4.1. ADC Adjustment
4.1.1. Overview
▪ ADC adjustment is needed to find the optimum black level
and gain in Analog-to-Digital device and to compensate RGB
deviation.
▪ ADC adjustment is OTP (Auto ADC)
4.2. EDID Download
4.2.1. Overview
▪ It is a VESA regulation. A PC or a MNT will display an
optimal resolution through information sharing without any
necessity of user input. It is a realization of “Plug and Play”.
4.2.2. Equipment
(1) Since EDID data is embedded, EDID download JIG, HDMI
cable is not need.
(2) Adjust by using remote controller
4.2.3. Download method (using DFT)
※
PC(for communication through RS-232C), UART baud rate:
115200 bps
Command : aa 00 00 (Start Factory mode)
Command : ae 00 10 (Download All EDID)
Command : aa 00 90 (End of Factory mode)
