* Recommended horizontal and vertical timing condition
• Horizontal sync width duty should be more than 4.8% of
total horizontal time or 0.8 µs, whichever is larger.
• Horizontal blanking width should be more than 2.3 µsec.
• Vertical blanking width should be more than 450 µsec.
** If the input signal is Generalized Timing Formula (GTF)
compliant, the GTF feature of the monitor will automatically
provide an optimal image for the screen.
