... The TB1311AFG does not support weak signals, ghost signals or other nonstandard signals. Therefore, these signals should be dealt with through the use of another device capable of handling these signals, such as a color-decoder. In these cases, the signal switcher and the video circuits of the TB1311AFG can be used. In some cases, “no-input detection” can be also used for these signals. ...
