while maintaining compatibility with the Windows graphics device 
interface (GDI). DirectDraw is enabled by default.
More information about DirectDraw is available through the on-line 
help.
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.
More information about Dithering is available through the on-line help.
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 or BarcoMed Coronis 
or example, run in extended depth (10-bit) mode by default.
Implications
When turned on the “Disable 10-bit grayscale” 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.
