The present invention relates to development of software for adjusting a screen without latency to suit the type and shape of a screen when an image is projected by a projector and, more specifically, to software for remotely controlling and performing a technique for adjusting the size and shape of a screen, controlling the brightness of an overlapping portion between two or more screens, and blacking unnecessary portions through a network in the form of software without latency. The software of the present invention adjusts a screen using wasted waiting time unlike the prior art of waiting until a next frame is sent to a graphic card after the current frame is completely rendered by the graphic card. The software stores information on frames in a front buffer, switches the front buffer to a back buffer in addition to vertical synchronization, reads a buffer in front of a next frame in advance, and processes screen adjustment, thereby completing all processes using the time when a previous frame is switched to a next frame. Therefore, the software requires no time added to process screen adjustment, thereby being driven without latency.
