Procedure

  1. Next to Dither Enable, select Enable to enable the dither submodule of LTM.
  2. Next to Dither Config, click View/Edit this Table to edit the dither tables for R, G, and B channels.
    The dither table for each channel contains a value for low array and a value for high array.
    You can use one of the following methods to update the Dither Config table:
    • Double-click and edit a cell in the table to update a single value.
    • Click Edit and update the values in the prompted Edit Table dialog.

      The values must be specified in the same order as the table columns and separated by a comma (,).

    • Click Export to export the values to a .csv file, edit the file, and then import the updated values from the .csv file.

      The order of the values in the exported .csv file is the same as that in the table.

Results

  • The tuning results are printed in the Console view in real time.
  • The image displayed on the VTunerServer side is updated.
