# Calibration d'un écran

You can callibrate your screen so that it shows more accurate colour. This is especially useful if you are involved in digital photography, design or artwork.

You will need either a colorimeter or a spectrophotometer to do this. Both devices are used to profile screens, but they work in slightly different ways.

Open the Activities overview and start typing Color.

Click on Color to open the panel and select your screen.

Make sure your calibration device is connected to your computer.

Press Calibrate… to commence the calibration.

Screens change all the time: the backlight in a TFT display will halve in brightness approximately every 18 months, and will get yellower as it gets older. This means you should recalibrate your screen when the [!] icon appears in the Color panel.

Les écrans à LED évoluent aussi dans le temps, mais dans une bien moindre mesure que les TFT.
