Interface Frequency
The following frequency range is the working period. If the entered mode between below
period but not match the frequency of supported timing, display optimization not be
assured. If the entered mode is out of the working period, the display will be blanking
(just show “out of range”) then go to power saving.
Basically, mode judgment is regardless the sync polarity except both or more modes that
are all belong to the supported timing list and could be judged by sync polarity only.
At the meantime, real entered frequency of the supported timing is not requested exactly.
Normalization of VGA card’s deviation will be acceptable.
• Horizontal Frequency 24KHz ----80KHz
• Vertical Frequency 49Hz ------75Hz
