Image-based remote access systems and methods are described herein. At least some illustrative embodiments include a method that includes dividing into a plurality of sub-regions graphical data in a first frame buffer (402) associated with a graphics adapter (each of the sub-regions uniquely associated with one of a plurality of displays, and each location within the frame buffer including pixel data to be presented on a display), generating difference data (404) by comparing data in a second frame buffer (also associated with the graphics adapter and including previously presented display data) with the data in the first frame buffer, and transmitting within a message at least part of the difference data (410) across a network to a client device that includes the plurality of displays (the message including difference data associated with a sub-region (406), and a sub-region identifier). The difference data is usable to update an image on the plurality of displays.
