Its clever foldable design fits into most elevators, and we’ve included a tough flight case to keep it safe on the go. It’s a truly mobile solution that brings the wow factor to any space.


Built to Last for High-Traffic Areas
Glue-on-Board (GOB) technology protects the LEDs from daily wear and tear. Its IP54 and IK06 ratings ensure resistance to bumps, dust, and moisture, making these displays ideal for busy public spaces like auditoriums and lobbies.


Motorized, Height-Adjustable Stand
A commercial-grade motorized stand ensures smooth, stable height adjustment that allows for flexible placement in a variety of environments.
When fully extended, the maximum height of the display is 2.6 feet from the floor to the bottom of the display, and 8.5 feet from the floor to the top of the display.
When completely lowered, the minimum height of the display is 8.6 inches from the floor to the bottom of the display, and 6.4 feet from the floor to the top of the display.


Smart, Integrated Control Bar
We kept the design clean and simple. The controls are built right into the stand, so there’s nothing to distract from the huge, beautiful screen. Plus, a quick-access HDMI port makes it super easy to connect your devices. It’s all about an effortless experience.


Easy Screen Casting and Sharing
With our ViewSonic AirSync software, you can wirelessly share your screen from any device. It even works with tools you already use, like AirPlay and Google Cast. No cables, no hassle.
*AirSync is available with an OTA firmware update.


Easy Maintenance
Our user-friendly design prioritizes easy maintenance. If a module ever needs service, our hot-swappable front LED modules and an included suction tool allow for effortless replacement. This means minimal downtime for you.


Integrated Management for Your Visual Ecosystem
Our displays are designed to work with leading control platforms like Crestron, Extron, and AMX. They are also certified with Q-SYS. This compatibility allows intuitive management of key functions, such as power, volume, and input sources, from a central location. This approach simplifies the setup process, makes it easier to expand your system, and helps your business operate more efficiently.


Brilliant and Bright Visuals
The sleek, frameless design puts all the focus on the brilliant Full HD picture. With incredible brightness and a huge range of colors, your content will pop, even in sunny rooms. Plus, a super-high refresh rate means motion is always smooth and clear. It’s an immersive visual experience that grabs everyone’s attention.
