is presented. Technology plays a significant role in education today. Classroom
projects are used to present an illustration, image, etc. which makes learning

However, we recommend certain things to consider before
they venture into buying a projector.
Color
The first and foremost thing is when you’re buying a
projector for educational purpose for your school, consider the picture – it
should give images that attractive to the learners. To make this all you need
to consider multiple points. Consider the lumen factor for white brightness and
color brightness.
Contrast
ratio
A high-contrast ration makes the image rich, and clear
in detail. LCD technology can provide contrast ration up to 200000:1
How
easy it is
Make sure to check it has a feature of getting on/off
as soon as it is triggered. Easy connection to audio is important.
Resolution
Resolution is the number of dots in an image. Higher
resolution gives better quality image and lower resolution gives low quality
image.
Resolution comes in two types: XGA, SVGA, WXGA and HD
in one set. The other set is the number of vertical and horizontal pixel lines
that the projector is making.
SVGA corresponds to 800 x 600, XGA to 1024 x 768. Thus,
if you opt for SVGA projector, it will bring you great images of 800 pixel wide
and 600pixel height.
Connectivity
Check whether the projector is compatible with USB device,
and has display port which is important for connecting computers, televisions,
and DVD players.
Interaction
In the classroom, interaction is important to make
learning engaging. Interactive ability of the projector help you show and
explain the content from diverse sources and create big or small interactive
areas using interactive devices (interactive pens).
Distance
and positioning
The throw distance of a projector is the distance
between the projector and image. Choose short throw, long throw or ultra short
throw depending on the size of the room where the projector is played.
Image
adjusting
Check if automatic adjustment is available. You need
not go to the menu to change the setting and adjust. When the projector is not
placed centrally it may result in images tilted to one side. The lens, image
quality correction etc. should be there.
