Abstract
The disclosed embodiments provide a system that drives a first display and a second display with a higher pixel density than the first display from a computer system. During operation, the system provides a set of backing stores for windows in the computer system. Next, the system enables a first set of clients to draw to the backing stores using a virtual coordinate system. Finally, the system uses the backing stores to drive the first and second displays so that a given distance in the virtual coordinate system is substantially the same size on the first and second displays.
