===Output to displays===
Although many manufacturers claim very high numbers, [[plasma displays]], [[LCDliquid-crystal displaysdisplay]]s, and [[Cathode ray tube|CRT displays]] can deliver only a fraction of the contrast ratio found in the real world, and these are usually measured under ideal conditions.{{Citation needed|date=February 2015}} The simultaneous contrast of real content under normal viewing conditions is significantly lower.
 
Some increase in dynamic range in LCD monitors can be achieved by automatically reducing the backlight for dark scenes. For example, LG calls this technology "Digital Fine Contrast";<ref>[http://www.lge.com/about/press_release/detail/PRO%7CNEWS%5EPRE%7CMENU_20075_PRE%7CMENU.jhtml Digital Fine Contrast]</ref> Samsung describes it as "dynamic contrast ratio". Another technique is to have an array of brighter and darker LED backlights, for example with systems developed by BrightSide Technologies.<ref>[http://www.dolby.com/promo/hdr/technology.html BrightSide Technologies is now part of Dolby -] {{webarchive|url=https://web.archive.org/web/20070910145331/http://www.dolby.com/promo/hdr/technology.html |date=2007-09-10 }}</ref>
