True Tone
The new iMac also gets a nice display improvement that users of MacBooks and iPads actually take for granted these days: True Tone display technology.
This means that you can now ensure that the colours you see on your screen are properly balanced for the ambient lighting in your room. While it was always possible to do this manually by fiddling with the colour settings (which may have been one reason Apple felt True Tone wasn’t as necessary on a stationary desktop iMac), the True Tone feature means that you don’t have to do this, nor do you have to guess if you’ve gotten it right. It’s going to be a big boon if you do any kind of photo or video editing on your iMac.
