Some of the many ways that someone can use to give appeal to the
information they want to pass to their target audience is by using a
computer projector. The use of this image presentation device can go a long
way in ensuring that the host gets the kind of attention that they want
from the audience. In addition, it lets them take charge of how they
deliver the massage in terms of altering the audience emotions when they
want to drive a point home.
The computer projector itself is a class of image device that beams wider
mirror images, video and data from the gadget on white flat screens or
surfaces. What makes the image presentation possible is the projector’s
lamp that produces the ray of light required for the image to be visible on
the presentation surfaces. However, the brightness level that best suits a
presentation will greatly depend on the size of space and intensity of
light within the room. For dark spaces, computer projector lamps rated
above 300 ANSI lumens is good enough but for well-lit medium space
projector lamps with more than 750 ANSI lumens rating provides excellent
viewing and note taking during presentations. However, the current breed of
projector with the liquid crystal display (LCD) technology has costly,
short life but bright metal halide lamps with a light intensity of around
two to four thousand ANSI lumens.
Another important factor that one needs to consider when selecting a
computer projector is their resolution. This simply implies that
individuals should select a computer projector that suits the image detail
level of their presentation. For those with simple power point slide show
legacy projectors with a low resolution of 640×480 pixels will do the job
perfectly. However, if the presentation in have low-resolution images or
animations the host presenter may need to upgrade their computer projector
gear to 800×600 pixels to get quality staging. Furthermore, incase one
wants their audience to have a good movie experience from the
high-resolution video that they want to display a 1024×768 pixels computer
projector will provide an excellent entertainment for viewers.
There are also a number of compelling reasons for presenters to consider
using a computer projector instead of slide or overhead film projectors.
Namely, they have professional looks, they display images, videos and data
at the same cost, they are stylish and portable and they can present data
and audio from the local or online network. What more, they are compatible
with both analog and digital electronic media content. Besides this
computer projectors also have some draw backs due to their rigid design
specifications. For instance, if one wants to get the best out of a
computer projector they use for presentation, they must to have specific
type of connector to link their computer or media source to the projector.
They perform poorly in terms of audio volume. Lastly, it is almost
impossible to adjust the sequence of image clips on the computer projector
during presentation without messing around with the media source.
