The video projector is probably one of the greatest inventions since the
telephone. It has made multimedia presentation a walk in the park. It has
become an essential device for religious services, seminars, classroom
lectures, or product presentations.
It has done away with the overhead projector which projects visual aids
from acetates. Even writing on a blackboard or white board has become
unnecessary because you can present your concepts on interactive media
complete with animation.
Here are some tips on using a video projector with a computer.
When setting up a projector, make sure that it is perpendicular to the
projection screen or wall.
Use the keystone adjustment to compensate for the tilt of the projector.
Be sure that the cable connections are fixed properly.
Turn the projector on first to make sure that the computer reads it as
the primary monitor.
Tweak the graphic options and select the output “extended desktop.” (This
is true for an Acer pc; it may vary with other brands or operating
systems.) This doubles the “length” of your desktop. Imagine that you have
two desktops side by side; your cursor can cross between the two. The left
desktop can be seen on your computer screen, this is your primary monitor.
While the right desktop can be seen on the projected screen, this is your
If you are using the Easy Worship application, look for the monitor icon,
click it and under “output to” select “secondary monitor.” This part is
important because if it is not done, the audience can see the multimedia
operator editing stuff on the secondary monitor, which is the projected
screen. That should not be the case. The operator should be doing his thing
on the primary monitor only, that is the computer screen, which is not seen
by the audience.
If the venue has a low ceiling, it should be noted that worship
presentations should be adjusted to compensate for this. You see, if the
people are standing, only the upper half of the projected screen is visible
to the people at the back. To make up for this, the text of your
presentation should be limited to the upper half of the screen. However,
this technique is not applicable if the audience is sitting down.
