Spyder5 is the previous generation of Spyder hardware and technically a totally different piece of hardware compared to the new Spyder X sensors, even if they look similar shape wise.

Our new lens-based technology provides a higher level of color accuracy with more precise screen color, shadow detail and white balance. Calibrate your monitor in 1 – 2 minutes.
