If your measured projection distance is 2391 mm, the projected screen
size is 90-inch.
Note
• All measurements are approximate and may vary from the actual sizes.
• BenQ recommends that if you intend to permanently install the projector, you should physically
test the projection size and distance using the actual projector in situ before you permanently
install it, so as to make allowance for this projector’s optical characteristics. This will help you
determine the exact mounting position so that it best suits your installation location.
Using the projector in an outdoor
setting
The projector is designed mainly for indoor use but its portable design
also allows it to support occasional outdoor use. When using the projector
outdoors, the following items are suggested to enhance the viewing
experience:
• Install the projector on a tripod if there is no flat surface to place the
projector. See "Working with a tripod (purchased separately)" on page
78 for more details.
• Set a preferred picture mode (except
Night Shift)
to the most suitable
setting. See "Choosing a proper picture mode for video streaming" on
page 49 for more details.
Using the projector at high altitude
We recommend you use the High Altitude Mode when your environment
is between 1500 m - 2000 m above sea level, and ambient temperature is
between 0°C to 30°C.
Operation under High Altitude Mode may cause a higher decibel operating
noise level because of increased fan speed necessary to improve overall
system cooling and performance.
If you use this projector under other extreme conditions excluding the
above, it may display auto shut-down symptoms, which is designed to
protect your projector from over-heating.
In cases like this, you should switch to High Altitude Mode to solve these
symptoms. Go to
> All settings > Projector > Advanced Settings > More
> High Altitude Mode.
However, this is not to state that this projector can operate under any and
all harsh or extreme conditions.
