Intel researchers have developed Display as a Service (DaaS), wireless technology that enables a single screen image to be shown on a wall of displays all working in unison, so that a piece of the original image is shown on each display.

Although that type of setup has been used for years at concerts and department stores, the displays all have to be connected with HDMI or DVI video cables. The Intel technology "virtualizes" the pixels on a display, separating them from the underlying hardware so that they can be sent via Wi-Fi and reassembled on other screens for viewing.

DaaS also can work in reverse, taking the displays from several laptops and showing them side by side on a single larger screen.

The technology uses the H.264 video compression standard to compress what is on a display so that it can be sent wirelessly to other screens. The software also includes metadata that tells the video how many screens it will be displayed on and how they are spaced relative to each other.
