I'm tired of my monitors and phones all looking different. I tried following instructions at Lagom LCD monitor test pages, but they still look different. So, I think I need to buy something to help make them look the same.
Reading on the DisplayCAL site, I see that there are over 20 colorimeters and spectrometers. I don't know the difference between them. How do I find the difference so I can choose the right one?
The cheapest device I see is Spyder2, but what makes it different from devices that cost more? How do I know if they're worth the higher price?
