Multi‐Display Hardware Acceleration settings determine advanced rendering
options when using multiple displays and/or graphics cards based on different
classes of NVIDIA GPUs. The settings are shown in Figure 7.4.
Note: Multi‐display hardware acceleration options do not apply when using
• 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.
• 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.

When this mode is in effect, OpenGL renders in "performance" mode for all displays.
As in "compatibility" mode, when different classes of GPUs are in use, the lowest
common feature set of all active GPUs is exposed to OpenGL applications. However,
the rendering performance is "faster" than in compatibility mode, although
switching or spanning displays may result in minor transient rendering artifacts.
