Recommended Sync Signal Timing
Horizontal sync duty should be 3 to 30%.
Horizontal sync width should exceed 0.9 µsec.
Horizontal back porch should exceed 2.0 µsec at sync on green and 1.2 µsec at others except when at 15KHz.
Horizontal blanking should exceed: 7.0µse at fH 15.75kHz, 3.3µsec at 30 kHz<fH<50kHz, 2.9µusec at 51kHz<fH<80kHz,
and 2.7µsec at 81kHz<fH<95kHz
Vertical sync duty should be 0.2 to 10%.
Vertical sync width should exceed 40 µsec or 2 horizontal lines.
Vertical sync width plus back porch should exceed 0.4 msec.
Interlaced signals are not recommended.
Interlaced signals with composite sync may not be displayed.
