==Mounting== Computer monitors are provided with a variety of methods for mounting them depending on the application and environment. ===Desktop=== A desktop monitor is typically provided with a stand from the manufacturer which lifts the monitor up to a more ergonomic viewing height. The stand may be attached to the monitor using a proprietary method or may use, or be adaptable to, a VESA mount. A VESA standard mount allows the monitor to be used with more after-market stands if the original stand is removed. Stands may be fixed or offer a variety of features such as height adjustment, horizontal swivel, and landscape or portrait screen orientation. ===VESA mount=== {{Main|Flat Display Mounting Interface}} [[File:Monitor arm stand (1).jpg|thumb|Hydraulic arm monitor stand, connected via VESA mount holes]] The Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as a VESA mount, is a family of standards defined by the Video Electronics Standards Association for mounting [[flat-panel display]]s to stands or wall mounts.<ref name="vesa-fdmi">{{cite web|title=FDMI Overview|url=http://www.vesa.org/wp-content/uploads/2010/12/FDMI-Overview.pdf|url-status=live|archive-url=https://web.archive.org/web/20110927035603/http://www.vesa.org/wp-content/uploads/2010/12/FDMI-Overview.pdf|archive-date=2011-09-27}}</ref> It is implemented on most modern flat-panel monitors and TVs. For computer monitors, the VESA Mount typically consists of four threaded holes on the rear of the display that will mate with an adapter bracket. ===Rack mount=== [[19-inch rack|Rack mount]] computer monitors are available in two styles and are intended to be mounted into a 19-inch rack: [[File:Rackmount-LCD.jpg|thumb|upright=1.0|A fixed {{convert|19|in|cm|adj=on}}, 4:3 rack mount LCD monitor]] ;Fixed A fixed rack mount monitor is mounted directly to the rack with the flat-panel or CRT visible at all times. The height of the unit is measured in rack units (RU) and 8U or 9U are most common to fit 17-inch or 19-inch screens. The front sides of the unit are provided with flanges to mount to the rack, providing appropriately spaced holes or slots for the rack mounting screws. A 19-inch diagonal screen is the largest size that will fit within the rails of a 19-inch rack. Larger flat-panels may be accommodated but are 'mount-on-rack' and extend forward of the rack. There are smaller display units, typically used in broadcast environments, which fit multiple smaller screens side by side into one rack mount. [[File:Rackmount-KVM.jpg|thumb|upright=1.0|A 1U stowable clamshell {{convert|19|in|cm|adj=on}}, 4:3 rack mount LCD monitor with keyboard]] ;Stowable A stowable rack mount monitor is [[rack unit|1U, 2U or 3U]] high and is mounted on [[Linear-motion bearing|rack slides]] allowing the display to be folded down and the unit slid into the rack for storage as a [[drawer]]. The flat display is visible only when pulled out of the rack and deployed. These units may include only a display or may be equipped with a keyboard creating a [[Rackmount KVM|KVM]] (Keyboard Video Monitor). Most common are systems with a single LCD but there are systems providing two or three displays in a single rack mount system. [[File:Panel-Mount-LCD.jpg|thumb|upright=1.0|A panel mount {{convert|19|in|cm|adj=on}}, 4:3 rack mount LCD monitor]] ===Panel mount=== A panel mount computer monitor is intended for mounting into a flat surface with the front of the display unit protruding just slightly. They may also be mounted to the rear of the panel. A flange is provided around the screen, sides, top and bottom, to allow mounting. This contrasts with a rack mount display where the flanges are only on the sides. The flanges will be provided with holes for thru-bolts or may have studs welded to the rear surface to secure the unit in the hole in the panel. Often a gasket is provided to provide a water-tight seal to the panel and the front of the screen will be sealed to the back of the front panel to prevent water and dirt contamination. ===Open frame=== An open frame monitor provides the display and enough supporting structure to hold associated electronics and to minimally support the display. Provision will be made for attaching the unit to some external structure for support and protection. Open frame monitors are intended to be built into some other piece of equipment providing its own case. An arcade video game would be a good example with the display mounted inside the cabinet. There is usually an open frame display inside all end-use displays with the end-use display simply providing an attractive protective enclosure. Some rack mount monitor manufacturers will purchase desktop displays, take them apart, and discard the outer plastic parts, keeping the inner open-frame display for inclusion into their product.
