Select the Appropriate CineWide Scaling Method: CineWide and CineWide with
AutoScope both produce the same image geometry for a given aspect ratio (refer to Table
4-2). However, when the viewer selects the 16:9, 4:3, Letterbox or VirtualWide aspect
ratio, CineWide uses different scaling algorithms to compensate for the fact that the
anamorphic lens is always in front of the primary lens.
To configure the Q-750i to use the appropriate CineWide scaling method:
1.
Press MENU on the remote control.
2.
Select Control from the Main menu and press ENTER.
3.
Select CineWide from the Control menu.
4.
For a Q-750i/CineWide (fixed anamorphic lens), choose CineWide. For a
Q-750i/CineWide with AutoScope (motorized anamorphic lens), choose AutoScope.
Configure Lens Motor Trigger (Q-750i/CineWide with AutoScope only): CineWide
with AutoScope maintains constant image height independent of the aspect ratio, while
using the full display resolution of the projector. It accomplishes this by moving the
anamorphic lens in front of the primary lens when widescreen material is being viewed.
When the viewer transitions back to 16:9 or 4:3 source material, the anamorphic lens
moves out of the light path.
To configure the lens motor trigger on the Q-750i for proper AutoScope operation:
1.
Press MENU on the remote control.
2.
Select Control from the Main menu and press ENTER.
3.
Select Trigger 1 or Trigger 2 (whichever one is connected to the lens motor) from the
Control menu.
4.
Set Trigger 1 or Trigger 2 to “AutoScope.” This enables the lens motor to move the
anamorphic lens into position (in front of the primary lens) when the Cinema or Virtual
Cinema aspect ratio is selected.
5.
Select the Cinema or Virtual Cinema aspect ratio to move the anamorphic lens into
position, if it isn’t already. To do this, press CINEMA or VCINE on the Q-750i remote
control (Figure 2-3).
Adjusting the Horizontal (X) Lens Position:
1.
Project a white field on the screen.
2.
Loosen the Yaw/X-Adjustment Levers underneath the lens.
