DDC Ghost

The Adder DDC Ghost has been developed to allow you to extend the life of your existing systems by adding full EDID data to your VGA signals

The Adder DDC Ghost is the most cost effective way to extend the life of your existing infrastructure. EDID data is a very important part of video extension and distribution, it allows the screens you use to match perfectly with the display drivers of the devices you attach to (graphics cards for example).  The DDC (Display Data Channel) carries information about the physical characteristics of the screen, such as resolution or colour depth, back to the display adapter (graphics gard) to ensure the resulting picture is correct, every time.

Full EDID Cloning
The DDC Ghost will clone a full dual page EDID (Extended Display Identification Data). This makes the DDC Ghost compatible with the latest ranges of display devices.  The first page is the standard EDID data, and the second covers the extended data block. Standard EDID DataOur expertise with DDC EDID data has allowed us to put together an extended profile which is designed to cover most display devices. As such, the DDC Ghost may be used  in connections where no data is otherwise available. You can choose whether to use this data or the original screen EDID attached.

Push and Go Setup
The DDC Ghost interface is secure and simple. Setting up the device is a single button process directed by the inbuilt LED indicator.  This makes characteristics changing display devices a fast and simple process

What is DDC EDID?
DDC EDID is the data that describes the of the display device (monitor) to the display adapter
(graphics card). This data is what enables plug and play connection with monitors. Characteristics included in the EDID data include: supported resolutions, manufacturer, phosphor/filter type, display size, luninance data and in the case of digital panels - pixel mapping.The DDC EDID is stored by the monitor, and requested by the graphics card. When you put a device in between the  two, you need to ensure the DDC EDID is still passed through. In cases where the DDC EDID is not passed, DDC Ghost sits inline and provides the data directly to the graphics card. Essentially, the monitor is no longer asked for DDC EDID.

FEATURES

True DDC Emulation
Unless an extender actively supports DDC, some high performance video cards cannot be used at high resolutions. The DDC Ghost supports dual page DDC ensuring compatible resolutions are supported.

Interface Powered
The  DDC Ghost takes its power directly from VGA pin 9. This reduces clutter, and makes installation as simple as possible. In situations where no pin 9 power is available, DDC Ghost can be powered directly via the optional 5V power supply.
