Monitor calibration is the process of adjusting a computer monitor's settings to ensure accurate color representation and brightness. This is important for tasks like graphic design, photography, and video editing, where precise colors are crucial. Calibration helps to align the monitor's output with standard color profiles, making sure that what you see on the screen closely matches the intended colors. To calibrate a monitor, users can employ hardware tools like a colorimeter or software solutions that guide them through the adjustment process. Regular calibration is recommended, as monitors can drift over time due to factors like aging components and environmental changes, affecting their performance and color accuracy.
