Computer display apparatus

A display controller comprising:

• a display processor programmed to generate pixel data according to imaging instructions;
• a display re-mapper operatively coupled to the display processor and programmed to manipulate the pixel data according to display mode instructions;
• a first and second refresh output operatively coupled to the display re-mapper, the first refresh output being programmed to generate an image display from at least part of the manipulated pixel data on a first display unit in a first display mode and the second refresh output being programmed to generate an image display from at least part of the manipulated pixel data on a second display unit in a second display mode,
• wherein the image displayed on the first display unit is displayed in a display mode independent of the display mode of the image displayed on the second display unit.

A display controller comprising:

• a display processor programmed to generate pixel data according to imaging instructions;
• a first and second refresh output, the first refresh output being programmed to request pixel data for a first display unit and a second refresh output being programmed to request pixel data for a second display unit;
• a display memory fetcher operatively coupled to the display processor and the first and second refresh outputs, wherein the display memory fetcher is programmed to manipulate pixel data according to display mode instructions in response to a request for pixel data from at least one of the first and second refresh outputs,
• wherein the requesting refresh output is programmed to generate an image display on a display unit from the manipulated pixel data in accordance with display mode instructions and an image displayed on the first display unit is displayed in a display mode independent of the display mode of the image displayed on the second display unit.
