Automatic EDID Mode (digital output only)
In this mode, if no displays are connected, the default EDID (720p @ 60 Hz, with
2-channel PCM audio support) is present as the native resolution at each HDMI input.
When a display is connected to the digital output, the EDID of that display is automatically
read and stored, and the default EDID is overwritten for each HDMI input. The reading and
storage of the new data is triggered by the Hot Plug Detect signal (HPD) the moment the
display is detected. The stored data remains present even after the display is removed.
When a display with a different EDID is connected, or a user assigned EDID is chosen, the
HDP triggers a new data overwrite for all the digital inputs.
NOTE: The Hot Plug Detect (HDP) signal triggers on all digital inputs simultaneously
whenever a stored EDID is updated regardless whether it is by an automatic or
user assigned EDID. This allows the source to restart the EDID read and verify
the HDCP authentication process.
User Assigned EDID Mode
In this mode the EDIDs can be chosen (by the user) from the table and can be assigned to
each input group (VGA and HDMI). Within this mode, the user EDID can be factory loaded
(
see EDID table on page 22 ) or user loaded. For user loaded EDIDs these can be either
analog or digital EDIDs.
User Loaded EDID – Analog
The EDID of a display connected to the local (VGA) Buffered Output connector ( see c on
page 9 ) can be read and stored to the analog User Loaded spaces 1 or 2 (SIS values 49
and 50, see figure 14). This analog output EDID can later be recalled as the user assigned
analog EDID for inputs 1through 3.
To save the analog output EDID information to the User 1 or User 2 location in the
EDID table:
1. Connect the display to the local analog output on the MLS 608 D Series switcher.
2. Start DSP Configurator, if it is not running already, and connect to the device in the
Live mode.
3. From the Tools menu, select Configure EDID to open the EDID Configuration
dialog box.

4. In the Save Analog Output to User Loaded IDs section, click the User 1 or
User 2 button. This saves the EDID information from the analog output to the
associated location (User 1 or User 2). The saved resolutions and refresh rates are
now available as User 1 and User 2 options in the Inputs 1-3 section.
