1. A term used to describe the process of turning on and leaving on an electronic device for a pre-determined length of time to help prevent any premature failures. Often a computer or other electronics manufacturer will have some type of burn in before shipping a device to help detect and prevent failures.
- Software burn-in utilities as well as motherboard diagnostic utilities can be found on document CH001089.
2. Also known as a ghost a burn in is a term used to describe an issue that occurs when a computer monitor is left on for long periods of time with one static or non-moving image causing that image to be burned into the phosphors of the monitor. When this issue occurs you will notice a ghost image of the static image whenever the monitor is on. This issue occurred frequently with older with older CGA / EGA CRT monitors and is still possible for new CRT monitors to also encounter this issue (although not as common). To help prevent this issue turn off the monitor or use a screen saver whenever you're not using the monitor. If this issue has occurred on your monitor you can try degaussing the monitor. Unfortunately a burn in is often permanent and will never fully disappear from the monitor.
