GeForce 9800 GTX Features

Backed by NVIDIA's Lumenex Engine, the GeForce 9800 GTX delivers true 128-bit floating point high dynamic range (referred to as HDR), lighting capabilities with up to 16x full-screen anti-aliasing. Second-generation NVIDIA PureVideo HD technology with HDCP compliance delivers the ultimate high-definition video viewing experience to the Foxconn GeForce 9800 GTX Standard OC Edition video card 9800GTX-512N.

With hardware decoding for Blu-ray and HD DVD formats, PureVideo HD technology lowers CPU utilization when watching high-definition video formats by decoding the entire video stream in the graphics processor, freeing up the processor for other tasks. In addition to low CPU utilization, PureVideo HD enhances standard definition video content with de-interlacing and other post-processing algorithms to ensure standard DVD movies look their best on the PC screen and high-definition television sets. High definition content protection, or HDCP, technology ensures a secure connection between the GeForce 9800 GTX graphics card and an HDCP capable monitor for viewing protected content such as high-definition Blu-ray or HD DVD movies.

Coupled with PureVideo HD technology, the 9800 GTX deliver the ultimate multimedia experience. HDMI technology allows users to connect PCs to high-definition television sets with a single cable, delivering high-definition surround sound audio and video with resolutions up to 1080p. PureVideo HD technology scales video in the highest quality up to resolutions of 2560x1600 - from standard and high-definition file formats - while preserving the details of the original content. PureVideo HD technology also accelerates high-definition video decode, freeing up CPU cycles while watching high-definition Blu-ray and HD DVD movies or other VC-1 and H.264 encoded file formats.

NVIDIA PureVideo HD Technology

Along with world-class video acceleration, PureVideo HD has been at the forefront of advanced video post-processing. With the R174 series driver, we are introducing new features for PureVideo HD for GeForce 9800 GTX. These new features, Dynamic Contrast Enhancement and Dynamic Blue, Green, and Skin Tone Enhancements, are extremely computationally intensive and not found on even the most high-end Blu-ray or HD DVD players. But by tapping into the enormous pool of computational power offered by our processor cores, we can now enable post-processing techniques that have yet to be realized in fixed-function video processors.

• Dedicated on-chip video processor
• High-definition H.264, VC-1, MPEG2 and WMV9 decode acceleration
• Advanced spatial-temporal de-interlacing
• HDCP capable3
• Spatial-Temporal De-Interlacing
• Noise Reduction
• Edge Enhancement
• Bad Edit Correction
• Inverse telecine (2:2 and 3:2 pull-down correction)
• High-quality scaling
• Video color correction
• Microsoft Video Mixing Renderer (VMR) support

Advanced Display Functionality

• Two dual-link DVI outputs for digital flat panel display resolutions up to 2560x1600
• One dual-link DVI outputs for digital flat panel display resolutions up to 2560x16004
• Dual integrated 400MHz RAMDACs for analog display resolutions up to and including 2048x1536 at 85Hz
• Integrated HDTV encoder provides analog TV-output (Component/Composite/S-Video) up to 1080i resolution
• NVIDIA nView multi-display technology capability
• 10-bit display processing

Dynamic Color Enhancement

By analyzing the color components of each frame, we can also isolate and improve the appearance of blue, green, and skin tones, which the human eye is particularly sensitive to. Unlike televisions which have built-in image processors, PC monitors typically display the input picture without any processing, which can result in comparatively dull images. Dynamic blue, green, and skin tone enhancement alleviates this problem by applying correction curves on these sensitive colors. The result is improved total balance and clarity, without over saturation.
