Panasonic Projector PT-D7500U Operating Instructions

							41
If the focusing, zooming or positioning of the image projected on the screen is not successful, even though the
projector is properly positioned against the screen, you can adjust the focus, the zoom, or the vertical or horizontal
position of the image.
Do not move the lens beyond the bounds of the shift range as this may cause a change in the focus. This limitation
is to protect the parts of the projector.
Press the LENS button on the remote
control or on the control panel of the
main unit.
Pressing the button changes the setup screen in
the order of 
“LENS FOCUS”, “LENS ZOOM” and
“LENS SHIFT”.
Choose an item and adjust it using
buttons.

Automatic adjustment (AUTO SETUP)
Automatic adjustment function adjust the resolution, clock phase and image position automatically when dots-
structured analog RGB signals such as computer signal are supplied. (Automatic adjustment is not available if
signals or moving images other than analog RGB signals are supplied.)
It is recommended to supply images with a bright white frame at the outermost periphery containing characters etc.
that are clear in white and black contrast when the system is in automatic adjustment mode.  Avoid supplying
images that involve halftones or gradation such as photographs and computer graphics.
Note
• A message “COMPLETE” appears if adjustment is ended normally.
• “CLOCK PHASE” may have been shifted even when the adjustment ended normally.
In this case, manually adjust the “CLOCK PHASE”.
• If an image with blurred edges or a dark image is supplied, a message “INCOMPLETE” appears,
indicating the automatic adjustment was unsuccessful.
In this case, manually adjust the items of “INPUT RESOLUTION”, “CLOCK PHASE” and “SHIFT”.
• For specific signals and long-sideways (or landscape) signals such as 16:9, adjustment should be
made according to “AUTO SETUP” in the option menu.
• Automatic adjustment may not be available depending on the machine type of the personal computer.
• Automatic adjustment may not available for synchronization signal of C-SYNC and G-SYNC.
• Image may be disturbed for about 4 seconds during automatic adjustment, which is not an abnormal
error.
• For every supplied signal, adjustment is required.
• Automatic adjustment can be cancelled by pressing the MENU button during the course of automatic
adjustment.

Registration of input signal data
The input signal data must be registered because it is not registered on shipment of the projector.
• Up to 96 input signals can be registered.
• Registration is performed by supplying the signal that corresponds to the mounted input module.
Note
Registration of new data
When a new signal is supplied, press the MENU button on the remote control or operating section of the main unit,
and a “NEW SIGNAL INPUTS” screen appears.

Registration of input signal data
Sub memory
The projector is provided with a sub memory function to register plural pieces of image adjustment data even they
are determined to be the same signal by the frequency and form of the synchronization signal source.
Use this function when the user needs adjustment of picture quality such as aspect switching and white balance
using the same signal source.
Sub-memory contains all data that can be adjusted by signals such as screen aspect ratio and image adjustment
data (BRIGHT, CONTRAST etc.).
How to register into sub memory
A new signal cannot be registered into sub memory. A new signal must undergo signal registration.
