Datacolor Spyder is a paid display-calibration product for professional photographers and advanced photo editing. Its hardware sensor connects through USB-C, with a USB-A adapter included, while software calibrates LCD, mini-LED, OLED and QD-OLED monitors, including Apple XDR and Liquid Retina displays. Room Light Monitoring measures the room’s light and can warn when recalibration is needed or adjust profiles automatically according to the light level. DevicePreview shows how photos may appear on mobile devices while they remain on the calibrated monitor. A full-screen comparison shows the display before and after calibration, with 11 brightness settings. The comparison table lists unlimited supported displays, subject to computer capability. Spyder supports Windows 10 or 11 and macOS 10.14 through macOS 26, and requires internet access for downloading and activating the software. It calibrates monitors only, not phones or tablets. The listed price is $169 as a one-time purchase.
