I purchased two 32 inch screens to place in "compressed video" classrooms a
year or so back. These were small rooms with onlyi about 12-15 viewers at
any given time, and I was not real happy with the results, from the back of
the room - even just showing the in-room computer desktops. So- the next
three I ordered were the 42 inch screens. These give me or the instructors
the capability of viewing both our own classroom, and the opposite classroom
(at the other end of the circuit) at the same time- and still be able to
read the computer desktop signals from either room. They certainly are
not like having a purpose built monitor right in front of you, but
acceptable for students tol view what is going on. They are able to use
their own desk top machines which can be switched onto the larger screens so
that others in both their classroom, and at the other campus, to see what
they are doing and talking about. Prior to the purchase of these, I used
video projectors which can throw a very large
image on the wall, but actually with less color and acceptance by the
students, at the back of the room.
Prior to my arrival at the college, they were using lare and old portable
projectors which were noisy and dim. The new projectors in the larger
classrooms, and the monitor screens in the smaller rooms were well accepted,
and the "white boards" (Smart Board brand) used to project on, in the
computer and math/science rooms proved to be an outstanding buy. You can
buy a white board whein you place the projector either in front or behind
the screens, and the board becomes a "touch screen". Would be great to have
one here in the ham shack, but the price of the projector would be minimum
of 1 K, and the board another K. Bit pricey for a monitor replacement for
me.
