The X-Rite i1Display Pro is a calibration and profiling system for a display / projector. It helps to make sure that the colors on your display match those in your original picture or file. The i1Display features i1Profiler software for calibrating and profiling all modern display and projector technologies, including LED and Wide Gamut LCDs. It's also spectrally calibrated, which makes it field-upgradeable to support future display technologies. Using the free and downloadable ColorTRUE app for iOS and Android, the i1Display Pro may also be used to calibrate select phones and tablets.
