Abstract: A method and apparatus are provided for enabling application program compatibility with display devices having an increased pixel density. According to one method, a call including one or more parameters is directed toward an application programming interface for performing a screen input or output function is received from an application program. In response to receiving the call, a determination is made as to whether the application program is configured for use with a display device having a lower pixel density or a display device having a higher pixel density. In response to determining that the application program is configured for use with a display device having a lower pixel density, the parameters are scaled for the higher pixel density display device and the application programming interface is called using the scaled parameters.
