The purpose of this page is to inform about typical display issues common to wii homebrew. Unwitting developers and users seeking information/help concerning their display problems should be directed here in order to avoid wasting time with lengthy explanations.

The Problem

Not all television sets are created equal. This means that the display area will often mismatch the actual picture. If a developer does not properly compensate for certain factors, the results are usually not good. There will be ugly black borders on some user's picture output and in some cases certain elements will even be placed outside the physical display range, such as buttons and status elements (health, lives, ammo, score, etc). For the end-user, this can be frustrating and even confusing.

Preventative Measures for Developers

The first and easiest thing to do is make sure not to place anything like buttons or status displays too close to the edges of the screen, because this creates the likelihood of having them partially or completely cut off. The BBC recommends keeping a margin of 5 percent on each side. There's also a way to specify a bigger or smaller output such as in the following example:

...

rmode = VIDEO_GetPreferredMode(NULL);

if( CONF_GetAspectRatio() )
{
	rmode->viWidth = 678;
	rmode->viXOrigin = (VI_MAX_WIDTH_PAL - 678)/2;
}

...

But of course this will not yield the same results for everyone. Some users will be pleased with certain settings and others will not. The best thing to do is to allow the user more than one option so that they can pick whatever best suits their television.

List of Applications and Display Support

This are tables based on user feedback indicating whether or not a the latest version of a given application is likely to show correctly on different types of displays. If an appears it means support is absent or incomplete, meaning some users may experience problems with the particular display type while others will not. If a appears, then it means that app works well with that display type (no screen elements out of physical display range and no black bars). Console mode applications are not included.
