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.

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 horizontal/vertical 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

Adjust the monitor’s resolution and color number by referring to your computer’s instruction manual. The color number may vary according to your computer or video board. The color palette setting and the actual number of colors are as follows:

High Color (16 bit) n65,536 colors

True Color (24 bit) nabout 16.77 million colors In true color mode (24 bit), speed may be slower.
