Display modes

The display mode 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 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 optimised during manufacture.

Resolution	Refresh Rate	Horizontal Frequency
720 x 400	70Hz	31.5kHz
640 x 480	60Hz	31.5kHz
640 x 480	85Hz	43.3kHz
800 x 600	75Hz	46.9kHz
800 x 600	85Hz	53.7kHz
1024 x 768	75Hz	60.0kHz
1024 x 768	85Hz	68.6kHz
1280 x 1024	75Hz	80.0kHz
1280 x 1024	85Hz	91.1kHz
1600 x 1200	75Hz	93.8kHz

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 as described in the table below.

State	Power	Screen	Restoring Operation
	indicator
On (Active)	Green	Normal	Press a key or move the mouse.
Off (Sleep)	Amber	Blank
Switch Off	Off	Blank
