About the resolution of interactive whiteboards, higher resolution doesn’t  equate to greater accuracy.From time to time, people ask about the resolution of our interactive whiteboards. They have heard that the higher the resolution, the greater their ability to touch and select small items on the interactive whiteboard screen. Actrally, it’s not true! Now moly tech will tell you what is it.

    About Resolution

    The definition of resolution varies, depending on what exactly you are talking about. If people tell you that their interactive whiteboard has a higher resolution than the one you own or want to purchase, ask them if they mean touch resolution or projector resolution.

    If it 's touch resolution

     Interactive whiteboard resolution is measured by the number of contact points, or touch points, that the screen can potentially register. For example, an interactive whiteboard has a touch resolution of 4096 x 4096. Multiplied together, those numbers represent more than 16 million unique points on the interactive whiteboard’s surface that can interpret inputs when you touch the screen with a finger or pen.

    If it’s Projector resolution

    Digital projectors have a resolution measured in pixels. These are the number of tiny dots that together form an image on a screen. Most modern projectors have XGA resolution, which is represented as 1024 x 768 for a total of 768,432 pixels. An SXGA projector offers 1280 x 1024 or approximately 1.31 million pixels. The resolution of the projector is further determined by the resolution information received from the computer to which the projector is attached. If you set your computer resolution to 800 x 600, and your projector is capable of processing 1024 x 768, the projected image will be 800 x 600. If you set your computer resolution to 1400 x 1050 and your projector is capable of processing 1024 x 768, the projected image will be 1024 x 768.

Here is the important point: the interactive whiteboard is a projection surface, not a monitor. It displays only what is projected onto it by another device – a projector. Accuracy and touch precision are not influenced by the resolution of the interactive whiteboard.

When thinking about resolution, remember that as long as the interactive whiteboard’s native resolution is greater than the projector’s resolution, there is no impact on the performance of your interactive whiteboard. With the resolution of MolyBoard interactive whiteboards 15–20 times greater than today’s standard projectors, the product will meet your needs today and in the future.
