    Hello friends,
    I would like to make a simple RGB
    LED display panel and drive it with the output of the VGA port on my pc so that I can display information on the pc screen onto the LED display
    panel. I've just learned the pin definitions of the relevant vga port: Pin 1: Red video data
    Pin 2: Green video data
    Pin 3: Blue video data
    Pins 6,7,8: Red, Green and Blue groundings
    Pin 13: Horizontal sync
    Pin 14: Vertical sync .
    My problem is how to drive the 307,200 (640×480) pixels with the single RGB LEDs from the vga port and combining it with the vertical
    and horizontal syncs. I need help on relevant circuits, ICs (registers, multiplexers, encoders etc...)
    Data output of the VGA port are analogue signals.
    Thank you.
