A computational device divides, by a seam, a screen into first and second logical displays; in a first mode, moves the seam to a first position to provide logical displays having different selected aspect ratios, viewing angles, and/or a viewable image sizes and, in a second mode, moves the seam to a second different position to provide logical displays having still different selected aspect ratios, viewing angles, and/or a viewable image sizes.
