Abstract:
1. A method for selecting a display timing to use in displaying information from an electronic device on an external display that is coupled to the electronic device over a communications link, comprising: with control circuitry in the electronic device, obtaining information on the capabilities of the external display over the communications link, wherein the obtained information on the capabilities of the external display includes timing elements; scoring the timing elements using a scoring function implemented on the control circuitry, wherein scoring the timing elements comprises: computing initial scores for the timing elements based on a horizontal active pixel count, a vertical active pixel count, and a refresh rate; incrementing the initial scores of the timing elements by a first amount based on a first increment criteria; and incrementing the initial scores by a second amount based on a second increment criteria that is different than the first increment criteria, wherein the first amount is different than the second amount; sorting the scored timing elements based on the incremented scores to create a sorted list of timing elements; with the control circuitry, selecting and using one of the scored timing elements in the sorted list to display information on the external display.
