Edid Minder - Extron electronics DTP T SW4 HD 4K User Manual

EDID Minder

The DTP T SW4 HD 4K switcher uses EDID Minder, which ensures that a source device
connected to the HDMI input continuously sees the EDID of a sink device, even after the
sink is disconnected.
By default, the EDID is set to 1080p @ 60 Hz with 2-channel audio (slot 11).
Additional available values are shown in the table below. There are 12 factory-loaded EDIDs,
one slot is automatically populated by EDID from a connected sink device, and two slots
can be manually populated with EDID imported by the user.

* Default EDID
Factory EDID Slots
Factory EDID is available for most common resolutions and audio formats.
Output Slot
This slot contains the EDID of the connected sink device. When HPD is detected, the EDID
of the sink device is stored automatically.
When a sink is removed or power to the switcher is cycled, the EDID is removed from the
slot and replaced with the default value until a sink is detected and the EDID stored.
User Slots
These two slots are available for storing imported EDID files. Initially, these slots contain the
default EDID until they are overwritten by the imported files. The imported files remain in the
slots until they are overwritten or the unit is reset.
EDID Memory Retention
The assigned EDID is stored to an EEPROM, which is located at the HDMI input. The stored
EDID is retained until a reset is initiated.
Hot Plug Detect (HPD)
HPD remains high on all inputs while the unit is powered on. The HPD drops low only while
EDID is updated.
