EDID Minder
The SW2 DP switchers utilize the EDID Minder, which maintains EDID communication to all
connected source devices, whether or not the source is selected. EDID information consists
of the display resolution, refresh rate, data rate, supported audio formats, and other
features. By factory default, the stored EDID contains information for a native resolution of
1920x1080 @ 60 Hz with 2-channel audio.
During power up, the source devices use an auxiliary channel to obtain Extended Display
Identification Data (EDID) from the display device. This allows the output signal to match the
resolution and refresh rate of the display device.
NOTES:
EDID information is read from the display device connected to the output. The learned EDID
is stored in memory and is retained after a power cycle or after a new display device is
connected to the output. A reset to factory values returns the EDID to the default.
The new EDID is then available when DIP switch 1 is in the Stored (down) position. Each
time a new EDID is recorded, it overwrites the existing data and is available when DIP switch
1 in the Stored position.

The EDID Minder LED lights amber, then changes to green when the recording process is
successfully completed.
Changing the stored EDID
To replace the stored EDID with that of a different display, connect the new display to
the output, then repeat steps 2 through 4 of the
described above.
EDID Minder DIP switch settings
The EDID Minder DIP switch (DIP switch 1, on the left) selects the EDID value that is
presented to the source device:
•
•
When the DIP switch is in this position, press the EDID button to initiate EDID storing.
NOTE: DIP switch 2, on the right, is not used.
•
The SW2 DP is fully HDCP compliant. The source negotiates with the SW2 DP
input and the display negotiates with the SW2 DP output.
•
The SW2 DP does not support DisplayPort Content Protection (DPCP).
•
The SW2 DP assigns identical EDIDs to the inputs.
Connect the display device that will provide EDID information to the output.
Power on the display and the SW2 DP.
Set DIP switch 1 in the Stored (down) position (see
for more information about setting the DIP switches).
Using a stylus or small Philips screwdriver, press the recessed EDID Store button.
In the Default (up) position, the EDID value is the factory-stored default, with a
resolution of 1920x1080 @ 60 Hz with 2-channel audio.
In the Stored (down) position, the most recently recorded EDID value is used (this file
overwrites previously stored values). Before any other EDID file is recorded, this is also
the factory default resolution of 1920x1080 @ 60 Hz with 2-channel audio.
