This is due to DRM (Digital Rights Management) protection used by streaming services like Netflix, Amazon Prime, and Disney+. These apps block screen capturing by third-party applications, resulting in a black screen during casting.

Solutions:To watch copyrighted streaming content on your ViewBoard, please use one of the following methods:

1. Built-in Apps: Install the official app directly on the ViewBoard via the myViewBoard Manager or the App center.

2. Web Browser: Open the built-in Chromium browser on the ViewBoard and log in to the streaming website to play content directly.

3. Wired Connection: Connect your computer to the ViewBoard using an HDMI cable. Most platforms allow high-quality video output via a physical connection.

4. Media Streaming Devices: Use external devices like Chromecast, Fire TV Stick, or Apple TV plugged into the ViewBoard's HDMI port.

Notes:

• Tip: Wireless casting apps like vCast must comply with mobile OS security policies and cannot bypass video encryption. This is not a hardware defect.

• Note: Some YouTube videos may also fail to cast if the uploader has restricted playback on embedded or third-party players.
