6.1 The EDID Feature
The
VM-8DVI-R
can operate with the factory default EDID, or with an EDID
that is acquired from one of the outputs either automatically or manually.
6.1.1
Defining EDID
The Extended Display Identification Data (EDID
1
) is a data-structure,
provided by a display, to describe its capabilities to a graphics card (that is
connected to the display
's
source). The EDID enables the
VM-8DVI-R
to
“know” what kind of monitor is connected to the output. The EDID includes
the manufacturer’s name, the product type, the phosphor or filter type, the
timing data supported by the display, the display size, luminance data and (for
digital displays only) the pixel mapping data.
6.1.2
Acquiring the EDID
The EDID is acquired every time you turn the machine ON. You can either
acquire the EDID automatically or manually from one of the connected
outputs, or work with the default EDID.
6.1.2.1 Acquiring or Restoring the Factory Default EDID
To select an EDID:
1. Disconnect all the outputs.
2. Turn OFF the power on the
VM-8DVI-R
and then turn it ON again.
If there are no outputs connected to the
VM-8DVI-R
, the factory default EDID
is acquired once the machine is turned ON
1 EDID is defined by a standard published by the Video Electronics Standards Association (VESA)
