Summary
Brightness and contrast are two self-explanatory display tweaks and are pretty easy to configure.
However, you might have noticed a mysterious third setting called “gamma.”
This article will explain everything you should probably know about gamma and what to set it to.

What Is Gamma?
This might sound confusing, so let’s look at a practical example.
Let’s say you took two identical lamps and placed a random object in front of them.
When you turn one lamp on, the object will be illuminated.
However, a camera can capture that difference in luminance quite effectively.
Why Is Gamma 2.2 the “Standard” Setting?
Gamma 2.2 provides the most accurate, true-to-life visual representation.
It’s the value scientists and engineers landed on after extensive research and testing.
Here’s a comparison of gamma 2.0, 2.2, and 2.4.
The original image with gamma 2.2 is in the middle.
That’s why images are often edited to look nicer across all displays.
This is perfect if you like to fine-tune your display.
Subjectivity plays a massive role in gamma.
What Should I Set My Gamma To?
Generally speaking, the standard gamma 2.2 should look the best across the board.
This applies to video games, movies, pictures, videos, and even website color schemes.
Other gamma values might look better under certain circumstances, though.
If you’re in a dark room and have a bright display, gamma 2.4 can look great.
Gamma is the least understood but most interesting setting on our displays.
