Taking our 12.5% overlap region, this equates to 160 pixels with our SXGA projectors (1280 x 0.125 = 160 pixels). In the example described, the total available resolution of the three projectors titled horizontally before overlapping is: In this example we use a 12.5% region because existing resolutions result in whole pixels: However, because of different projector resolutions, it is good to standardize on the same overlapping region. Note: It is good to have a complete number of pixels and the same physical screen size when edge blending. Figure 1: Example overlapping regions of 3 SXGA displays. Each projector has a resolution of 1280×1024 (SXGA). Modify the software application to have the same calculated overlap region.Īs an example, here we present overlapping regions based upon a three projector setup.Align the projectors to the calculated overlap.Three steps are required in order to produce an overlap region: In this overlapping area, edge blending is later applied.

Before edge blending can occur, the projectors and software application need to be set-up so that an overlapping region between the edges of adjacent projectors is present.
