In one embodiment, a delay circuit is configured to delay pixel information from an image source, such as a frame buffer. The delay circuit may be configured to delay the pixel information by an amount of time that would move a pixel projected on a surface by a distance less than a dimension of the pixel. A light modulator may modulate a light beam onto a surface, such as a display screen, based on the delayed pixel information. This advantageously allows for sub-pixel electronic alignment.
