Taking RGB Input from PC for Leon3 on Basys3 with PMOD to VGA Converter

Hello everyone,

I’ve implemented the Leon3 configuration on the Basys3 board and discovered that the built-in VGA port on the Basys3 acts as an output-only (drive) port. To solve this, I purchased a PMOD to VGA converter, but I realized that it also functions as an output drive.

I want to take RGB input from my PC (to process or display through the Basys3). However, it seems both the built-in VGA port and the PMOD VGA converter are output-only.

Does anyone have any advice or suggestions on how I can take RGB input from my PC via VGA on the Basys3? Any guidance or experience would be much appreciated!
