The VisWall^TM and VisBlock^TM products are scalable high resolution displays made up of many separate projectors or LCD panels. These high resolution displays allow small groups of people to collaboratively explore high resolution imagery or large amounts of data. Read more about high resolution applications.

The VisWall product is a large and seamless high resolution display that is achieved by the precise alignment of many separate projectors that all rear-project onto one large screen. The VisBlock product is a borderless and stackable projection cube with one projector and one rigid screen per block. Groups of VisBlocks can be arranged to form large high resolution displays with virtually no borders between blocks. The VisWall-LCD is a high resolution display made up of many flat panels, resulting in a very shallow display but with significant borders between tiles due to the panel bezels. The tradeoffs between these 3 products are illustrated below.

VisWall, VisBlock	VisWall-LCD
Seamless	Discontinuity	OR	Hidden Pixels
All of imagery is visible and there are no discontinuities.	All of imagery is visible but spatial relationships are not preserved.		Spatial relationships are preserved but parts of imagery are hidden.

The table above illustrates the effect of the bezels in the VisWall-LCD using two different approaches for displaying imagery across the borders. For some applications, discontinuity is not much of an issue. For others, hidden pixels are acceptable. However, for many applications the data is continuous and spatial relationships are important for perceptualizing the data. In these cases the borders of the VisWall-LCD can be very distracting and interfere with proper visualization.

The table below highlights the key differences between the VisWall, VisBlock, and VisWall-LCD products.
