Display Method For 16:9 Screen Ratio [Recommended]; Settings And Display For Applications That Support 16:9 Screen Ratio Display [Required]; Trap Filter [Recommended]; Support For 4:3 Aspect Ratio [Required] - Nintendo Wii Programming Manuallines

6.15 Display Method for 16:9 Screen Ratio [Recommended]

When supporting a 16:9 screen ratio, we recommend the method that horizontally stretches the 4:3
ratio display.
This is because this method is the most common one as a TV function. Stretching an image from 4:3
to 16:9 also yields a higher resolution image compared to a letterbox display, which chops off the top
and bottom of 4:3 ratio display.
When an aspect ratio of 16:9 has been set for the Wii console, the user is advised to switch the
television to a wide-screen display by means of an on-screen message and a cautionary note in the
Wii console user's manual.
6.16 Settings and Display for Applications That Support 16:9 Screen
Ratio Display [Required]
If an application supports the 16:9 screen ratio, be sure that the display is in the appropriate format
according to the aspect ratio set for the Wii console.
Although it is all right for an application to have a separate aspect ratio setting, the default setting for
the application should not only conform to the Wii console setting, but any changes to the application
setting should not impact the Wii console setting.
Applications not supporting the 16:9 screen ratio may ignore the Wii console setting.

6.17 Trap Filter [Recommended]

When there is a large contrast in brightness, such as with a white font on a black screen or a black
font on a white screen, and a small font size is used, please enable the trap filter.
If the trap filter is disabled when displaying such an image on some CRT television sets with high
contrast, the effect of cross color may become pronounced and distort the outlines of characters.

6.18 Support for 4:3 Aspect Ratio [Required]

Applications must always offer support for the 4:3 aspect ratio. Do not create applications on the
assumption that they will only be displayed in the 16:9 aspect ratio.
6.19 Checking the On-screen Display during Application Startup
[Required]
Regardless of the display mode used for the Wii menu, you must verify that a game application can
be displayed normally. Although game applications are not required to support all display modes
(progressive, UERGB60, and 16:9), the Wii menu does include all display modes. For example, game
applications that do not support progressive display must be displayed normally even if the Wii menu
is being displayed in progressive mode.
