Aspect ratios explained
Plasma screens come in one of the two aspect ratios
below:
4:3 aspect ratio - This is the same shape screen as a
computer monitor or non-widescreen television. The width of the
screen being 4 parts long and 3 parts high. This gives you a
rectangular screen.
16:9 aspect ratio - This is the 'widescreen' television
screen shape. The width of the screen being 16 parts long and 9
parts high.
Connection to equipment
Plasma screens from any
manufacturer can be connected to a computer and video
recorder/TV/satellite system. If, for example, you connect the
plasma screen to a video recorder and a computer, you can then use the
remote control to switch between the two as required. This can be
very useful for presentations, training or inductions, where you need to
present using PowerPoint but also show a video in the middle of your
presentation.
Stands and mounts
Most plasma screens are supplied without a stand or
mount. You will then choose either a table stand, wall mount or
ceiling mount at extra cost. Wedgwood can also supply a
mobile plasma screen stand/trolley to support any
manufacturer's plasma screen.

Speakers
Plasma screens have built-in speakers for a limited
volume output from either your computer or video. Most also have
speakers that can be attached to the plasma screen to increase this
volume and give better quality sound. These are optional extras.
Life of plasma screens
This varies considerably between manufacturers but
usually from 20,000 to 30,000 hours. After this time the plasma
screen will only be at around half the original brightness. 20,000
is 833 days or 2.3 years of continuous 24-hour use. This is
one advantage plasma screens has over LCD projectors which have a bulb
life of usually 2,000 hours before replacement.
Video walls
Plasma screens can be connected together to display a
single image as a video wall. This required extra hardware.
