BenQ IL430 Installation Handbook page 9

For IL430/IL490/IL550, when two displays place together,
the signal of the remote control is easily interfered by
the Touch screen signal.
• Do not place the remote control receiver of the display
parallel to the front frame of another display or its
signal will be interfered by Touch screen's signal. Please
keep the distance for at least 20 mm when placing two
30
monitors side by side.
• Use an IR extender cable (3.5 mm cable) to avoid
interference between IR remote controller and the
Touch Screen when placing multiple displays
side-by-side.
The remote control may not function properly when the
remote control sensor on the display is under direct sunlight
or strong illumination, or when there is an obstacle in the path
of signal transmission.
When using the remote control, make sure the display's
remote control sensor window is NOT exposed to
direct sunlight or strong reflected light, e.g. tile flooring.
