EXTRA FEATURES
  Direct power on - start up time is significantly reduced  
as standby mode is bypassed when the power cable is 
inserted into an active power outlet. This eliminates the 
need to use the ‘Power’ button on the remote control  
or the projector keypad.
  Auto power off - if after a pre-determined time the projector 
does not receive a signal, it will turn itself off automatically, 
conserving power and extending the life of the lamp.
  Key pad lock - once enabled, prevents unauthorised 
adjustments ensuring the projector can only be controlled via 
the remote control.
  +12v Trigger - electric screen control
  Logo Capture - customise your start up screen

† 3D TECHNOLOgY
Using  the  inherent  speed  of  DLP  technology,  The  Optoma  EX785  can  output  video  and  images  at 
an astonishing rate of 120Hz, allowing you to show full screen, full colour, stereoscopic 3D. The 3D 
effect is generated by splitting this signal into two standard video streams, one for each eye. Using 
DLP
® Link™ technology, the 3D glasses synchronise with the image on screen to filter each stream 
to the correct eye. Your brain then combines the two streams to make them jump into life.
The 3D features of the EX785 can only be used with compatible 3D content. Typical applications include 
use with 3D educational or 3D design and modelling software. Currently the EX785 does not support 
3D  TV  broadcast  systems,  SKY  in  the  UK  or  3D  Blu-ray,  though  support  for  these  applications  may   
be added in future using additional hardware.
