A display interface connected between a computer and a CRT device processes predetermined blocks of display data from predetermined locations in a memory of the computer to form pixels having predetermined characteristics in the display fields of the CRT device. A CRT display format of parameters such as color, pixel shape and size, and field shape and size, is controlled by input FORMAT DATA. The display resolution can be varied to accommodate the amount of data to be displayed within the desired field dimensions. The display data is retrieved from memory in data blocks, each of which is identified by a BLOCK ADDRESS. A single data block may occupy the entire display field; or may be displayed in a subfield simultaneously with other data blocks, or portions of data blocks, in the remaining subfields. The FORMAT DATA determines the subfield number and arrangement.
