Video Display Mounting Systems
Aug 1, 2003 12:00 PM, Bennett Liles
The only part of the video display market that offers a more potentially bewildering choice of types and styles than the displays themselves is the area of mounting systems.
Due to the sheer number of makes, models, and applications, any choice must be made with some serious and detailed planning. If the selection of a display type and size has been made, often there will be more than one type of mount that can work for the location, and the selection will depend on the intended use. Mounting systems are available from display dealers as well as directly from the firms that specialize in the mounts. At the time of purchase, the local dealer should have a range of mounts in stock appropriate for each make and model carried or the dealer should be able to order a mounting system appropriate for the planned use. If you decide to shop for a mounting system on your own, there is a wide selection available from display mount manufacturers. They are also a rich source of information about which mount is appropriate for the type, make, and model display, and they can offer advice about installation. Some dealer Web sites have an online questionnaire that will enable you to quickly narrow the selection of mounts for your chosen video display.
Most of the available wall and ceiling systems include a bracket for the mounting surface and a bracket that attaches to the back or side of the display. These brackets may be connected directly to each other or separated by a pole or articulated arm for pivot and swivel mounting. Most also include some type of lever or latch that provides for a quick and easy joining and separation of the display bracket and surface bracket. Included with many polemount systems is a kit with plates to cover the pole ends and the mounting hardware. Most floor-to-ceiling polemounts can also be ordered with an assortment of attachable shelves for VCRs and DVD units. Internal cable concealment is provided, and there are even decorative plates in a range of colors and patterns that can be slid into slotted fronts on some mounts to better match the room decor.
Among desk-, wall-, and ceilingmount systems is a variety of moveable arms to join the display and surface brackets. These may have from one to three pivot points affording a wide range of positions for the display. The larger, heavier displays may require a mount with a gas-filled cylinder in the arm for better support and ease of movement. That feature is widely known as a gas spring or gas assist.
MOUNT UP — CAREFULLY
Once the proper mount for the application has been selected, the installation process follows. In this phase, careful planning can avoid a catastrophe. Some walls and ceilings will require substantial reinforcement before the mount and the display it holds can function properly and safely. Many mounting system specifications require that ceilings or walls be able to support at least five times the combined weight of the display and mount. A range of mounting brackets and additional hardware is available to suit the shape and type of material supporting the display screen.
Professional installers, called in after a do-it-yourself disaster, frequently find that mounting bolts have only partially penetrated studs or missed them entirely or that overtightened bolts have begun to tear out the supporting material. Another problem frequently found is one in which surface and display device brackets have been improperly attached to each other. In some cases, it's as simple as a latch that was never engaged. Often discovered is inappropriate mounting hardware for the surface used. Screws and bolts must be chosen specifically for wood stud, metal stud, or concrete surfaces. Inset wallmounts may also require proper ventilation, particularly for deep, hot-running CRTs. Some manufacturers offer small fans as an option for wall installations with recessed CRT or plasma screens. In the more exacting specifications such as the spacing of bolt holes, there are some common guidelines.
VESA FDMI STANDARD
One term that will frequently appear in video display system mounting specs is the Video Electronics Standards Association's Flat Display Mounting Interface (VESA FDMI) standard. In the world of flat-panel displays, the VESA FDMI standard will dictate several display mounting parameters. Among those are cable and power supply locations and the exact mounting bolt hole pattern the display will have. VESA, a group of more than 300 member companies involved in electronics manufacturing, and its FDMI guidelines supercede the older Flat Panel Monitor Physical Mounting Interface standard, originally published in 1997.
The specific objectives of the VESA FDMI standard involve defining a set of mounting interface guidelines for a wide variety of flat displays having a diagonal viewing area from 4 inches up to 90 inches. The standard is intended to specify options including desktop, wall, overhead, mobile, and specialty mounting applications. Also defined are interface mounting pads, wallmount brackets, and other mounting devices supplied by the various manufacturers. These include center and edgemount guidelines.
The standard consists of two primary parts. The VESA MIS-D, C 100/75 is the most common, and it specifies a 75-by-75 mm or 100-by-100 mm mounting hole pattern. The VESA MIS-E, C calls for a mounting pattern that measures 100 by 200 mm. Plates to adapt one mount to the other are available. If your display does not conform to the standard, the manufacturer should be able to supply adapter plates to interface its product with one of the VESA standard choices. Most often the wider spread of the MESA MIS-E will be specified for larger and heavier displays. The VESA FDMI standard has made the selection of video display mounts much cheaper and easier for buyers, and it has given manufacturers a uniform guideline to assist their marketing efforts.
Heading up the stable of video display mount manufacturers is Lucasey Manufacturing. Nearly as old as video itself, the company's expertise in mounting systems goes back to 1949. Lucasey offers interchangeable designs to meet a huge range of possibilities in display mounting situations, and each mount is tested to four times the published maximum load limit. For CRTs up to 500 pounds, the Atlas ceilingmounts feature an adjustable yoke to fit 30- to 45-inch monitors and patented squeeze arms for a secure fit on large TVs. Smaller ceilingmounts have swiveling trays, and for going in the opposite direction, there are countertop pedestal mounts such as the P 10 Series with a 90-degree swivel and a -15- to +15-degree adjustable or fixed tilt. Also offered are locking swivelmounts, slide-out models, and multiple-monitor ring and in-line mounts. Lucasey's double- and single-stud wallmounts can fit a wide range of monitor sizes, and their Weather Safe wall- and ceilingmounts can protect CRTs under a variety of harsh weather conditions.
Also available are lockable VCR and cable boxes. The VSOO locking TV/VCR stackermount can put a TV and VCR in the same unit with a single lock and features a 360-degree horizontal swivel. One especially interesting Lucasey product is the CMAH one-person, 500-pound ACM hoist system. With this portable tool, a single operator can easily hoist a 500-pound display up to 18 feet. Lucasey also carries a huge assortment of wall- and ceilingmount accessories and a wide selection of mounts for flat-panel displays.
