15USTechnical FeaturesPreset and user modesWhen the monitor receives an input signal, it automaticallymatches the signal to one of the factory preset modes stored in themonitor’s memory to provide a high quality picture at the centerof the screen. (See page 20 for a list of the factory preset modes.)For input signals that do not match one of the factory presetmodes, the digital Multiscan technology of this monitor ensuresthat a clear picture appears on the screen for any timing in themonitor’s frequency range (horizontal: 30 – 130 kHz, vertical: 48– 170 Hz). If the picture is adjusted, the adjustment data is storedas a user mode and automatically recalled whenever the sameinput signal is received.Note for Windows usersFor Windows users, check your graphics board manual or theutility program which comes with your graphics board and selectthe highest available refresh rate to maximize monitorperformance.Power saving functionThis monitor meets the power-saving guidelines set by VESA andENERGY S TAR.
