The 4x1 HD Switcher w/ Audio Decoding has three EDID modes (INT, EXT, and MIX).
• INT Mode
The internal (local) EDID is used instead of the EDID from the display device. EDID
features newer than HDMI 1.3 are removed from the EDID data structure when the
display is read. This provides a general EDID which is compatible with more displays.
• EXT Mode
The external (downstream) EDID is used. In this mode, both DDC and HPD are
passed through and the 4x1 HD Switcher w/ Audio Decoding uses the full video
capabilities of the display. The HPD status will also be detected by the source device.
• MIX Mode
The display capabilities from the external EDID are combined with the audio
capabilities of the internal EDID of the 4x1 HD Switcher w/ Audio Decoding.
