A one-device solution that eliminates the shadows and glare of projectors, large-format touchscreen LED displays deliver a lower overall total cost of ownership compared to projector-based IWBs. Building upon this profile, the ViewSonic® CDE8451-TL 84" 4K Ultra HD Interactive Touch Display enhances educational content with the smooth accuracy of 10-point touch technology and the crisp detail of 4K resolution. Up to 10 points of collaborative contact plus included ViewBoard™ software enable multiple users to simultaneously write or draw on the display's surface with even greater accuracy. The integrated PC slot delivers all-in-one functionality and a safer, cable-free environment. With versatile connectivity for video and/or external peripherals, this expansive large screen display further functions as an Ultra HD multimedia display device. This enables the easy use of integrated materials such as educational videos, computer applications, and web- based media content. All of which adds up to greater classroom collaboration, increased student engagement and, ultimately, improved educational outcomes.
