I used Gamma to calibrate one of my monitors, and then I copied the created profile and used it on my other monitor. I opened two similar pictures on both monitors, and compared the appearance. They were a bit different from one another. Is this normal? Or should I calibrate monitors diffrently? Should calibrated monitors all have the same colors in the same pictures? Sorry, I'm pretty noob about this. XD

Each computer sends a unique video signal to each monitor. Which is why the ICC profile for each monitor is different even when generated by a colorimeter.

Why not read the other threads in this forum?

Perhaps you could start off with this one?
