Question about Calibrite i1Display Pro

Not directly with the software that comes with it. You need third party software that is compatible with the sensor (Lightspace, Calman, ...), and depending on how long it takes you to get used to it, some time and effort. Check out Lightspace DPS: it's pretty manual, but it's free.

I used it to calibrate the UE 65 H 8080. It gives a great picture, much better than the factory settings. But you still need software, I used Calman Enthusiast (if you still want to calibrate computer screens), otherwise Calman Control probably works too. But such software costs at least as much as the sensor.
