I don't know much about neural networks, but do you want the image to be displayed on a screen or something? I have only worked with Cyclone II and VGA screens, using a video DAC. If you have any fancy screen controller, than I think you need to read in it's manuals. If you, as I, want to show an image on a VGA screen, using nothing but a suitable DAC, you have to control all synch signals and simply send out your grayscale value when the pixel counter passes your 20x20-pixel-window.
