Limitations in This Release
The following are features that are not currently supported or have limited
support in this driver release:
• Refresh Rate Precision
The current driver programs the hardware timing for a 59.94 Hz refresh rate
to be the same as the timing used for a 60 Hz refresh rate.
• Pan & Scan
This driver does not support the Pan & Scan feature. (Pan & Scan is the
process of panning across the desktop in order to display a desktop on a
monitor with lower resolution).
• DirectX Antialiasing
The NVIDIA Control Panel does not offer full antialiasing support for
DirectX applications. NVIDIA Control Panel antialiasing should be set to
Application-controlled to ensure compatibility with all DirectX applications.
• Full-featured HDMI Support
The following are known problems that will be fixed in a future driver
version:
• There are some known image quality issues.
• Noise and pixel corruption occur under Clone or Dualview modes.
• Only stereo audio is supported; 5.1 surround is not supported.
• INF Support for Restricted Timings
This driver version does not support the use of Restricted Timing settings
(R&T strings) in the INF to control mode validation and/or mode setting for
custom mode/adapter/monitor combinations. This capability is planned for
a later driver release.
• Display rotation
The NVIDIA Control Panel does not include display rotation controls.
• Overscan/Underscan Support
The ability to display the entire desktop on a TV is not supported—the
desktop will be masked instead.
• Advanced Timings, Custom Resolutions
This driver does not support adding arbitrary resolutions and timings.
• Mode Filtering for Custom Policies
This driver does not support defining advanced timings and resolution
settings.
• SDI
This driver does not support the Serial Display Interface (a standard for
driving high color depth displays).
• Genlock/Frame Lock
This driver does not support the ability to synchronize multiple display
outputs with an external signal.
• NVIDIA SLI Technology
This release is intended to serve as a functional preview for application
porting purposes, and not as a performance driver.
• NVIDIA TurboCache
The driver is capping Shared System Memory at 255 MB on systems with 1
GB of system memory, and at 271 MB on systems with 2 GB or more of
system memory. An upcoming driver will increase this amount of memory.
Optimum performance will not be achieved with low frame buffer
TurboCache graphics cards.
