Abstract
A method is provided for indicating to a user that a sink device is incorrectly connected to a High Definition Multimedia Interface (HDMI) In port. In accordance with the method, a proxy voltage is applied from an HDMI In port over an HDMI cable. The proxy voltage is sufficient to cause a hot plug event to occur. A hot plug event condition is detected at the HDMI In port from a device that is connected to the HDMI In port via the HDMI cable. Extended Display Identification Data (EDID) is read from the device at the HDMI In port over the HDMI cable. In response to receipt of the EDID, a determination is made that the device is a sink device and an error message is generated in response to the determination.
