AdvancedSize and Position In the Size and Position Menu, you can increase or decrease the size of your image, change its proportion (aspect ratio), move the image to a specific area of the screen, and refine other related parameters. Use Size and Position controls to match the image precisely to the screen. Changes made in the Size and Position menu take effect immediately and are saved when you exit the menu. Size Presets: Select a Size Presets option to quickly display an image in its native resolution or to automatically resize an image to closely fill the projector’s native resolution of 1920x1080, or to optimize the display width or height. Note The “native” aspect ratio is with the primary lens only. With an anamorphic lens in the light path, the aspect ratio is 2.35:1. Size, Position and Blanking parameters automatically adjust accordingly. If Blanking is set first, which defines an Active Input Area, Size Preset scaling occurs in this region of interest only. The default setting is either No Resizing or Custom, depending on the input signal resolution. Do not change it unless specifically instructed to do so by Vidikron Technical Support. •No Resizing: Select No Resizing to display the image in its native resolution, which may or may not match the projector’s resolution. For example, for a computer display with a native resolution of 800 x 600, “No Resizing” uses the central 800 x 600 pixels and has a black border – the black border areas are unused pixels. 19201080108010801080192019201920SVGA 800x600Source TypeNTSCHDTV 720pHDTV 1080iNo ResizingActiveImageAreaActiveImageAreaActiveImageAreaActiveImageAreaUnused PixelsUnused PixelsUnused Pixels Figure 3-20. Resize Presets: No Resizing For 1080i digital and 1080p signals, channels are pre-configured at the Vidikron factory for each aspect ratio. These channels use Custom size presets to achieve the selected aspect ratio. •“Custom” Resizing: The “Custom” re-size descriptor automatically appears in the Size and Position menu when any of the values for Size, Height, Horizontal Shift, Vertical Shift or Blanking do not correspond to those for a preset. This option is not offered in the Size Presets pull-down list. Other resizing options are described below, for the sake of completeness. In actual practice, though, they are rarely (if ever) used when the Vision 140/150 is used with the VHD Controller. •Default Resizing: When you select a new source, the image utilizes as much of the projector’s display area as possible for the type of incoming source data, but with minimal or no changes to aspect ratio. The image will be centered and displayed as large as possible depending on the source type and projector model: •A video image or 4:3 graphic image is enlarged to fill the screen height, centered between black side bars. •A 5:4 graphic image is enlarged to fill the screen height and is centered between black side bars. •An anamorphic (16:9) image fills the whole screen. •Full Size: Select Full Size to use all pixels for displaying the image, regardless of source or original aspect ratio. Incoming source material having a different aspect ratio than the projector will be stretched to fill the display. •Full Width: Select Full Width to fill the projector’s display from left-to-right without changing the original aspect ratio of the image. Depending on the source, data at the top and bottom may be discarded (cropped), or the display may have black borders at the top and bottom (called “letterbox”). •Full Height: Select Full Height to fill the display from top-to-bottom. Depending on the source, this may create borders. •Anamorphic: Select Anamorphic to display an anamorphic image in its native 16:9 aspect ratio. The image will fill the whole screen. Size: “Size” controls both the image width and height in tandem, maintaining the current aspect ratio (proportion) of the displayed signal data. Height: “Height” adjusts the image height while keeping the width constant. Use this setting to change the aspect ratio of the display. Pixel Tracking: Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. Proper pixel tracking helps ensure that the image quality is consistent across the screen, that aspect ratio is maintained, and that pixel phase can be optimized (see below). Tracking determines the frequency of the pixel sampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a particular source are sampled. By default, the projector samples at the correct frequency for most sources. For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black and white pixels, or a similar “half on, half off” graphic image.
