1:1 pixel mapping is a video display technique applicable to devices with native fixed pixels, such as LCD monitors and plasma displays. A monitor that has been set to 1:1 pixel mapping will display an input source without scaling it, such that each pixel received is mapped to a single native pixel on the monitor. This technique avoids loss of sharpness due to scaling artifacts and normally{{Efn|Except the uncommon case where display and input differ in pixel aspect ratio such as when one doesn't use square pixels}} avoids incorrect aspect ratio due to stretching. If the input resolution is less than the monitor's native resolution, this will result in black borders around the image (e.g. letterboxing or windowboxing).{{cite web|last1=Sayer|first1=Rob|title=Guide to Pixel Mapping|url=http://www.onstagelighting.co.uk/lighting-equipment/stage-lighting-control/guide-to-pixel-mapping/|website=onstagelighting.co.uk|accessdate=18 June 2015|date=17 February 2009}}{{cite web|url=https://www.engadget.com/2007/08/20/does-your-hdtv-support-1-1-pixel-mapping/|title=Does your HDTV support 1:1 pixel mapping?|last1=Drawbaugh|first1=Ben|date=20 August 2007|website=Engadget|url-status=live|archive-url=https://web.archive.org/web/20111008153055/http://www.engadget.com:80/2007/08/20/does-your-hdtv-support-1-1-pixel-mapping/ |archive-date=2011-10-08 |accessdate=18 June 2015}}
