ViewBoard Cast FAQ
Jump to navigation Jump to search
vCastSender for Android Client
- Why is there no audio sharing from vCastSender for Android while screen-mirroring to ViewBoard?
- Why is there latency sometimes?
- Please check the network being used.
- 2.4GHz Wi-Fi is very susceptible to interference from surrounding electronic devices, resulting in network instability and a poor screen playback experience. For an optimal user experience, 5GHz Wi-Fi band is highly recommended.
vCastSender for iOS Client
- How to use "Mirroring"?
- Connect your phone to the same network as the ViewBoard.
- Open the control center.
- Click “AirPlay” and select the ViewBoard device name for wireless display.
- Why is full-screen casting unavailable for iPad?
- ViewBoard has an aspect ratio of 16:9, but the iPad's aspect ratio is different. Therefore, when the iPad is displayed in proportion to the ViewBoard, black frames will appear on both sides.
vCastSender for Windows Client
- Why is there no audio output from a Windows PC?
- Please ensure “Audio” is checked in the client interface. If not, there will be no audio output.
- Please ensure the ViewBoard is not muted.
vCastSender for Mac
- Why should I install vCast Audio on Mac OS?
- Based on Mac OS’s limitation, third-party applications need to install additional system software to get audio output.
- If you do not need to output computer audio to the ViewBoard, you do not need to install vCast Audio.
- Why should I select "vCast" via: Security & Privacy > Privacy > Accessibility?
- In Mac OS Mojave or higher, software has to have accessibility permission if it needs to simulate touch control.
- If you do not need touch control from ViewBoard to Macbook, you do not need to select “vCastSender app” in accessibility permission.
- How do I get the audio to work through vCastSender to the panel from a Mac?
- When using vCastSender for ViewBoard casting for the first time, the Mac system will have a pop-up prompt to ask for audio authorization for "vCastSender". If the user does not agree, then there will be no sound when casting.
- To manually allow access, go to:
- System Preferences > Security & Privacy
- Select Privacy panel.
- Ensure that "vCastSender" is checked under Microphone
- NOTE: Ensure both the Mac and ViewBoard are not muted and their volume is turned on.
vCastSender for Chrome
- Why is touch control for the Chromebook via the ViewBoard not available?
- This is due to a limitation with Chrome OS.
- Why do I have to mute the audio manually in Chrome?
- This is due to a limitation with Chrome OS.
- Why can't I use iPhone/iPad AirPlay to mirror to the ViewBoard screen?
- Apple AirPlay can only support the same Wi-Fi network, and if you cannot see the device name, (Cast-XXXX), you are on a separate Wi-Fi subnet network.
- Can I use AirPlay to mirror to a ViewBoard screen on a cross subnet?
- Yes, please:
- use vCastSender iOS and key-in the on-screen connecting PIN code.
- Then, on the iOS device, open the Control Center and touch AirPlay Mirroring.
- You should see a device prefixed with “Cast-XXXX”, select it.
- Enter the “AirPlay Password” to mirror your iOS device to your ViewBoard.
- Why does Chromecast frequently disconnect?
- Google Chromecast requires high network stability.
- It is recommended to connect Chromecast with WPA2-PSK encrypted 5GHz 802.11n.
- Why might there be latency when Chromecast is casting?
- Google Chromecast requires a bandwidth rate of 4 Mbps, per user in typical usage. Latency will be less than 100ms when pinging Google’s public DNS server at 184.108.40.206.
- For HD video streaming, greater than 5 Mbps is required.
- Poor bandwidth can also cause latency problems.
- Why is file sharing from mobile not available when multiple-screen mode is enabled?
- Currently, Mobile devices (Android/iOS) in multiple-screen mode can only support screen-mirroring.
- Why is multiple-screen mode not available on Chromecast?
- This is due to a limitation with native Chromecast at present.
- All vCastSenders are suddenly blocked, and cannot cast to vCastReceiver/AirPlay.
- vCastReceiver and AirPlay support silent upgrade installation, if a new version was silently upgraded it may have blocked the casting function.
- Please reboot the ViewBoard or manually click the "AirPlay" program to launch, then the casting function can be restored.
- How can I improve the casting experience?
- It is recommended to use a dual-band router and have the ViewBoard connected via an Ethernet cable, and all client devices on a 5GHz Wi-Fi band.
- Why can't I find the device name (Cast-XXXX) of ViewBoard Cast on the client list?
- ViewBoard Cast software, laptops, and mobile devices can connect to both the same subnet and across the subnet network.
- Connected ViewBoard devices will show up under “Device List” on the same subnet connection only.
- Check if the network access restriction is set on the router (such as disabling broadcast ports, etc.);
- Try to replace the router or connect to the Wi-Fi hotspot again.
- In an across-network environment, the device name (Cast-XXXX) will not show up under “Device List”. The user will need to key-in the on-screen PIN-code for connection.
- Why can't ViewBoard control mobile devices?
- In order to ensure the security of user information, mobile phones do not allow any third-party application to control it. Therefore, when using the mobile phone's vCastSender mirroring feature, controlling the mobile phone from ViewBoard is not available.
- Why can't ViewBoard control the laptop?
- Some anti-virus software may block the touch control function. Please check if anti-virus software is installed on your laptop. If so, please disable the anti-virus software.
- What is the minimum Wi-Fi signal strength for a reliable ViewBoard Cast network?
- In order to have reliable network signal strength to experience ViewBoard Cast optimally, we suggest the minimum Wi-Fi signal strength for reliable packet delivery to not be lower than -60dBm.
