One of the features I use regularly in the display settings of OS X is the adjustment of the gamma setting of my monitor. This is useful because it can lighten up dark movies when you are watching them on your Mac. The gamma setting is only available in the “expert” mode of display settings which has disappeared in El Capitan. Thankfully expert mode is still there, it’s just hidden. To get into expert mode on El Capitan hold down the option key when you select ‘Calibrate…’ in display settings.
This is what you see when you open ‘Displays’ in your System Preferences in OS X. If you hold down the option key while you select ‘Calibrate…’ the box to select the hidden expert mode from previous versions of OS X will appear.
Now you can click in the expert mode box which will enable you to set the gamma settings.
You can use this setting to make dark movies appear brighter when you watch them on your Mac, although you will want to change the gamma settings back for normal work.
I did find gamma settings as you describe but I wish you did eplain more about what gamma adjustment is and how to set it up to lighten up dark movies
There is a separate article on that floating around on this website somewhere! Search under gamma or dark movies.
The iPhone 7S will act as the perfect bridge between the last generation iPhones that we saw till 2016 and the next level iPhone 8 that we are all looking forward to. But will we see the iPhone 7S and the iPhone 8 being released together, or a year apart as has been the norm up until now? Can’t wait for Apple to make an announcement!
