• Keep this user guide in a safe place for later reference.
• Read all warnings and follow all instructions.
• Ensure there is no direct airflow from air conditioning blowing on the display.
• Do not use the device near water. To reduce the risk of fire or electric shock, do
not expose the device to moisture.
• Avoid exposing the device to direct sunlight or other sources of sustained heat.
• Do not install near any heat sources such as radiators, heat registers, stoves, or
other devices (including amplifiers) that may increase the temperature of the

particularly at the plug, and at the point where it emerges from
the equipment. Ensure that the power outlet is located near the
equipment so that it is easily accessible.
• Only use attachments/accessories specified by the manufacturer.
• When a cart is used, use with caution when moving the cart/equipment

The is the ra俿o of the image width to the image
height.
Auto
Scales an image propor俿onally to t the projector’s na俿ve
resolu俿on in its horizontal width. This is suitable for the
incoming image which is neither 4:3 nor 16:9 and you want to
make the most use of the screen without altering the image’s
aspect ra俿o.
4:3
Scales an image so that it is displayed in the center of the screen
with a 4:3 aspect ra俿o. This is most suitable for 4:3 images like
computer monitors, standard deni俿on TV, and 4:3 aspect DVD
movies, as it displays them without aspect altera俿on.
Brightness
16:9
Scales an image so that it is displayed in the center of the screen
with a 16:9 aspect ra俿o. This is most suitable for images which
are already in a 16:9 aspect, like high deni俿on TV.
Na俿ve

Tint
Sharpness
The higher the value, the more greenish the picture becomes.
The lower the value, the more reddish the picture becomes.
Refers to the amount of that color in a video picture. Lower
se濿ngs produce less saturated colors; in fact, a se濿ng of “0”
removes that color from the image en俿rely. If the satura俿on is
too high, that color will be overpowering and unrealis俿c.
A high value results in a sharper picture; a low value so㿿ens the
picture.

Moderator Mode allows the moderator to take control of the devices connected to
the ViewBoard or display. To enter Moderator Mode, select the Moderator Mode
icon ( ) located in the lower-right corner of the screen.
When enabled, the moderator can view a list of all connected screens in the le㿿
⿿oa俿ng window and can preview each par俿cipant’s screen and then select any
of par俿cipant’s screen and cast to the ViewBoard’s or display’s main screen for
presenta俿on. The moderator can also control each par俿cipant’s screen, annotate
on the ViewBoard or display, and remove unwanted par俿cipants by selec俿ng the
close icon (X).
79
Page 80
When enabled, the ViewBoard’s screen will be broadcasted to all of the
par俿cipant’s connected screens simultaneously. The par俿cipants can only view the
presenta俿on contents un俿l the moderator disables the Broadcast func俿on.
By default, vCast is set to allow mul俿ple screen sharing, but can also be set to single
screen sharing. To do this, the moderator can select the Mul俿ple Screen Sharing
icon to switch to single screen sharing.
By default, vCast is set to let the moderator preview the par俿cipant’s screen
contents prior to sharing to the ViewBoard. Selec俿ng the Preview Screen icon, the
Moderator can switch to see the par俿cipant’s name only.
By default, par俿cipants can use touch for collabora俿on a㿿er connec俿ng. The
moderator can enable/disable the touch func俿on of a par俿cipant by selec俿ng the
Touch icon in their window.
• Moderator Mode is supported on all vCastSender and AirPlay devices, but
mobile devices are limited to a “preview” func俿on. Addi俿onally, mobile
Android devices cannot cast sound out.
• When you cast your Windows/Mac/Chrome screen to a ViewBoard or
display, the selected full screen unit will not be broadcasted back to your
device to avoid repe俿俿ve screen cas俿ng.
• The ac俿ve presenter can touch each of the par俿cipant’s screens to
remotely control cas俿ng devices.
• The number of mul俿-screen presenters on-screen depends on your
Windows CPU processor performance and router specica俿ons.
