The source video is scaled so that your display is showing full screen. Note: if the source video contains horizontal black bars, as do some DVD movies, the full screen video will also contain black bars. Select this option if the aspect ratio of the display device showing full screen video has the standard 4:3 aspect ratio (standard TVs and monitors). Select this option if the aspect ratio of the display device is showing full screen video has a 16:9 aspect ratio (widescreen HDTVs).

Moving the slider to the left will maximize application performance, while moving the slider to the right will optimize 3D image quality. Moving this slider from one position to the next changes the individual Custom Settings sliders found below. When Custom Settings is checked, the Main Settings slider is disabled, allowing you to move each individual slider in the Custom Settings section below.

SmoothVision 2. 1Anti-Aliasing improves image quality by removing jagged edges from 3D images, resulting in smoother, more naturallooking lines and contours. Selecting Application Preference will result in high quality images, with negligible reduction in the application's performance. SmoothVision 2. 1 Anti-Aliasing can be applied using different number of samples (2X, 4X, 6X). Anisotropic filtering uses a texture filtering technique that blends multiple texture samples together. Selecting Application Preference will result in sharper textures, with a negligible reduction in the application's performance. The number of samples taken when anisotropic filtering is performed can vary. By moving this slider to the right, the number of samples taken increases and the quality of the final image increases. 16X provides maximum detail, crisplooking images as a result of the largest number of texture samples possible.
