APx500 supports EDID and E-EDID for HDMI.
EDID (Extended Display Identification Data) and E-EDID (Enhanced Extended Display Identification Data) are data stored in downstream (sink) devices and communicated to upstream (source) devices. The HDMI transport stream can carry EDID metadata.
EDID contains information about the downstream device, including its video and audio capabilities so that the source device can format the content properly. This means, for example, that a downstream 720x480p video monitor with only two audio channels will cause an upstream surround decoder or Blu-ray player to provide a 720x480p video signal with a stereo downmix when connected to this device.
EDID is defined by a standard published by the Video Electronics Standards Association (VESA).
