My computer connects to the monitor using a VGA cable. I want to turn the display grayscale or black & white.
I don't want to use any software solutions as I fear it will not be as effective as I want it to be.
So I researched the Internet for RFC of VGA pin and cable and I couldn't find such an RFC and pin layout configuration was not helpful.
Is there a way I can build a mod which I can attach to either the output of the computer or to the input of the monitor, which discards the color information and display either a grayscale image or black & white image? If possible I would also like the mod to throttle the refresh rate to either 24Hz or 30Hz.
It has to display a resolution of 1920 x 1080.
