B.1 Compatibility of VESA Timing
The LCD monitor is capable of accepting both the traditional analog RGB video sig-
naling and the new digital DVI (Digital Visual Interface) signaling.
Due to its digital design and the implementation of this new digital standard interface,
setting frequency mode is not necessary for a user and it will be handled automati-
cally between the monitor and the digital graphic card adapter. For analog input, the
LCD monitor operates at horizontal frequencies between 35.1 kHz and 80 kHz, verti-
cal frequencies between 56 Hz and 75 Hz. Because of its microprocessor-based
design, it offers auto-synchronization and auto-sizing capabilities.
This monitor offers 21 pre-programmed VESA monitor timing that are listed in the fol-
lowing Table B.1. These preset modes cover most of the common video modes sup-
ported by popular graphics adapters. However, each adapter’s implementation of
these video modes may vary slightly in timings.
