Windows Smart Tech Interactive Whiteboard 3840 X 2160 Interactive
1, Product Instruction :
Interactive whiteboard connects with a general computer by a USB
cable, the display output of computer can be projected on the
whiteboard through a projector. After calibration, touch and
tracking information from the board will be transferred into
pointer click and movement of the mouse, and by our software or
other program, all click, tracking and writing information will be
displayed on the board at real time.
2, Which type of projectors can be used with Interactive
1), If, after orienting, you find that the projected image does not
properly fill the screen, or suffers from distortion or shimmering,
the resolution settings of your projector and your computer may not
match. It’s very important that the computer and projector
resolutions correspond exactly.
2), Ensure that the projector is set to its optimal image
resolution. Refer to your projector’s manual for the true
resolution of your projector and reset it if necessary. While the
projector manual instructions may indicate that resolutions other
than the optimal one are permitted, you should not set the
resolution to any of these other settings.
3), When the projector is not placed properly, the image projected
on the whiteboard may turn out to be a keystone. When the projector
is placed front higher or rear higher, a vertical trapezium is
projected. When the projector is placed unevenly on both sides, the
projector is not in the center in comparison with the whiteboard,
or there is an angle between the projection direction and the
horizontal direction of the whiteboard, a horizontal trapezium of
another type is formed.
4), When the projected image is in the form of a keystone, the
image is distorted and thus should be adjusted.
5), When a vertical keystone is projected, you can use the special
adjustment button or elevate the projector to make an adjustment
(for more information, refer to the projector manuals).
6), When a horizontal keystone is formed, you can adjust the
location of the projector to the center of the whiteboard to
achieve front projection.
7), You must make a few final adjustments to the projector to
ensure a focused image that fits within the interactive whiteboard
frame at the top and bottom, with a margin of approximately 3/8" on
both the right and left sides.
8), NOTE: The 3/8" margin described above is an optimal
measurement. Alignment can vary: in some instances, the image can
fill the entire screen; in others, the margin can be greater than
3/8", but be perfectly satisfactory as long as it’s even on all
9), You can fix many projector-related problems right at the
projector itself, just by shifting the projector to the right or
left, tilting it or using the zoom lens to sharpen the focus or
expand and contract the image. You can also solve many keystone
problems by raising or lowering the front or back of the projector
until the sides of the image are parallel to the screen frame.
3, Why is the image projected by the projector in the shape of the
wrong size or distorted and how to adjust it?
1), Check whether the type of the whiteboard set in the driver
program complies with that of the whiteboard in use.
2), Check whether the whiteboard is correctly located.
3), No. Only special USB cable designed by Technology can be used
to connect the whiteboard and a computer, due to the unique
characteristics of data transmitted.
