Color Calibrator For Monitor and Tv

Hello guys,

I Recently bought the X-Rite i1Display Pro - Display Calibration (EODIS3) on Amazon, wondering if anyone here has used color calibrators for their screens and how good are they. To be honest I bought because I just got an LG 50" 4k Tv where I'm playing most of them third person games and a Acer Predator X34 for FPS and other games. I'll post some photos of my setup once I'm done with a couple of upgrades and cosmetic fixes on my Pc. So anyways, any input on this would be great.

Cheers.

@robertoenrique: They're extremely accurate. Use the included software for your monitor and hcfr if you want to calibrate a tv not connected to a pc.

i1d3 is an excellent colorimeter and because it's sealed doesn't deviate over time as much as original i1.
