Click the Video Mode button at
the top of the GUI to display the Video Mode panel. Within this panel, there
are two tabs:
- Input Configuration.
- Source Select –
Allows the user to select:
- Parallel RGB interface
- Internal test pattern generator
- Pattern images from flash memory
- Solid Curtain– which displays a constant, solid
color image (including black or white)
- Input Port Data
Swap – Depending on the routing of the parallel RGB data lines,
it may be necessary to swap the order of the color channels. The DLP
LightCrafter Single DLPC900 EVM require ABC->BAC setting. ABC
corresponded to RGB; therefore, the settings mentioned previously means
that channels RG are swapped. The user can also select which port to
apply the settings to.
- Pixel Data Format
– Allows the user to select the video format of the input source.
- Port Config Controls – Depending on which input signals
were chosen during board design, it may be necessary to select the appropriate
signals so that the DLPC900 can properly detect the incoming video source. If
incorrect settings are chosen, the curtain may be displayed or the image may be
incorrect. Pixel Mode can also be set to Single Pixel or Dual Pixel. Dual
Pixel allows for higher data rates by loading two pixels per clock instead of
one pixel per clock.
- IT6535 Receiver – This control allows selection between
the HDMI or the DisplayPort input connectors of the IT6535 digital receiver. The
digital receiver can also be powered-down, which tri-states all the output
signals of the IT6535 to allow another device to share the input ports and syncs
of the DLPC900.
- Pixel Port Configuration -
Allows readback of the current parallel port configuration parameters determined
by the EDID or user Display Dimensions
- Internal Test Pattern
Color – When the internal test pattern is selected as the input source,
the foreground and background colors can be changed.
- Display Dimensions –
Allows the user to scale or crop the image of the incoming video source.
- De-Gamma LUT Control –
De-Gamma controls:
- De-Gamma LUT Control –
De-Gamma controls:
- Enable/Disable - Command
enables or disables De-Gamma
- Sets the level of
De-gamma - See the Gamma Configuration and Enable section of the
DLPC900 Programmer's Guide for further
information.
