►Technical Design and Operating Principle

Main Controller/Converter Chip: The core of the board is likely a dedicated digital video converter chip. This chip is responsible for decoding low-voltage differential signaling (LVDS) or other digital video formats from the motherboard and re-encoding it into analog RGB (red, green, and blue) signals.

Digital-to-Analog Converter (DAC): VGA signals are analog, so a high-quality DAC is required to convert digital pixel information into precise analog voltages, which directly determines the color accuracy and clarity of the output image.

Signal Amplifier and Conditioning Circuit: The converted analog signal is weak and requires amplification and conditioning by an operational amplifier to ensure that the signal remains stable and does not produce blur or jitter after being transmitted for several meters through the VGA cable.
