Display modes

The display modes and monitor uses are controlled by the computer. Therefore, refer to your computer documentation for details on how to change display modes.

The image size, position, and shape may change when the display mode changes. This is normal and the image can be readjusted using the monitor controls.

To ensure flicker-free operation, select the highest (non-interlaced) refresh rate that both the computer and the monitor can support, (generally 75 Hz or higher), for the addressability that your application requires.

For the display modes listed below, the screen image has been optimized during manufacture.

Resolution	Refresh Rate	Horizontal Frequency
640 x 480	60Hz	31.5kHz
720 x 400	70Hz	31.5kHz
1024 x 768	85Hz	68.6kHz
1280 x 1024	85Hz	91.1kHz
1600 x 1200	85Hz	106.3kHz
1920 x 1440	75Hz	112.5kHz
1920 x 1440	85Hz	128.5kHz
2048 x 1536	75Hz	120.5kHz

Power Management

To benefit from power management, the monitor must be used in conjunction with a computer that implements the Video Electronics Standards Association (VESA) Display Power Management Signalling (DPMS) Standard.

The power management feature is invoked when the computer recognizes that you have not used your mouse or keyboard for a user-definable period of time. There are several states described in the table below.
