Abstract
A method and apparatus are provided for the simultaneous display of different “viewing areas” on a computer video display monitor so that a user sees them as displayed at different resolutions. When a user selects a resolution for a viewing area different from the background resolution of the rest of the video display monitor, the background resolution of the display monitor is set as the highest resolution at which data is to be displayed. High-level graphics commands are intercepted by a multi-resolution system mimicking a display driver. High-level graphics commands are interpolated using a resolution conversion ratio. Modified high-level graphics commands are sent to the true display driver and an image is displayed at an apparent resolution lower than the background resolution. This enables a user to optimize the display of computer data depending on the program outputting that data and the user's requirements.
