Introduction
3Dlabs Oxygen GVX420 User's Guide vii
Overview Overview Overview Overview
Your Oxygen GVX420 card has the following features:
• Seamless Dual-head support
Oxygen GVX420 supports dual high-resolution displays under Windows NT 4.0 and Windows
2000 from a single card, seamlessly supporting a total multi-monitor true-color desktop size of up to
4096 x 1536. The two VGA connectors and two DVI connector allow you to connect either two
VGA monitors, two DFP monitors, or one VGA monitor and one DFP monitor.
• Dual GLINT R4 rasterization processors
The dual GLINT R4 processors doubles rasterization performance for sustained productivity with
more textures and higher resolution screens.
• GLINT Gamma G2 geometry processing
On-board hardware geometry acceleration boosts the interactivity of large models by up to three
times and offloads the CPU for increased application performance. The 5Gflop new generation
GLINT Gamma G2 processes 100% of the OpenGL geometry pipeline in silicon, including 16
simultaneous light sources.
• Virtual Textures
Oxygen GVX420 implements 3Dlabs unique full demand-paged virtual texture sub-system in
hardware, using on-board graphics memory to cache up to 256MB of textures stored in main system
memory. Oxygen GVX420 allows you to manipulate up to 256MB of textures, seamlessly from your
favorite applications.
• PowerThreads SSE OpenGL Drivers
3Dlabs’ new-generation PowerThreads SSE and 3DNow! OpenGL drivers are fully optimized for
Pentium III and Athlon processors to dynamically load balance the geometry and lighting load
between the GLINT Gamma hardware geometry processor and host CPU. PowerThreads SSE and
3DNow! give you the power of geometry hardware plus the additional power of Pentium III’s SSE-
instructions or Athlon's 3DNow! instructions for full performance scalability with faster host CPU’s.
• Dynamic load balancing
When the GLINT Gamma processor is busy, geometry and transform calculations are automatically
shared between the CPU and the GLINT Gamma.
• High-resolution Digital Flat Panel Output
The Oxygen GVX420 is pre-configured with a factory-installed daughter card that provides support
for digital flat panel displays through two Digital Video Interface (DVI) connectors. The daughter
card provides improved on-screen image quality at resolutions up to 1280 x 1024 on two monitors.
• Quad-buffered stereo
Left and right buffers are flipped simultaneously to preserve synchronization in your stereo 3D
images at resolutions up to 1280 x 1024.
• 128 MB memory
128 MB of SGRAM memory supports high-precision, high-performance acceleration.
• High-precision, high resolution display
Your Oxygen card has dual 300 MHz RAMDACs enabling flicker-free resolutions up to 2048 x
1536 on a single monitor or 4096 x 1536 with two monitors connected.
