Runco Q-750D operation manual •The default setting, Auto, functions as follows

Operation

Display Device - Configure: The options in the Display Device - Configure menu allow you to change the picture orientation, perform lens adjustments or access other, display-device specific functions.

•Installation – Orientation: Select Installation from the Display Device - Configure menu, then select Orientation to change the picture orientation to suit the method of installation (Floor Front, Floor Rear, Ceiling Front or Ceiling Rear). Or, for front-projection installations, use the Auto setting to have the projector automatically determine the orientation (floor or ceiling) using an internal sensor.

•Diagnostics: Select Diagnostics from the Display Device - Configure menu, then select Red, Green, Blue, Yellow, Cyan or Magenta to display only that color channel (simulating a filter of that color). This can be useful for calibration or measurement purposes.

To restore the normal picture (all colors), select White.

•Altitude: Select Altitude from the Display Device - Configure menu to control the operation of the projector’s cooling fan.

In most cases, the default setting (Auto) maintains the correct operating temperature. If the projector frequently turns off due to overheating, or in certain high-altitude operating environments, you may need to change this setting to High.

Color Space: Select Color Space from the Service menu to choose the color space of the source signal for HDMI, RGB, and component connections.

•The default setting, Auto, functions as follows:

•HDMI: If the Auxiliary Video Information (AVI) infoframe contains color space and/or range data, the DHD Controller uses that information. Otherwise, for RGB sources, the DHD Controller uses the RGB-Videocolor space. For component SDTV and EDTV resolutions, REC601 is used. For other component video resolutions, REC709 is used.

•RGB: If Hsync or Vsync signals are present, the DHD Controller uses the RGB-PCcolor space. Otherwise, REC601 is used for SDTV and EDTV sources, and REC709 for all other sources.

•Component: For SDTV and EDTV resolutions, the DHD Controller uses the REC601 color space. For all other resolutions, REC709 is used.

In most cases, the Auto setting determines the correct color space to use. If it does not, you can force the DHD Controller to use a specific color space. Choose one of the following:

•REC709 sets the color space matrix to that defined in ITU-R BT.709.

•REC601 sets the color space matrix to that defined in ITU-R BT.601.

•RGB-PCuses RGB color space and sets black at 0,0,0 RGB and white at 255,255,255 RGB, assuming an 8-bit image.

•RGB-Videouses RGB color space and sets black at 16,16,16 RGB and white at 235,235,235, assuming an 8-bit image, to correspond to the luminance values defined in digital component standards.

Triggers: Select Triggers from the Service menu to configure the 12-volt trigger outputs. You can assign one or more trigger outputs to each aspect ratio. Those triggers are then activated by selecting that aspect ratio.

With a Q-750d/CineWide with AutoScope, assign at least one trigger output (the same one to which the lens motor is connected) to the Cinema and Virtual Cinema aspect ratios.
