Configuring Key ForceWare Graphics Driver Features
• Single-display mode: If you have only one active display, this is the default
setting. You can also specify this setting if you have problems with the multi-
device modes.
• nView Clone/Span mode is the default setting when your nView display mode is
set to nView Clone mode or one of the nView Span modes. If multiple NVIDIA-
GPU based graphics cards in your system are in use with active displays, this
setting is replaced by one of the “multi-display” modes described below.
Figure 7.10 Hardware Acceleration Driver Setting
• Multi-display compatibility mode is available if you have two or more active
displays when running in nView Dualview display mode or if you are using
different classes of NVIDIA GPU-based cards.
Note: When this mode is in effect, OpenGL renders in “compatibility” mode for all
displays. In this mode, when different classes of GPUs are in use, the lowest
common feature set of all active GPUs is exposed to OpenGL applications.
The OpenGL rendering performance is slightly slower than in single-
display mode.
• Multi-display performance mode is available if you have two or more active
displays when running in nView Dualview mode or if you are using different
classes of NVIDIA GPU-based cards.
