![]() Unfortunately, you cannot use any other hardware or software for true hardware LUT calibration. They require the X-Rite i1 Display Pro hardware and specific Dell UltraSharp Color Calibration software. The Dell U2413 / U2713H and U3014 monitors have a very specific process for hardware calibration using the LUT. Please note that the factory-calibrated AdobeRGB and sRGB profiles are different and might not be as accurate, especially after several months of use. This allows calibrating the U2413 for several color spaces such as AdobeRGB and sRGB. With the Dell U2413, for example, one can calibrate two separate user-selectable preset modes: CAL1 and CAL2. Depending on the monitor type / model, several combinations of color calibration are possible. Compared to software, hardware calibration is much more accurate and there is no need to modify color output through the graphics card. Brightness, contrast and color levels are automatically adjusted by the monitor through calibration software. ![]() Hardware calibration, on the other hand, generates a Look Up Table that is written into the monitor to map all the colors. During the calibration process, calibration software will usually ask to adjust brightness, contrast and color levels on the monitor, if such options are available. Thus, most monitors on the market today would be calibrated via software. Software calibration is usually performed on monitors that do not have the LUT capability (very few do). Software calibration works by modifying the colors via the computer graphics card and loading those colors every time the operating system boots. There are two types of calibrations available for monitors – software and hardware.
