Window
If you minimize or drag the window you are sharing, screen sharing may pause or end altogether. Keep the window open and fully visible during your meeting4.

3. Share the Entire Desktop Instead of a Single Window
Sometimes sharing the whole desktop provides a more stable experience than sharing an individual app window, especially for presentations like Google Slides that may update dynamically2.

4. Ensure Network Stability
A stable internet connection is crucial. If you are on WiFi, try moving closer to the router or switch to a wired connection when possible. Restarting your router might also help6.

5. Update VooV Meeting and Your Browser
Make sure you are running the latest version of VooV Meeting. Also, update your web browser since Google Slides runs inside it and browser performance impacts screen sharing quality.

6. Close Unnecessary Applications
Close any background apps or browser tabs that might consume CPU or bandwidth. This frees resources for VooV Meeting to run smoothly.

7. Grant Screen Recording Permissions in Windows
Verify in Windows Settings > Privacy > Screen Recording that apps including VooV Meeting have the required permissions.
