Datapixx(‘SetVideoMode’ [, mode=0]);
Set Datapixx video processing mode.
The Datapixx inputs digital DVI data, and outputs analog video. The video “mode”
determines how the digital data is converted to analog RGB. mode can take on one
of the following values:
0: C24, Straight passthrough from DVI 8-bit RGB to VGA RGB.
1: L48, DVI RED[7:0] is used as an index into a 256-entry 16-bit RGB
color lookup table.
2: M16, DVI RED[7:0] & GREEN[7:0] concatenate into a VGA 16-bit value sent to
all three RGB components. This mode also contains a 256-entry color lookup
table overlay indexed by the blue component. Set the blue component to 0
to allow the 16-bit monochrome data to show through.
3: C48, Even/Odd pixel RED/GREEN/BLUE[7:0] concatenate to generate 16-bit RGB
components at half the horizontal resolution.
5: L48D, DVI RED[7:4] & GREEN[7:4] concatenate to form an 8-bit index into a
256-entry 16-bit RGB color lookup table.
6: M16D, DVI RED[7:3] & GREEN[7:3] & BLUE[7:2] concatenate into a VGA 16-bit
value sent to all three RGB components.
7: C36D, Even/Odd pixel RED/GREEN/BLUE[7:2] concatenate to generate 12-bit
RGB components at half the horizontal resolution.
8: RB24, DVI RED[7:0] & GREEN[7:4] concatenate to form 12-bit RED value,
DVI BLUE[7:0] & GREEN[3:0] concatenate to form 12-bit BLUE value,
GREEN is forced to 0
