Abstract
A method and system that configures an HDMI source device to use initial output parameters for communicating with an HDMI sink device, detects an abnormal operation performed by the HDMI sink device, selects a test of the HDMI sink device, applies the test, evaluates a result to determine whether the test produces a desired result, and modifies the initial output parameters to create revised output parameters. When the test produces the desired result, the revised output parameters will enable the HDMI sink device to produce the desired result. When the test fails to produce the desired result, the revised output parameters are conservative parameters that fail to produce the abnormal operation. The method reconfigures the HDMI source device to use the revised output parameters for communicating with the HDMI sink device, and saves the revised output parameters.
