Calculation formulas for projection distance Q
Any other projection distance can be obtained according to the screen dimensions (m) using the following 
calculations. The calculation result is with the "m" unit. (The calculated distance below may contain a certain 
error.) If the screen dimensions are written as "SD",
For 4*3 aspect ratioFor 16:9 aspect ratioFor 16:10 aspect ratio
Screen height (SH)= SD × 0.6= SD × 0.490= SD × 0.530
Screen width (SW)= SD × 0.8= SD × 0.872= SD × 0.848
Min. projection distance (LW)= 1.488 × SD= 1.350 × SD= 1.314 × SD
Max. projection distance (LT)= 1.632 × SD= 1.482 × SD= 1.441 × SD
Note
The throw ratio is 1.55 to 1.70:1 when the projection size is 100 inch. z

Getting Started
Before connecting to the projector
Read carefully the instruction manual for the device to be connected. z
Turn off the power switch of the devices before connecting cables. z
If any connection cable is not supplied with the device, or if no option\
al cable is available for connection of the  z
device, prepare a necessary system connection cable to suit the device.
Video signals containing too much jitter may cause the images on the scre\
en to randomly wobble or wafture.   z
In this case, a time base corrector (TBC) must be connected.
The projector accepts the following signals: VIDEO, analogue-RGB (with TTL sync. Level) and digital signal. z
Some computer models are not compatible with the projector. z
When using long cables to connect with each of equipment to the projecto\
r, there is a possibility that the image  z
will not be output correctly unless a compensator is used.
For details on what video signals the projector supports, see “List of compatible signals”. ( zÆpages 64-65)
Attention
When connecting with a video deck, be sure to use the one with a built-in time base corrector (TBC) or use a  TBC between  z
the projector and the video deck.
If nonstandard burst signals are connected, the image may be distorted. If this is the case, connect a TBC between the  z
projector and the video deck.
Note
Use an HDMI cable that conforms to HDMI standards such as an HDMI High Speed cable. If a cable that does not meet  z
HDMI standards is used, video may be interrupted or may not be displayed.  
When connecting the 1080p signal using HDMI, use a cable compliant with 1080p signal.
This projector does not support the VIERA Link (HDMI). z
