EDID CONFIGURATION TYPES
There are 3 types of modes when display devices are attached or removed.
To enable these modes for all channels, simply type one of the following: ‘auto’, ‘lock’ or ‘gcm’.
The HotPlugDetect (HPD) signal is the signal that indicates to the OS if a device is plugged in or not.
1
‘Enable’ means that HPD indicates to the OS its detected, and the device will show up in display manager.
2
‘Disable’ means that HPD indicates to the OS its not-detected, the display will NOT show in display manager.
3
‘EDID’ is the detailed information about the display device that is typically read when a display is plugged in, and
every time the system boots. This data is provided to the OS Display Manager, and is used by the OS to set the
resolution, refresh-rate and color capabilities of the display device.
PURPOSE OF THE EDID OPERATING MODES
Many of the problems that arise in display systems stem from display devices being connected and
disconnected. This can happen when cables or displays are physically connected/disconnected, or
when display power is turned on/o
ff
. The time that it takes for each display to be detected may vary,
which causes all kinds of problems with screen order, screen resolution settings, desktop configuration in
multi-desktop configurations, and especially when configuring AMD
TM
Eyefinity Display Groups or
NVIDIA
TM
Mosaic.
All advoli
TM
graphics cards solve this problem by a patented technology that presents the EDID
information from EEPROMS on the physical hardware rather than directly from the display devices
themselves. This means that the correct data is presented to the Operating System on every boot, and
every time the OS requests the data immediately and without delay.
With advoli
TM
graphics cards you can configure screens and EDID data, either automatically or manually,
exactly the way you want it and then ‘lock’ the configuration with a simple command, and your
configuration will never change even if screens are physically unplugged or changed.
