You can change the display resolution of your Mac to enlarge or increase the text size. Some pre-defined scaled resolutions are available, but you can get more granular control over your screen resolution.
Normally, a Mac will use its resolution at the resolution recommended by Apple. There are also four or five different options (depending on your Mac and the display and highlights below) that provide different options. the results. That's fine, but these are options to enlarge the text or enlarge your desktop without using the digital resolutions that we all understand. But if you do research, you can get real control on your screen by making real resolutions available to you.
Why is the display resolution important?
The resolution of a screen is the number of pixels available horizontally and vertically. A 4K screen has a resolution of 3840 x 2160 pixels or 3840 pixels horizontally and 2160 pixels vertically.
The amount of information you can see on the screen at any given time is governed by its resolution. Higher resolutions mean that more things can be displayed on the screen. These elements can be windows, icons, photos or text in a document. However, because of the wider resolution, it also means that all the elements on the screen are smaller, which is another thing to consider.
Larger screens also generally have higher resolutions than smaller ones, especially if they are of good quality.
What is the retina, the retina?
The direct link between the number of pixels on a screen and the space available on the screen is interrupted by Apple's use of Retina displays. Apple sets a Retina display as a screen with a pixel density so high that your eyes can not see individual pixels when sitting at a reasonable viewing distance.
For you, it means a clear image. And that's also where scaling comes into effect.
The 27-inch 5K printer with a resolution of 5120 x 2880 perfectly illustrates how Retina displays change our resolution resolution. You would expect everything to be tiny at this resolution, but because macOS enlarges it, it is not. Everything looks great thanks to the high resolution, but thanks to its scalability, you can always read it.
Scaling works by taking something that would typically use a single pixel and making it use multiples of two. This makes it possible to use a larger display resolution without reducing the elements on the screen to the point of being difficult to see. This also gives you the option to use a screen native resolution always.
Some scaling options are made available by default and they do their job. But they are vague and there is a way to select a more precise resolution.
Why choose a resolution can be important
If you need to know exactly what resolution you are using, the scaled options will not cut it. Some applications and games may require the use of specific resolutions, for example.
When you select a specific resolution, the number of available options is greater than that offered by your Mac. This can be very useful if you have special needs that are not usually taken into account.
How to select a specific resolution
You may want to fully control the display resolution of your Mac. You can override the macOS scaling and return to the old resolution-to-size ratio.
Click on the Apple logo at the top of the screen and then on "System Preferences."
Click on "Displays".
The Displays preferences panel has four scaling options, but no real resolution. Hold down the Option key and click "Scaled" to see them.
Click on a resolution to apply it.
Your Mac's display will refresh and you can close System Preferences.
