VESA Standard lOOmm TV Mounts and Stands
Following are shown some examples of VESA standard 100 mm mounts. Since there are numerous types of
stands and mounts available, only a few are shown here. Refer to the instructions provided with the TV
stand that will be used to mount the TV.

Generat Guidetines: Choosing a tocation for
instatting a VESA Standard Mount Typicat Pedestat Type Mount with Swive[ Bracket
Be sure the style of stand selected is capable of supporting
the weight of the TV.
If the mount wilt be on a walt, a typical wooden stud behind
the watt board would be the preferred choice for a location
to attach the watt mount. The watt mount location chosen
should be appro-priate for drilling holes and have available
the required power source as welt as antenna/cable and
other equipment leads.
For pedestal-type mounts, a sturdy surface on a desk or
other similar flat table-like surface would be the appropriate
location for mounting a pedestal-style TVstand. (Some
stands are portable and can be moved from one location to
another.) Be sure all safety considerations are followed.
Most stands are designed so that the wiring would be
threaded through the stand itself or a loop-through style
clamp so that the wiring is neatly bunched and not strung in
such a way as to create a potential hazard to the user.
