Answer: "Hard calibration" is a form of hardware calibration that fine tunes the color and brightness for specific LED modules on the DVLED Display.
Situations in which hard calibration may be required:
- LED Module position is changed or LED Module is replaced with a spare,
- LED Modules from a different color batch need to be used,
- LED Modules on the display have been used for a long time (>1 years) and need to be replaced with spare LED Modules
Please be aware that equipment like a professional camera will be needed for this process. Hard Calibration should only be done by trained professionals. Trained professionals may contact LD BU for the full Hard Calibration Training procedures.
