Display scaling makes your Mac’s interface size more comfortable on non-Retina displays, but incurs visual and performance penalties. We explain these effects and their importance.
In a world where Apple’s idea of display resolution is different from that of the PC monitor industry, it’s time to understand how these two standards meet and merge on your Mac’s desktop.
A bit of Mac-sol…
Apple introduced the Retina display on the Mac with the 13-inch MacBook Pro on October 23, 2012, with four times the pixel density. From then on, Apple gradually introduced the Retina display to all of its Macs with built-in displays.
That was great, but it turned out that Apple had discontinued manufacturing its standalone monitors, leaving that task to LG in 2016. So if you needed a standalone monitor or a second monitor, officially switch to Retina was not an option.
However, Apple has now re-entered the external monitor market and you must decide whether to pair your Mac with a Retina display, such as the Pro Display XDR or Studio Display, or another non-Retina option.
And part of that decision depends on whether you’re concerned about matching the macOS resolution standard.
Enter display scaling
Quadrupling the pixel density of a display presents a problem: if you don’t adjust anything, all UI elements will be four times smaller. This makes the visualization uncomfortably small. So when Apple introduced the Retina standard, the user interface also increased fourfold.
The result is that macOS is designed for a pixel density of 218 ppi, which Apple’s Retina monitors deliver. And if you deviate from it, you run into compromises.
For example, take the Apple Studio Display, which measures 27 inches. It has a resolution of 5120 x 2880, so macOS will double the horizontal and vertical dimensions of the UI, thus making your desktop the equivalent of 2560 x 1440. Since macOS was designed for this, everything appears at its intended size .
Then consider connecting a 27-inch 4K monitor to the same Mac. This has a resolution of 3840 x 2160, so the same scaling factor of 2x will result in an interface size equivalent to 1920 x 1080.
Since 5K and 4K screens are physically the same size with the same scaling factor, 4K’s lower pixel density means everything will appear larger. For many it makes it uncomfortable big visualization.
The difference between native scaling and display scaling on a 4K monitor.
If you go to System Parameters — > Attach, you can change the scale factor. However, if you scale it down to the equivalent of 2560 x 1440 on a 4K monitor, macOS calculates the scaling differently because 3840 x 2160 divided by 2560 x 1440 is 1.5, not 2. In this case, macOS renders the screen at 5120 x 2880 for a virtual buffer, then scales it down by 2 x to reach 2560 x 1440.
Display scaling – this method of rendering the screen at a higher resolution and then scaling down by 2x – is how macOS can render smoothly at many different display resolutions . But it comes with a few caveats.
Macular degeneration
Applying a 2x scaling factor to the respective native resolutions of a 5K monitor and a 4K monitor will result in a pixel-perfect image. But display scaling will render a 2560 x 1440 image on a 3840 x 2160 screen. This will naturally produce visual artifacts, as it is no longer a 1:1 pixel mapping.
As a result, display scaling causes image quality distortions, including blurring, moiré patterns, and flickering when scrolling. It also removes dithering, so gradients may appear less smooth.
An example of a moire pattern with two overlapping grids.
While these visual artifacts are undoubtedly present, the principle of unresolvable pixels still applies.
Rearranging the formula, angular resolution = 2dr tan (0.5 degrees) becomes d = angular resolution / 2r tan (0.5 degrees). Then we can calculate the viewing distance at which this occurs. For example, at the Retina angular resolution of 63ppd and pixel density of 163ppi for a 4K monitor, the result is around 22 inches.
This means that a person with average eyesight will not see the individual pixels on a 4K screen when viewed from this distance and further.
So you may not notice any distortion, depending on the viewing distance, your eyesight, and the quality of the display panel. (If your nose is pressed against the screen while you search for visual artifacts, you may be looking too closely.)
It’s not heavy, it’s my stamp
The other caveat of display scaling is performance. If your device renders the screen at a higher resolution than the display in a buffer and then scales it down, it must use additional compute resources. But, again, this may not have as big of an impact as you might think.
For example, Geekbench testing on a MacBook Air M2 showed a performance drop of less than 3% at scaled resolution, compared to native resolution, when using OpenCL, and less than 1% when using Metal . On the same machine, Blender’s performance dropped by around 1.1%.
Its importance depends on your use. If you need to squeeze every last CPU cycle out of your Mac, you better choose your monitor’s native resolution or upgrade to a Retina display. However, most users won’t even notice it.
The general takeaway from display scaling is that it’s designed to make your non-Retina monitor look better, not worse. For example, say you are doing detailed visual work where 1:1 pixel mapping is essential or long video exports where 1% time saving is critical. If so, chances are you already have a standalone Retina display or two. Alternatively, you can use display scaling on a non-Retina monitor without noticing a difference.

is to use a number that is different from your personal number, like
using a fake number from the Internet, and you can find many
applications in the Google Play Store that provide this service, and it
is a service that creates Americans, for example, or numbers that Brits
must activate social media accounts like WhatsApp, Facebook, Instagram
and other social media sites. With these apps you can create an account
on any app and get a fake number with which you can easily create an

Activating a Facebook account with a fake number has disadvantages and
harms, mainly losing your account in an application that provides a
service to create fake numbers. You are from Facebook on your phone
number, in this case you cannot receive the code because you do not have
a dummy account. Or because Facebook has received many complaints
