Preset and User Modes
This monitor has factory preset modes for the most popular
industry standards for true “plug and play” compatibility.
When a new input signal is entered, the monitor selects the
appropriate factory preset mode and momentarily adjusts
the phase calibration to provide a high quality picture to the
center of the screen. The calibration is stored in memory
and is immediately recalled whenever the same input signal
is received.

Technical Features
For input signals that do not match one of the factory preset
modes, the digital Multiscan technology of this monitor
performs all of the adjustments necessary to ensure that a
clear picture appears on the screen for any timing in the
monitor’s frequency range. However, it may be necessary
to fine tune the vertical/horizontal size and centering.
Simply press the ASC button or adjust the monitor
according to the adjustment instructions. The adjustments
are stored automatically as a user mode and recalled
whenever the corresponding input signal is received.
Recommended horizontal and vertical timing
conditions
Horizontal sync width duty should be: >4.8% of total horizontal
time.
Horizontal blanking width should be: >2.5 µsec.
Vertical blanking width should be: > 450 µsec.
Note for Windows users
For Windows users, check your video board manual or the utility
program which comes with your graphic board and select the
highest available refresh rate to maximize monitor performance.
Adjusting the monitor’s resolution and color
number
