BarcoMed Driver Tab

note that this option is only available when the User Modifiable Palette
Mode is selected. This is because dithering is only supported under
Windows when the display is palletized. 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
regardless of whether this check box is checked. This complies with the
Windows standard interface method.
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 1MP2FH, 2MP2H, 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 “H” series 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.
