Display Resolution Display Resolution
Indicates the current resolution being used by your monitor. Not all of
the resolution settings supported by your monitor necessarily offer
accelerated 3D performance. For a list of resolutions supported by your
Oxygen card, refer to the
Monitor Resolution Tables on page 38.
Pixel Depth Pixel Depth
Identifies the number of color planes (known as bits) stacked on top of
each other to create a pixel. If the pixel depth is 16-bit, then Oxygen
displays five bits each of red, blue and green and a one-bit overlay, for
a total of 32,768 colors.
Z-buffer Depth Z-buffer Depth
Specifies the bit depth of the Z-buffer. Oxygen cards support 16-bit
and 24-bit Z-buffers. Using a Z-buffer provides added realism to a
scene by modifying the positioning and visibility of pixels as a function
of distance.
Refresh Rate Refresh Rate
The rate at which your monitor repaints the displayed image from the
top of the screen to the bottom. Oxygen cards support multiple refresh
rates for each resolution, but a refresh rate of at least 75Hz is
recommended.
Installed Oxygen Cards Installed Oxygen Cards
Refers to the number of Oxygen cards installed in your system. Oxygen
supports dual displays if you have two identical Oxygen cards installed
in your system; however, you must enable dual monitor mode, which
is found on the
Advanced Options page.
