Datacolor offers three versions of the Spyder4: Express, Pro, and this range-topping Elite model. Not content with simply calibrating your monitor, this gadget will calibrate projectors as well as iOS and Android mobile screens.

Wide-gamut, LED-backlit and CRT monitors are supported, plus the device measures ambient light levels. Despite the advanced tech, this is still a doddle to use with well designed software, and those spidery legs keep the hardware resting nicely on your screen.

Our initial calibration was plagued by a blue colour cast, and though a software update cured the problem, the Spyder4Elite couldn’t quite match the colour accuracy of the competing X-Rite colorimeters. Calibration time: 5 minutes 15 seconds Colour accuracy after calibration (Delta-E, lower scores better): 0.77

This Spyder may only have three ‘legs’, but it’ll still sit comfortably on your monitor regardless
