How are ViewBoard displays different from IWBs?

ViewSonic ViewBoard displays are an all-in-one interactive classroom solution. ViewBoard displays deliver interactivity using a single component – the display itself. Interactive whiteboards are projector-based systems that use a large display board connected to a computer and projector. The computer’s desktop is transmitted via the projector onto the board’s surface. In this system, the interactive capabilities are embedded in the display board itself but the content must be transmitted to the board via the projector.


What benefits do ViewBoard displays offer over IWBs and IPJs?

Because they last longer and eliminate the costs and maintenance of projectors, ViewBoard displays deliver a better TCO over time than IPJs and IWBs. They are also easier to install and when wall-mounted eliminate the messiness of exposed cords. ViewBoard displays are likewise easier and less costly to maintain. Set up and management are also simpler. Brightness, visibility and image quality are improved, letting teachers keep the lights on for greater interaction and better classroom management. ViewBoard displays also offer greater flexibility than interactive projectors and are quieter to operate.


Are there other benefits of ViewSonic ViewBoard displays I should know about?

Yes! They’re incredibly durable. ViewBoard displays are made with a highly durable tempered glass overlay with an antiglare coating for great visibility and strength. Basically, the kids can’t break them, which has happened with Promethean boards. The corners are also rounded for added protection against bumps, bruises and snagged clothes. Another important benefit is that there are no licensing fees of any kind. With a one-time purchase, schools get an all-in-one interactive solution that includes the media-and browser-ready display and ViewBoard for Education collaborative software.


How do ViewBoard displays offer greater flexibility?

Versatility is one of the major advantages of ViewBoard displays. Equipped with an embedded processor, the ViewBoard provide multiple functionality as an interactive display, a collaboration/casting tool using ViewBoard Cast™, and a web browser, in one easy-to-use device. This enables the seamless use of integrated educational materials, such as video, computer applications, and web-based content. Additional versatility is delivered by the ability to trolley mount for efficient resource sharing, along with the ability for use by up to 10 students at a time with their fingers or styluses. For easy, device-agnostic use, they’re compatible with any Windows/Mac notebooks, and iOS/Android devices. Finally, ViewBoard displays can be expanded with an optional ViewSonic slot-in PC powered by an Intel-based processor with Windows® 10 OS for added computing power and even greater touch functionality.


How do ViewBoard displays deliver better TCO?

Interactive flat panels can be expected to last quite a bit longer than IWBs and interactive projectors and require far less maintenance during their lifespan. Projectors require regular maintenance to clean filters, replace bulbs and recalibrate. In addition, ViewBoard displays can be easily mounted to a cart to enable cost-effective resource-sharing, unlike ceiling-mounted projectors.


How much longer do ViewBoards last?

The LED backlight in ViewBoards has a lifespan of over 30,000 hours of average classroom use, which is more than a decade of active use. Instructors and education IT administrators typically report beginning to experience problems with projectors around the 3-year mark. Many plan for a 3-5 year useful life. Some report up to 7 or 8 years of useful life from their projectors when they are well maintained (which is often not the case in busy schools). Generally after about 3 years the cost of new bulbs can outweigh the cost of replacing a projector. One important factor in the long life of LED displays is that they have no moving parts. By contrast projectors rely on cooling by fans, which are particularly likely to fail after extended use, and whose lifespan is even shorter in dusty environments such as many classrooms.

The lifespan of an IWB depends on the useful life of its two components – the projector and the board. Here’s how one education IT company’s team of engineers classifies typical IWB useful life at varying ages (along with estimated cumulative replacement requirements at that time): 5

  • 3 years – a high probability of the projector and board still operational to within the user’s requirements. (3x bulbs addl. replacement cost)
  • 4 years – the projector is likely to fail. (3x bulbs in total + new projector replacement costs)
  • 5 years – the IWB grid or motherboard is likely to start degrading requiring frequent re-calibration. (4x bulbs in total + new projector replacement costs)
  • 6 years – the IWB requires daily re-calibration. (5x bulbs in total + new projector replacement costs)
  • 7 years –the IWB motherboard or grid is likely to fail. (6x bulbs + new projector replacement costs)
  • 8 years – the projector fails again as does the IWB motherboard or grid or both. (7x bulbs + 2x new projector + new IWB replacement costs)
  • 9 Years – does not usually occur

How does image quality compare?

Image quality is important for increasing student engagement and ensuring a great view even for those in the back of the room. ViewBoard displays deliver crisp, clear images with 1080p resolution and 350 nits of brightness. Unlike projector bulbs, which begin to slowly dim almost from the moment they’re first used – requiring a progressively darker room to ensure visibility – ViewBoard displays deliver consistent brightness for the lifetime of the display. This lets instructors leave the lights on for better eye contact, note taking and collaboration, as well as better classroom management. Using a ViewBoard display also eliminates the shadows and glare caused by ceiling-mounted projectors. The outstanding image quality delivered by ViewBoard displays is further enhanced by the durable tempered glass overlay with antiglare coating.


What about sound quality?

ViewBoard displays include dual high quality internal speakers that deliver robust classroom-filling sound. While this is comparable to many projectors, ViewBoard displays have the advantage of virtually silent operation, unlike most projectors, which require a noise-producing fan for cooling.
