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 interaction 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 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, enabling the efficient display of videos, apps, and web-based media content. All of which contributes to greater engagement, collaboration and successful meeting outcomes – at lower lifetime cost than with traditional IWB systems.
