A display system comprises a wall of video screens each driven by a respective video driver (24A-24D). Information to be displayed is supplied from a host computer (10) having conventional input/output devices (12, 14). Each circuit board of the host computer serves a number of video channels and supplies the information to be displayed on each screen to an associated portion of random access memory (22A to 22E). Thus, each screen displays a portion of an image or the whole image when the video drivers read out data in parallel from the portions of memory (22A to 22E). The information displayed may be altered via the input devices (12, 14) to the host computer (10). |
