Display Resolutions and Settings

A monitor that supports 1024x768 resolution at 75 Hz vertical refresh
rate is the minimum recommended for use with Oxygen. Choose a
resolution, number of colors, and refresh rate that is high enough to
meet the needs of your graphics application as well as your personal
preference. Performance will vary at certain settings due to the amount
of frame buffer memory available.

The following tables detail the 3D display settings supported by your
Oxygen card. The first column lists resolution, measured in pixels. The
second column contains bit depth information. Bit depth is another
way of expressing the number of colors available. A color bit depth of
16 colors (15 bits of color plus a 1-bit overlay) yields 32768 colors, and
a bit depth of 32 (24 bits of RGB plus 8-bit overlays) equals 16.7 million
colors. The latter is often referred to as “true color”. The third column
indicates the depth of the Z-buffer. In a few cases, 3D graphics are not
accelerated and the graphics are instead drawn in software through the
GDI interface. The final column lists the refresh rates supported.

NOTE: Please be aware that when you change resolutions, you should
not use the “

Test” button in the Display Control Panel. Selecting this

button may cause a blue screen. If a blue screen occurs, please reboot
your system.
