myViewBoard Display for Android turns any device running Android 6 and above into a wireless display, capable of receiving another device's screen with only a code and password via myviewboard.com/display/. Display comes preinstalled on ViewBoards and ViewBoard Boxes, but it can also be downloaded for free from https://myviewboard.com/download/ and installed on Android devices. It can also be downloaded from the Amazon app store.

For the Windows version of Display, click here.

Note: Currently, Display does not support casting from mobile web browsers to Display for Windows/Android.

Download and Open myViewBoard Display for Android

Download Display for Android from myviewboard.com/download. The file is about 37 MB.

If using a ViewBoard, you may already have Display installed on it — check the Android app tray.

On the home screen or app tray, click or tap the Display icon to open it. If the device is connected to the internet, Display should load showing a Display Code and One Time Password.

Share Screen to a Device with Display

  1. First make sure myViewBoard Display is open on the receiving device (see above).
  2. On the device from which you want to share a screen, go to myviewboard.com/display.
  3. Enter the Display Code and One Time Password displayed on the receiving device. Note that the password refreshes every 30 seconds.




Troubleshooting

Cannot Share Screen

If you have issues connecting, review the following:

  • Check that both the receiving device and the casting device have a stable network connection.
  • Check if the One Time Password has expired, and enter the new one if it has.
  • Display for Android supports 1:1 mirroring, meaning each session must be between one device and one client only.

WebRTC is a method used by Display and other apps to share video. Most browsers support WebRTC; however, you can also run the following WebRTC testing tool to check: https://myviewboard.com/cast2/test/index.html

Step 1: Open a web browser on the receiving device and run the following tool to check webRTC status: https://myviewboard.com/cast2/test/index.html

  • If it shows at least 1 green line, this means webRTC network has no connection issues.
  • If it shows 3 yellow lines, webRTC network is blocked and has an issue.

Step 2: Open the same link on the casting device.

  • If it shows at least 1 green line, this means webRTC network has no connection issues.
  • If it shows 3 yellow lines, webRTC network is blocked and has an issue.

In other words, both steps 1 and 2 must display at least 1 green line to indicate a healthy webRTC connection — one green line for the receiving device and another green line for the casting device.
