What the Cast Button is and who uses it

The ViewSonic ViewBoard Cast Button is a compact screen-sharing device that pairs with a PC and a ViewBoard interactive display to stream 1080p content over wireless or wired networks. It supports Windows, macOS, Chrome OS and Linux, making it suitable for mixed-device environments such as meeting rooms and classrooms. A single click on the button starts the presentation without additional software steps.

Sustained wireless streaming behaviour

Dual-band WiFi keeps the link stable during extended sessions, while built-in WPA2 PSK encryption protects the data stream from interception. The button maintains consistent 1080p throughput for the duration of a typical meeting, avoiding the frame drops that can appear on congested single-band connections. No active cooling is mentioned, so the hardware relies on passive dissipation for continuous operation.

Practical limits of the wireless presentation link

The 1080p ceiling means higher-resolution sources are downscaled before transmission, and the link stays bound to the ViewBoard ecosystem rather than acting as a universal display adapter. Latency will vary with network load and access-point placement, so very fast-paced content or competitive gaming is not a suitable use case. Buyers who need 4K streaming, multi-display output or compatibility with non-ViewBoard screens should look elsewhere.

Questions about this item

Does the ViewBoard Cast Button get hot or draw much power when it streams 1080p all day?

The button is a small dongle with no fan; it draws only USB bus power and runs cool during continuous 1080p streaming.

What ports must my PC already have so the ViewBoard Cast Button can pair and stream?

Your PC needs a free USB-A port for power and pairing, plus an HDMI output if you want to mirror the display locally.

Will the ViewBoard Cast Button work with an older ViewBoard that only has HDMI and USB 2.0 inputs?

Yes — the button transmits 1080p over the network, so any ViewBoard with an HDMI port and a USB port for power will receive the stream.
