The Datacolor Spyder4 Express monitor calibration tool marries straightforward operation with extensive display compatibility. It can be used with standard LCD, LED and wide-gamut displays, and OLED panels and iPhones and iPads. The Spyder4 incorporates a seven-colour sensor, which promises more accuracy over the Spyder3, while double-shielding over the colour filters is said to stop colours changing over time.
