4.5 Video Mode

Click the Video Mode button at the top of the GUI to display the Video Mode panel. Within this panel, there are two tabs:

DLPC900 Video Mode Panel - Source Settings Tab Figure 4-4 Video Mode Panel - Source Settings Tab
  1. Input Configuration.
    • Source Select – Allows the user to select:
      1. Parallel RGB interface
      2. Internal test pattern generator
      3. Pattern images from flash memory
      4. 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, swapping the order of the color channels is necessary. 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.
  2. 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.
  3. 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.
  4. Port Config Controls – Depending on which input signals were chosen during board design, selecting the appropriate signals is necessary so that the DLPC900 can properly detect the incoming video source. If incorrect settings are chosen, then the curtain is displayed or the image is 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 results in erratic behavior.

  1. Internal Test Pattern Color – When the internal test pattern is selected as the input source, the foreground and background colors can be changed.
  2. Display Dimensions – Allows the user to scale or crop the image of the incoming video source.
  3. 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.
