ListVCGT
Monitor profiles for loading the LUT of a graphics card contain a VCGT tag with the LUT values. The VCGT tag contains hexadecimal values in the so-called big-endian format. Such data is hard to understand and thus needs to be converted into decimal numbers.
ListVCGT simplifies this task. The program window is almost identical to ListGammaRamp.
After starting ListVCGT, click on "Select Profile" and select the ICC / ICM profile of choice. The initial folder path is the path to the folder in which Windows stores the profiles. If you select a profile that does not contain a VCGT tag, an error message is displayed. Otherwise, the VCGT tag values of the selected profile are displayed exactly in the same way as in ListGammaRamp.
If you click on "Export Data", the data will be written to a CSV file. You can choose the folder and file name where to store the CSV file. The CSV file can be opened in a spreadsheet program, where a line chart can be created to visualize the data.
The downloaded installer file contains the 32-bit as well as the 64-bit version of ListVCGT. The installer automatically installs the right version matching the installed Windows version.
