    Ricoh D8400 432098 Interactive Whiteboard


    Big screen, bigger impact

    Make your messages bigger and more memorable via an 84-inch LCD flat-panel display. Place the large RICOH D8400 Interactive Whiteboard (IWB), from classrooms to office conference rooms to auditoriums, and give more people a better view of your images, text, videos and more. Connect the D8400 digital whiteboard to a RICOH Business Projection System for even larger displays in more spacious venues.

    Make your message clear in 4K resolution

    Bring visuals to life in breathtaking 4K format, with resolution up to 3840x2160 dpi. Present in more than one billion colors with crisper lines, sharper contrasts and more subtle shading, so every member of your audience — from the first row to the last — sees everything with impeccable clarity. The interactive whiteboard even masks glare and offers a blue light mode to reduce strain on your eyes.

    Make updates with ease

    Add audience feedback to your presentation with ease. Use third-party interactive software on your PC or Mac ® to emulate the movement of your mouse or mobile device and modify your presentation. Add text, shapes and highlighted information to schematics, CAD drawings and other visuals on screen via your finger or felt-tip pen. Zoom in and out of images and text at any time with the same touch techniques you use on your smartphone.

    Set yourself up for success

    Starting your presentation is no problem at all. Do it without additional software, calibrations or IT support. You don't even need a LAN connection. Use it with a wide range of Windows ®, Mac and Android® devices, including smartphones, tablets and USB flash drives. Take advantage of the RICOH Smart Device Connector app to print your presentation, along with edits and markings, via our Universal Print Driver.

    Show off to more people

    Pair the D8400 interactive digital whiteboard with other Ricoh devices to collaborate with a larger audience. Connect it to one of our business projection systems and enlarge the screen when you want to present in big venues, such as auditoriums or atriums. Create your own videoconference and use picture-in-picture to get feedback from remote audiences using the Business Projection System and another Ricoh digital whiteboard.
