Chapter 3. EDID Management
1. EDID settings
EDID stands for Extended Display Identification Data.
EDID is an industry standard for AV Source and Display devices which automatically communicates
manufacturer specification and data between devices.
This allows your AV source to send the best compatible signal data to your screen, TV, or projector
to ensure the best possible picture results.
EDID data includes manufacturer and specification data including:
• Brand
• Product Code
• Date of Manufacture
• Video Input Type
• Horizontal and Vertical Size
• Supported features
•Color characteristics
• Timing information
