• 16:10 (for WUXGA model only): This format is for 16:10 input sources, like widescreen laptops.
• LBX: This format is for non-16x9, letterbox source and if you use external 16x9 lens to display 2.35:1
aspect ratio in full resolution.
• Native: This format displays the original image without any scaling.
• Auto: Automatically selects the appropriate display format.
Note:
• Detailed information about LBX mode:
– Some Letter-Box Format DVDs are not enhanced for 16x9 TVs. In this situation, the image will
not look right when displaying the image in 16:9 mode. In this situation, please try to use the
4:3 mode to view the DVD. If the content is not 4:3, there will be black bars around the image
in 16:9 display. For this type of content, you can use LBX mode to ll the image on the 16:9
display.
– When using an external anamorphic lens, the LBX mode allows you to watch 2.35:1 content,
including Anamorphic DVD and HDTV lm sources. In this case there are no black bars, light
source power and vertical resolution are fully utilized.
