| + | ======Objective====== | ||
| + | The objective of this project is to set up the hardware required to create a video wall, that is a tiled display, and then install the software that causes it to function as a video wall. | ||
| + | ======Materials/ | ||
| + | To do this project, you will need to have successfully completed: | ||
| + | * Linux/*BSD Desktop Install | ||
| + | \\ | ||
| + | You will need:\\ | ||
| + | * at least 2 computers (with a basic Linux install, Debian tends to stay out of your way more than Ubuntu) | ||
| + | * each computer equipped with a dual-head video card | ||
| + | * four LCDs (two driven by each computer)arranged the LCds into a 2×2 matrix | ||
| + | |||
| + | ======Background====== | ||
| + | The concept of a Video Wall (better called “Tiled Display Wall”) is the perfect visual example of High-Performance Computing. Taking multiple independent units, each with a given ability, and allowing them to work together to create a new unit that is more capable than the sum of its parts can be an impressive feat.\\ | ||
| + | But, unlike doing so on a cluster, a tiled display wall can demonstrate these concepts to those not as familiar with such concepts. | ||
| + | |||
| + | |||
| + | ======Procedure====== | ||
| + | **Preparation for the installation**\\ | ||
| + | - Obtained two personal computers and four video monitors. | ||
| + | - Check each computer and make sure each has a suitable hard drive. | ||
| + | - Checked the computers for system memory. Each computer contained 512 megabytes of ram. | ||
| + | - Arrange the personal computers so that the front of one faces the front of the other. With the computers arranged this way, a video monitor could sit on top of each of them and the other two monitors could sit in front of them. With the video monitors arranged this way, they form a video wall. | ||
| + | - Connect power cords to each computer. | ||
| + | - Connect power cords to each video monitor. | ||
| + | - Connect video patch cables to the digital video port of each computer. | ||
| + | - Connect analog video cables from the ends of the patch cables to each monitor. | ||
| + | - Load operating system components on each computer. In order to load operating system components simultaneously, | ||
