A TV Mount generally refers to a bracket made of metal that fixes to the rear of a TV flat display or screen.  Nearly every TV screen manufacturer arranges the screen fixing points in accordance with fixing hole patterns approved by the Video Electronics Standards Association (VESA), a US-based technical standards organisation.  These fixing orientations are arranged in a square or rectangle and are based on cardinal metric numbers, for instance, 100 x 100mm and 1000 x 600mm.  This means that TV Mounts can be designed to cover a number of VESA arrangements and thus become universal.<!-

There are many cabinets on the market that Audio Visual (AV) equipment can be stored in and these are made from a number of materials including wood, plastic and metal.  Some are just empty boxes with shelves and a door but most professional AV Media Cabinets have a rack-mounted system.  The Unicol AV Media Cabinet is made of metal and can be ordered as a single or twin cabinet with a standard 19” rack mount system built in; also included is the ability to add up to 1 x 55” TV Display above the single cabinet and 2 x 55” TV Display above the twin cabinet. The units a predominantly used for AV equipment and a standard single cabinet is 500mm wide, 700mm high and 500mm deep.<!

It should be mentioned at the outset that all the equipment in this article refers to the Audio Visual professional market and not consumer TV Display stands.  There are a variety of professional TV Display Stands and some are free-standing, some fixed or bolt-down and others on wheels.  The deciding factor in choosing the right one for you starts with the size and weight of the screen or TV Display you are going to use with the stand.  Nowadays modern TV Displays are light in weight until you reach sizes of over 70” or those with touch capabilities so below these sizes, the weight will not have a bearing on the choice of stand.

Slide Projector Introduction
The 1950’s saw the introduction of 35mm slide projectors which were the direct descendants of the larger format Magic Lantern first introduced in the 1850’s. They were mostly used in the home as a form of home entertainment but also gathered popularity in education and other institutional settings. The early 1960’s saw the introduction of carousel slide projectors which used a rotary tray to show 35mm slides.
