Abstract
A method for displaying images on multiple monitors with different refresh rates is disclosed. To prevent screen tearing, the surface containing image data is not released when the access by the master monitor is completed until the slave monitor or monitors finish access. To synchronize images with a predefined playback speed, the surface containing a new image received from the application is not flipped onto the screens until receiving a predefined synchronization indicator.
