Black and White Signal

Since Black and White signal decisions are made by the color killer level, the color killer bit must be turned “ON”.

When a user intentionally enables the B/W-bit, the automatic input signal detect function only checks if the Line number is

525 or 625. In this case, please refer to [ST-VLF]-bit information only.

*[UNDEF]-bit:

if the input signal type is not identified, this bit becomes “1”.
