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
3) Scaler must support SmartContras,20M:1 DCR preferred
4) VGA signal Auto adjustment:
Monitor automatically adjusts and optimizes resolution and frequency based on input signal defined
by "Source" function. "NO VIDEO INPUT" 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
