Unable to set LUTs Error With i1Profiler

Customers are unable to create and save their display profile with i1Profiler

The "Unable to set LUTs" error when trying to create a monitor profile may be caused by a combination of things. First, check to see if the computer display’s menu has "DDC" or "DDC/CI" enabled or turned on. If so, disable it or turn it off in the display’s menu. In addition, we would recommend turning off "ADC" (Automatic Display Calibration) if this error appears when profiling. Follow these instructions to turn "ADC" off:

  1. In the "Measurement" step, select the "Adjust brightness, contrast, and RGB gains manually". This will unselect "Automatic Display Control (ADC)"
  2. Uncheck the contrast or RGB options if those controls are not manually adjustable on the monitor.  DO NOT unselect the option to adjust brightness manually…this must remain selected.
  3. Click "Next" to save these settings and begin the profiling process.
  4. Create a new display profile.

There are some PC video cards that do not support LUTs (Look Up Tables).  If the aforementioned settings changes do not allow the profile to be created, consider the web article that includes a small test utility at the following link:  LUT Tester - How to determine Video card cpmpatibility.
