Common Features for Portable Video Magnifiers
Portable video magnifiers
come with various features. These are discussed here below:
Monitors
Portable video magnifiers
come with monitors of different sizes. Generally speaking, he larger the size
of the screen, the larger the space they take up, which is a disadvantage. The
desktop types are preferable in terms of space utilization, especially the flat
screen ones.
X/Y tray
The versatility of x/y
tray is in the fact that they can accommodate various materials, albeit more
space is needed for this function. In such a scenario, then the desk space
would be needed to allow the side and front and back movements of the x/y tray.
This is in fact an important consideration that you have to make when acquiring
portable video magnifiers.
Magnification Range
Not all portable video
magnifiers have the same range of magnification; some have high other s medium
and others have low. Apart from the manufacturer’s specification, the rule of
the thumb is that the more the magnification, the less of the magnified space
can be seen and vice versa. Ensure that you get an overview mode so that you
can be able to start with low magnification and increase as the need arises.
Colour of display
As a matter of fact, some portable video magnifiers come with black and white display especially for
those who want to read text or newspapers; others, on the other hand will come
with full colour display. What distinguishes both is the fact that the full
colour ones are more expensive than the black and white ones. This is an
important consideration when buying one.
Reverse Video
For those people who
experience too much light that is blinding, this feature helps change the black
text on white paper so that they appear as white letters on a black surface. |
