In Standby mode, the monitor (and other devices) are switched to a reduced-power state if
you do not use your mouse or keyboard for a specified period. The devices remain in a
state of readiness and return to full power if you press a key or move the mouse. Suspend
further decreases monitor power, and Off reduces monitor power to its lowest level. Refer
to “Advanced Power Management” on page 42 for more information on power
management.
Check the documentation that comes with your monitor to see if your monitor is enabled
for power management. If you find no information about power management, your
monitor probably does not support this feature. If your monitor does not have DPMS
support, deactivate it in the power-management features of your software or use the
Configuration/Setup Utility Program to disable Display in all three levels of power
management. Even if you deactivate the display for power-management purposes, you can
still take advantage of screen savers. Refer to “Using Screen Savers” on page 15 for more
information.
Selecting a Monitor
The graphics controller installed in your computer is a high-performance, high-resolution
graphics accelerator and includes many performance-enhancing features for your operating
system environment. It has a built-in monitor connector. See “Video Control” on page 15
for more information. The graphics controller supports various SVGA monitor resolutions.
If you connect an SVGA monitor to your computer, you can take advantage of SVGA
resolutions such as 1024 x 768. However, the default resolution might be different for
certain software packages, especially if they are not SVGA-ready. Also, you might have to
install device drivers for certain software packages. Refer to the device-driver installation
instructions that come with the software on the IBM Software Selections CD for a list of
programs and the device drivers that they require.
To take full advantage of the video capabilities provided by your computer, use a
noninterlaced monitor capable of supporting high resolution and a fast refresh rate. Also,
the type of monitor you select depends on the software you use. Some applications are less
demanding than others.
Using Monitor Controls
A monitor has brightness and contrast controls for adjusting the image on the monitor
screen for maximum viewing comfort. On a new monitor, set the controls near their center
positions. Setting these controls to their maximum positions can decrease the useful life of
the monitor. As the monitor is used more, the image tends to become dimmer. You can
adjust the brightness and contrast controls to compensate for this condition. Monitors also
have additional controls for fine-tuning the screen image. Check the documentation that
comes with your monitor for more information on controls.
