Using video features

Your computer has a PCI Express x16 graphics adapter that renders 2D or 3D
image quality and uses a standard video protocol for displaying text and graphic
images on a monitor screen. The adapter supports a variety of video modes
(combinations of resolution, refresh rate, and color that are defined by a video
standard for displaying text or graphics).

Video device drivers

To use the full capabilities of the graphics adapter in your computer, some operating
systems and application programs require custom video device drivers. These
device drivers provide greater speed, higher resolution, more available colors, and
flicker-free images.
Device drivers for the graphics adapter and a readme file with instructions for
installing the device drivers are provided on the Device Drivers CD that comes with
your computer and in the c:\ibmtools\drivers directory on the hard disk. Use the
device-driver installation instructions if you have to reinstall the device drivers or if
you need information about obtaining and installing updated device drivers. For
more information about installing device drivers, see "Recovering or installing device
drivers" on page 82.

Changing monitor settings

To get the best possible image on your screen and to reduce flicker, you might have
to reset the resolution and refresh rate of your monitor. You can view and change
monitor settings through the operating system by following the instructions in the
readme files on the Device Drivers CD or in the c:\ibmtools\drivers\ directory on the
hard disk. See your operating-system documentation for more information about
monitor settings.
Attention:
comes with your monitor. Using a resolution or refresh rate that the monitor does
not support might cause the screen to become unreadable and could damage the
monitor. The information that comes with your monitor usually includes resolution
and screen refresh rates that the monitor supports. If you need additional
information, contact the manufacturer of the monitor.
If you are using a cathode ray tube (CRT) monitor, set your monitor for the highest
noninterlaced refresh rate that the monitor supports. If the monitor complies with the
Video Electronics Standards Association (VESA) display data channel (DDC)
standard, it is probably already set to the highest refresh rate the monitor and video
controller can support. If you are not sure whether your monitor is DDC-compliant,
see the documentation that comes with the monitor.
If you are using a flat-panel monitor, the refresh rate does not have to be set to the
highest noninterlaced refresh rate that the monitor supports. Flat-panel monitors
produce flicker-free images even when they are operating at a minimum 60 Hz
noninterlaced rate.
Before changing monitor settings, review the documentation that
