Enable Dithering
This option allows the user to enable or disable dithering. Dithering is
a technique for increasing the perceived range of colors in an image
at the cost of spatial resolution.
Note:
This option is only available when the
User Modifiable
Palette
mode is selected. If either the
Static Gray Palette
including Standard System Colors
mode or the
Static Gray
Palette with NO System colors
mode is selected, the “Enable
Dithering” check box will be grayed-out, and dithering will be
automatically disabled.
Disable 10-bit grayscale
Use this option for standard Windows®-based applications that
require 8-bit color support (256 colors), such as Internet Explorer,
Excel, etc.
Do
not
use this option for applications that require 10-bit pixel
support (1024 simultaneous shades of gray) and use extended depth
graphic libraries such as WinBarco.
Description of 10-bit grayscale:
To show 1024 simultaneous
shades of gray all BarcoMed “H” series display controllers, such
as the BarcoMed 5MP2FH, BarcoMed Coronis or BarcoMed
Coronis 5MP for example, run in extended depth (10-bit) mode
by default.
Implications:
When turned on the “Disable Extended Depth”
option causes a BarcoMed Coronis display controller to run in
8-bit mode, which results in increased performance since the
frame buffer is set to run with 8-bit pixels. While this option may
be used with applications that normally require 10-bit support,
there will be a loss of pixel depth, i.e. 256 shades of gray
instead of 1024 simultaneous shades of gray.
