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 requires an RGB → GRB setting. The user
selects which port to apply the settings.
- 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.
Note: Only Pixel Clock 1 is connected on the DLPLCRC900EVM.
Selecting Pixel Clock 2 or 3 on the EVM will result in erratic
behavior.
- 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.
- Parallel Port
Configuration - Allows readback of the current parallel port
configuration parameters determined by the EDID or user Display Dimensions.
Values are read only from the primary controller.
- 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:
- 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
