Welcome!
Congratulations on your purchase of the PureLink SE-DDL Smart EDID Dual link DVI EDID emulator and
equalizer.
This manual contains information that will assist you in installing and operating the product.
1.2 Product Description
SE-DDL is a Dual link DVI EDID emulator that is designed for single-link and dual-link DVI devices,
enables you to emulate and store EDID (Extended Display Identification Data) information from the
display.
SE-DDL can trick the DVI source (PC computer, Laptop, etc) emulating any DVI display (LCD monitor,
projector) for continuous video output, even if the attached display is disconnected, or powered down.
Emulating EDID, the user can set up any DVI output resolution, regardless of the used projector or
monitor, this way the overall system
’s resolution can be controlled.
There are many video peripheral devices which do not offer EDID handshake between the source and
remote location displays, the SE-DDL is a perfect solution for ensuring the optimum signal is provided to
the display to help prolong the life of the displays.

EDID
) is an information set that digital display provides to describe
its capabilities to a Video source. Video source will know what kinds of displays are connected and it will
determine which resolution to Output according to the EDID information received from the display.
The EDID normally includes manufacturer name and serial number, sets of capable resolution including
native resolution, supported timing, pixel mapping data (for digital displays only) and etc.
In a digital connectivity environment; in order to support the maximum resolution of connected monitor,
EDID handshake is a critical because improper EDID handshake between sources to the display will
result in no image on the display.
EDID handshake may sound simple; however, with multiple peripheral devices within the chain, display's
EDID information easily get lost or blocked while it is traveling to the source device.
