Sync separation level
The sync separation level is changed according to the ratio of H-sync width to one line. Typical sync separation levels
for each format are as follows.

Format detection and sync separation performance are affected by the separation level set by HV-SEP setting and the
value of the connected coupling capacitor. Careful evaluation is required to set the separation level under consideration
of expected input conditions such as a suppressed sync input, an input with V-sag and APL (Average Picture Level)
fluctuations.
For “Sync on G” signal, HD-OUT is not output during V-sync period because there is no H-sync during V-sync period.
