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 display drivers of the devices you attach (graphics cards for example) to match perfectly with the screen. 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.
What is DDC EDID?
DDC EDID is the data that describes the characteristics 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 in 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.
