ELECTRICAL CHARACTERISTICS
Scaler should be capable of below items.
1) Scaler must support color engine for Image enhancement feature (SmartImage)
2) Scaler must have enough memory to support PerfecTune feature and Philips OSD

4) VGA signal Auto adjustment:
Monitor automatically adjusts and optimizes resolution and frequency based on input signal defined by
"Source" function. "NO VIDEO INPUT" (source)"(Note A)message to be displayed on screen while no
signal is detected. Monitor will automatically optimize resolution and frequency whenever connected to
different signal source. When press the "Auto", the screen also show a status bar. During adjustment
period, a status bar will show on screen from 0% to 100% to indicate the progress of adjustment.
Auto auto adjustment : new timing & preset modes ( non- factory preset mode) should do auto
date into memory.
