  Installation
Obtaining a preferred projected image size
The projected image size is determined by the distan ce from the projector lens to the screen, the zoom 
setting, and the video format.
Projection dimensions
Use the illustration and the table below to he lp you determine the projection distance.
All measurements are approximate and may vary from the  actual sizes. If you want a permanent installation 
of the projector, we recommend that  you use the actual projector to physically test the projection size, 
distance, and the projectors optical  characteristics prior to the installation. This helps you determine the 
exact mounting position which be st suits your installation.

							14 Connection  
Connection
When connecting a signal source to the projector, be sure to:
1. Turn all equipment off before making any connections.
2. Use the correct signal cables for each source.
3. Make sure the cables are firmly inserted.
•  In the connection illustrations sh
own below, some cables may not be included with the projector (see 
Shipping contents ). They are commercially avai lable from electronics stores.
Connecting with video equipment
You need only connect the projector  to a video source device using just one of the connecting methods. 
Each video source provides differ ent picture quality. The method you choose most likely depends upon 
the availability of matching terminals on both the  projector and the video source device as described 
below:
In the connection illustrations show n below, some cables may not be included with the projector (see 
Shipping contents ). They are commercially ava ilable from electronics stores.
Connecting HDMI devices
HDMI (High-Definition Multimedia Interface) suppo rts uncompressed video data transmission between 
compatible devices like DTV tuners,  DVD players, Blu-ray players and displays over a single cable. You 
should use an HDMI cable when making a conne ction between the projector and HDMI devices.
Connecting smart devices
The projector can display contents directly from an  MHL compatible smart device. Using an HDMI to 
Micro USB cable or HDMI to Micro USB adaptor, you can connect your smart devices to the projector 
and then enjoy your contents on the big screen.
Some smart devices may not be compatible to the cable that you use. Please consult the manufacturer of 
your smart device for detailed information.
