Device Operation
EDID Management
Before a source can send picture and sound to a display device, the source reads the EDID (Extended Display
Identication Data) stored in the display. The EDID contains information about what type of video and audio formats
are supported by the display. The AT-OME-MH21 can use either the downstream EDID (from the display/sink) or use
a built-in EDID preset. Custom EDID data can also be stored in a user-dened preset. This section will cover each of
the following topics:
• EDID Presets
• Using the Downstream EDID
• Storing EDID Data
By default, the AT-OME-MH21 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

2. Click EDID in the menu bar.
3. Locate the EDID Settings section.

Displays.
