Device Operation
EDID Management
Before a source can send picture and sound to a display device, the source reads the EDID (Extended Display
Identification Data) stored in the display. The EDID contains information about what type of video and audio formats
are supported by the display. The AT-HDR-SW-51 can use either the downstream EDID (from the display/sink) or use
a built-in EDID preset. EDID data can also be stored in any of eight EDID presets. This section will cover each of the
following topics:
• Using the Downstream EDID
•
EDID Presets
• Storing EDID Data
By default, the AT-HDR-SW-51 will read the EDID from the display device. The term “downstream” is used to
describe any device that receives a signal from another device. For example, if a Blu-ray player is connected to a
display, the display is said to be “downstream” of the Blu-ray player.
Using the Downstream EDID
1. Log in to the web server.
2. Click
EDID
in the menu bar.
3. Locate the
EDID Settings
section.
4. Click the drop-down list, next to the input that is connected to the source device, and select
Connected
Display
. For example, if
HDMI IN 1
is connected to a source, click the
Input 1
drop-down list and select
Connected Display
. The source device will read the EDID of the connected display and determine all
supported video and audio formats.
