Barco MFGD 3621, MFGD 2621 user manual Enable Dithering

BarcoMed control panel operation

while maintaining compatibility with the Windows graphics device interface (GDI). DirectDraw is enabled by default.

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.
