Some size modes are not available for certain types of input signals.
• For RGB1 and RGB2 input signals: VID AUTO, S1 AUTO or VID AUTO (PRIORITY) cannot be
selected.
• For VIDEO input signals: DEFAULT, S1 AUTO or VID AUTO (PRIORITY) cannot be selected.
• For an NTSC signal with VIDEO or S-VIDEO input: DEFAULT cannot be selected.Note
Size modes
•DEFAULT:Pictures are displayed without changing the aspect ratio of the input signals.
• THROUGH:Pictures are displayed without changing the resolution of the input signals.
•ZOOM:Pictures can be displayed in various magnifications. The user can magnify the pictures with the
magnification ranging from 50% to 999%, and the fiducial point is set on the top left of the screen.
• 4:3:Pictures are displayed in the aspect ratio of 4:3.
•16:9: Pictures are displayed in the aspect ratio of 16:9.
• S4:3: Pictures are scaled down to 75% of the original size without changing the aspect ratio of the input signals.
This mode is used when projecting the 4:3 pictures on the 16:9 screen.
• HV FIT: Pictures are displayed on the whole panel pixels.
If the aspect ratio of the input signals is different from that of the panel, the pictures are displayed by
converting it into the panels aspect ratio (4:3 for PT-D7500U and 5:4 for PT-D7600U).
• VID AUTO:The projector identifies the video ID (VID) embedded in the picture signals and displays the picture by
automatically switching the screen sizes between 4:3 and 16:9.
This function is effective for the video and S-video input.
• S1 AUTO:The projector identifies the S1 signal and displays the picture by automatically switching the screen
sizes between 4:3 and 16:9.
This function is effective for the S-video input.
• VID AUTO (PRIORITY): The projector identifies the abovementioned VID or S1 signals and displays the picture
by automatically choosing the screen sizes of 4:3 or 16:9 according to the VID if it is
detected or S1 signals if a VID is not detected.
This function is effective for the S-video input.
