A video module for a video wall, comprising an assembly of multiple video display units whose front edges are abutting and are all in the same plane as a rectangular array, and a common box-shaped enclosure for the assembly. The image shown on the display units is switchable between modes, appearing as several identical images or else as just one, larger, image. A cathode ray tube is also disclosed with corner mounting lugs specially formed such that their edges do not project beyond the tangents from the major edges of the screen. A sleeve for a cathode ray tube is also disclosed, in the form of an open ended rigid box with formations on the inside of the corners for fixture to corner lugs of the cathode ray tube: the side walls of the box are partially broken away at the front edges to allow the edges of the cathode ray tubes supported therein to touch one another. |
