What Makes a Monitor a Retina Display?
Posted on October 2, 2022 by Larry
As I was writing my review of the ViewSonic VP2776 Color Pro monitor, I realized that there was a big difference in the quality of the display of monitors labeled “Retina display” compared to those that aren’t. But, what makes a monitor a “Retina display?”
What I learned is that Retina is a registered Apple trademark, “[a marketing term] for which there’s no concrete definition: put simply, a Retina display is any screen Apple has decided to call that. (MacWorld)
Retina display was introduced by Steve Jobs when he launched the iPhone 4. He described the screen as packed with so many pixels that you could no longer see individual pixels when viewing the screen at a distance of 12 inches (30 cm). In other words, he defined a retina display in terms of pixel density; which is measured in pixels per inch (ppi).
NOTE: While retina display monitors are generally thought of as 4K or larger, any monitor that can scale to 50% of its maximum resolution will look like a retina display. I proved this with the ViewSonic monitor which has a native resolution of 2560 x 1440. When scaled to 1280 x 720 (50%), text and image quality matched that of a retina display; though, obviously, the total resolution was much less.
Compare the fuzziness of the text in the Favorites bar – Retina (top) non-retina (bottom).
Both monitors are set to their default resolution. (Click to see a larger image.)
But, a hidden criteria in addition to pixel density is viewing distance. The closer your eyes are to the screen, the closer the pixels need to pack together. Digital billboards that you view from your car have a very low pixel density because they are viewed from a great distance. iPhones are just the opposite.
The specific pixel density varies by monitor. Some iPhones cram up to 458 pixels to the inch. MacBook Pro monitors (at least on my M1 MacBook Pro) display 144 pixels per inch. Traditionally, monitors display 72 ppi.
As an example, I have three monitors connected to my MacBook Pro (M1):
- Color LCD: The internal laptop monitor running in retina mode.
- LG HDR 4K: A 5K monitor running at 50% (“Retina”) resolution.
- ViewSonic VP2776: A 2.5K monitor running at full (non-retina) resolution.
NOTE: You can view a similar report for your system by choosing Apple menu > About this Mac, then click System Report and look at the Display section.
The big benefit to this increased pixel density is that text looks smoother, images look crisper, and edges no longer look stair-stepped.

FIRST, THE SCREEN
The easiest way to create a retina display is to take the native resolution of a monitor (say, 4K at 3840 x 2160 pixels) and cut it in half (1920 x 1080 pixels). This means that a block of four pixels now shares the work of one.
This is the real reason behind monitor manufacturers touting 4K, 5K, even 6K monitors.
Almost never does the the monitor display its full resolution. Instead, the macOS turns that monitor into a “Retina display” by cutting the resolution in half to improve image and text quality. Thus:
- 4K monitors (3840 x 2160) reduce the display to 1920 x 1080 pixels
- 5K monitors (5120 x 2880) reduce the display to 2560 x 1440 pixels
- 6K monitors (6016 x 3384) reduce the display to 3008 x 1692 pixels
NOTE: You can see this for yourself when you take a screen shot. Open the screenshot in Preview, choose File > Get Info and look at the File DPI setting. In the case of my Mac, it’s 144 dpi.
You can obviously set a monitor to its highest resolution, but text will look ragged and virtually all interface elements become desperately tiny. This brings us to the second key feature of a retina display.
THE INCREDIBLE SHRINKING ICONS
Icons on a retina display (top), non-retina at full resolution (bottom).
If all a retina display did was cut the resolution in half, icons would virtually disappear. So, Apple created HiDPI mode, which doubles the size of all interface elements while, at the same time, shrinking the size of the actual monitor display. This means that interface elements appear the same size on both retina and non-retina displays.
I’ve seen that for myself as I move elements between an LG 4K (retina) and a ViewSonic 2.5K (non-retina) monitor. While the smoothness of the text changes, the size of the interface elements do not.
Which, I must admit, is pretty cool. This required a lot of programming to make moving a window between monitors look like nothing happened.
NOTE: You can see this for yourself in the image at the top of this article.
AND YET, THERE’S MORE
Since “Retina Display” is an Apple marketing terms, Apple has extended the brand with the release of new iPhone and monitors:
- Retina HD
- Super Retina
- Super Retina HD
- Liquid Retina
- Liquid Retina HD
- Retina 4K
- Retina 5K
These are simply different ways to differentiate monitors with extra-dense pixels.
NOTE: I initially thought that “Liquid” might refer to refresh speeds, but I no longer think that’s the case.
Since this is an Apple marketing term, other manufacturers need to use other words to describe their own extra-dense monitors. But the concept is the same.
According to Macworld, since January, 2018, every Apple product with a built-in display supports Retina or better, with the exception of the MacBook Air and the 27″ Thunderbolt display.
SUMMARY
So, while the term “Retina Display” is reserved for Apple hardware, the results of increasing pixel density to improve text and images extend across all Mac-compatible monitors, whether from Apple or third-parties. The key to keep in mind is that, if you want your text to look it’s best, get at least a 4K monitor and expect the actual on-screen resolution to equal 1/2 the maximum monitor resolution.

The State of External Retina Displays, [Almost] 2022 Edition — Liss is More
In the middle of 2017 — roughly four and a half years ago — I went
on a search for a monitor to pair with my MacBook Pro while I was at work. I
wanted something that was “retina” quality — which means roughly
220 PPI.
While not terribly scientific, the rules of thumb I landed on were:
- No more than 24″ at 4K
- No more than 27″ at 5K
Back in 2017 — one thousand six hundred and sixty five days ago, as
I write this — I compiled a list of options. At the time there
were five. Two Dells, one run-of-the-mill LG, and the two LG UltraFine monitors.
The Lineup
1665 days later, let me revise my findings:
-
Budget Option: LG 24UD58-B 24″ 4K Monitor — ~$300
This is what I used, eventually two-up, at work. In 2017. The panel is
unremarkable, but for developers, it’s more than serviceable. Honestly,
I liked this setup.
Even two-up, it’s cheaper than the next
available option. -
Moderate Option: LG UltraFine 4K — ~$700
A fancier version of the above, which includes the option of daisy-chaining a
second 4K display. It also has a small USB-C hub internal to it, offering more
connectivity options. -
Deluxe Option: LG UltraFine 5K — ~$1300
The same thing as the LG UltraFine 4K, but without the option of daisy-chaining
a second display. It, too, has a small USB-C hub. I recently bought one
secondhand, and the rumblings are true: the stand is straight-up trash, and
the monitor itself is unreliable on the best of days. When it does work, though,
it’s great! -
Ridiculous Option: Apple Pro Display XDR — ~$5000 without a stand
Apple’s too-fancy-for-its-own-good option. It costs $5,000 without a stand.
To add their official stand is another $1,000. Oh, and if you
want the fancy nano-texture coating, that’s another $1,000.
So,
all-in, the Pro Display XDR is $7,000. Which is, charitably, absurd.
The above is the entire lineup. That’s it. Four options. Three of which existed
1665 days ago.
In [effectively] 2022, there are four
options for retina-quality monitors to attach to your Mac.
If there are others, please let me know, as I’d love to share them. I know
that others have existed at some time in the past — like the Dells I featured
in the first version of this post — but they’ve been discontinued and/or are
not readily available here in the States.
The Future
Last month I bought a 14″ MacBook Pro equipped with a M1 Max. This machine
is as fast as my iMac Pro, but considerably more portable. The battery life is by
no means infinite, but it’s enough to go work without power for several hours without
stressing. MagSafe is back — finally — and the keyboard is both reliable
and excellent. I have a HDMI port for when I travel, and an SD card reader.
The M1 Pro
and Max MacBook Pros are possibly the best machines Apple has released since I’ve
been observing the company, for about fifteen years.
Furthermore, the display on this machine is phenomenal. My buddy Jason Snell in
particular has been banging this drum for a while: on any other machine, the
displays alone would be the star of the show. They’re “true” pixel-doubled retina,
they have wide color gamut, they’re backlit by mini-LED, and they sport a fast
refresh rate of 120 Hz. They’re nearly perfect.
Why can’t we have this in an external monitor?
Granted, refreshing roughly 15 million pixels 120 times per second requires an
immense amount of data/bandwidth, so maybe that isn’t possible. However, everything
else about these panels should be possible in an external monitor. Even if we
have to suffer through a pedestrian 60 Hz. Why can’t we have an Apple-produced
5K screen that has mini-LED and wide color?
Why can’t we have an option between the unreliable $1300 LG 5K and the $5000+ XDR?
Over the last year or two, Apple has been doing a phenomenal job of filling the holes
in their product line.
For my money, the completely embarrasing monitor situation
is the lowest-hanging fruit. By a mile.
Take my money, Apple. Give me a monitor made for professionals that don’t do video
editing for a living. Please.

About the eye retina and the method of CFSF diagnostics
For millions of years, nature has been polishing and adapting the human eye for visual work. And it turned out not bad: a very sensitive «device» that functions well in different lighting conditions and is able to deal with objects of different sizes.
However, the advent of the personal computer forced us to reconsider our ideas about the capabilities of the human visual system. It turned out that when working with a monitor, our eyes get tired much faster, and sometimes they simply refuse to obey, ceasing to focus the image. Why?
The fact is that the working conditions behind the monitor are opposite to those that are familiar to our eyes. In ordinary life, we perceive mainly reflected light (unless we look at the sun, stars or artificial light sources), and the objects of observation are continuously in our field of vision for at least a few seconds. But when working behind a monitor, we are dealing with self-luminous objects and a discrete (flickering at a high frequency) image, which increases eye strain. If we add to this such frequently encountered factors as a sharp contrast between the background and characters, an unusual shape of characters, a different direction than when reading a book, the direction of view, glare and reflections on the screen, it becomes clear why almost every user is familiar with unpleasant sensations ( «sand» in the eyes, heat, pain, veil).
The technical level of modern monitors does not completely eliminate the impact of the factors listed above. However, this impact must be minimized by regulating a number of parameters, for which new sanitary standards have been issued — SanPiN (see the «Document» box). The main purpose of their implementation is to facilitate adaptation to factors unusual for the human body, thereby maintaining the performance and health of PC users.
Visual parameters
The main parameters of the image on the monitor screen are brightness, contrast, size and shape of characters, screen reflectivity, the presence or absence of flicker. In addition, SanPiN includes standards for several more parameters that characterize the shape and size of the working field of the screen, the geometric properties of signs, etc.
The brightness of the image (meaning the brightness of light elements, i.e., the sign for a negative image and the background for a positive one) is normalized in order to facilitate eye adaptation to self-luminous objects.
Fluctuations in brightness are also limited (within (25%)). The external illumination of the screen is normalized (100 — 250 lux). Studies have shown that at higher levels of illumination of the screen, the visual system gets tired faster and to a greater extent. question about what is best for vision: positive image (light screen and dark characters) or vice versa, negative image. There are pros and cons for both options. Hygienists believe, however, that if working with a PC involves working with paper (notebook, book) at the same time, then it is better to have dark characters on a light background on the monitor screen so that the eyes do not have to readjust all the time. When choosing a color scheme, preference should be given to the green-blue part of the spectrum. A survey conducted by us among students of the Moscow Medical Academy named after I.M. Sechenov, showed that 66% of users prefer a positive image for long-term work with the video terminal, mainly the «blue screen — black characters» option.
Quite often, the contrast between the background and characters on the screen also becomes a factor contributing to rapid eye fatigue. It is clear that low contrast makes it difficult to distinguish between characters, but too much contrast also harms. Therefore, the contrast should be between 3:1 and 1.5:1. At lower levels of contrast, workers experienced faster adverse changes in the ability to focus an image and the critical frequency of fusion of light flickers (see sidebar «On the retina and methods
KChSM diagnostics»), more complaints of eye fatigue and general fatigue were recorded.
The human eye cannot see small objects for a long time. That is why the size of characters on the screen is normalized. For example, the angular size of the sign should be between 16 and 60 arc minutes, which is between 0.46 and 1.75 cm if the user is looking at the screen from a distance of 50 cm (the minimum distance recommended by hygienists).
Hygienists noted that reading, especially in children, is significantly difficult and quickly leads to fatigue if the letters have unusual fanciful outlines.
For this reason, doctors are less than enthusiastic about the craze for a variety of fonts, especially in educational programs for children. Studies of vision in primary school children have shown that when reading a text typed in a more complex pattern, the reading speed drops faster in children, and a decrease in the critical frequency of light flicker fusion is more often noted. SanPiN includes several parameters that determine the acceptable shape and size of the sign. In particular, the ratio of the width of the sign to the height is normalized (0.5-1.0, better 0.7-0.9), i.e. the characters should be neither too narrow nor too wide.
Screen reflectivity must not exceed 1%. To reduce the amount of glare and facilitate concentration of attention, the monitor case should have a matte single-color surface (light gray, light beige tones) with a reflectance of 0.4-0.6, without shiny details and with a minimum number of controls and inscriptions on the front side .
The main specified visual characteristics of monitors and the corresponding allowable values for these characteristics are shown in Table 1.

Emissions and fields
Harmful factors that a person working with a monitor are exposed to X-rays, electromagnetic radiation, and electrostatic fields.
(Acceptable rates for these parameters are presented in table 2.)

Due to the current fairly stringent standards, X-ray doses from modern video monitors are not harmful to most users.
The exception is people with hypersensitivity to it (in particular, X-ray radiation from the monitor is dangerous for pregnant women, as it can have an adverse effect on the fetus in the early stages of development).
Experts have not come to an unequivocal conclusion regarding the impact of electromagnetic radiation on the human body, but it is clear that the levels of radiation recorded near the monitor (table 2) do not pose a danger.
The monitor also generates an electrostatic field. The levels of its intensity are small and do not have a significant impact on the human body, in contrast to the higher levels of the electrostatic field that are typical for industrial conditions. More significant for users is the ability of charged microparticles to adsorb dust particles, thereby preventing them from settling. Breathing in such a dusty «cocktail» means exposing yourself to an additional risk of allergic diseases of the skin, eyes, and upper respiratory tract.
In general, a modern person is surrounded by such a number of harmful factors, even if of low intensity, that his body, sufficiently resistant to the influence of each of them separately, may not withstand their general onslaught.
That is why doctors tighten the requirements for the maximum permissible levels of such factors and emphasize the importance of studying the problem of the complex impact of factors of low intensity.

«Hygienic requirements for video display terminals, personal electronic computers and organization of work: Sanitary rules and norms» (SanPiN 2.2.2.542-96. M .: Information and Publishing Center of the State Committee for Sanitary and Epidemiological Supervision of Russia, 1996. 64 p.
) approved by the resolution of the State Committee for Sanitary and Epidemiological Supervision of Russia dated July 14, 191996. They replaced the previously existing «Temporary Sanitary Norms and Rules for Employees of Computing Centers» (approved by the USSR Ministry of Health on March 2, 1988), «Temporary Sanitary and Hygienic Norms and Rules for the Design, Equipment, Maintenance and Mode of Operation on Personal Electronic Computers and video display terminals in computer rooms and display classes of all types of secondary educational institutions» (approved by the USSR Ministry of Health on 10/20/89) and «Methodological guidelines for the prevention of overwork of university students when working with video terminals» (approved by the USSR Ministry of Health on 03/05/88).
Simultaneously with SanPiN, mandatory hygienic certification of monitors and personal computers is introduced, i.e., according to the new sanitary rules, «it is forbidden to approve regulatory and technical documentation for new video display terminals and personal computers, put them into production, sell and use them in production conditions, the educational process and at home, as well as their purchase and import into the territory of the Russian Federation without the coordination of regulatory and technical documentation with the bodies of the State Sanitary and Epidemiological Supervision of Russia and the receipt of hygiene certificates.
All types of domestic and foreign monitors previously developed and in operation must be tested within a year after the approval of these rules.
Seven research institutions took part in the creation of the document, including the Research Institute of Occupational Medicine of the Russian Academy of Medical Sciences, the Research Institute of Hygiene named after F.F. Erisman, Research Institute of Human Ecology and Environmental Hygiene of the Russian Academy of Medical Sciences, Research Institute of Hygiene and Prevention of Diseases in Children, Adolescents and Youth.
Behind each line of the regulations are long-term experiments on animals and observations of the health and performance of PC users.
Since the main load during work at the monitor falls on the eyes and the central nervous system, when developing standards for adults and children working on a computer, we studied visual and mental performance, the state of the oculomotor muscles, the accommodative apparatus and the retina of the eye.
Evidence-based methods were used that objectively reflected fatigue and pre-pathological conditions, complaints, morbidity, data from regular medical examinations were collected and analyzed.

About the eye retina and CFSM diagnostics
Visual perception is a complex multi-stage process that begins with the formation of an image on the retina and ends with the appearance of a visual image in the cerebral cortex.
When we look at the surrounding objects, we get the impression that our visual sensations exactly match the light stimuli. It seems to us that in every direction in space we see light emanating from there at the moment. You might think that the operation of our visual system resembles the transmission of a television image. However, it is not. Studies show that if the image of an object remains motionless relative to the retina and does not change in color and brightness, then after 1-3 seconds a person ceases to see the differences between parts of the object.
At the same time, the person ceases to see the color of the object. For this reason, for example, if you tensely concentrate on a small detail of an image or on a distant object, then the corresponding object does not become clear, but, on the contrary, gradually blurs, losing clarity and color.
However, it is enough to sharply change the illumination of an object in order to restore its perception in detail. Experiments have shown that when an image is perceived, continuous eye movements occur, as a result of which the intensity of the light effect on the retina constantly changes.
Activities that require the retina to perform work that is inconvenient for it, leads to an excessive load on the visual system. Such activity, in particular, is working on a computer. Moreover, in addition to the need to look at small objects, communication with the monitor delivers another inconvenience to the visual system: the operator’s attention is almost constantly directed to the center of the screen, and the main load falls on the central zone of the retina.
Fatigue contributes to a large extent and the fact that the work of the muscles of the eyeball is reduced, and consequently, blood circulation in the retina.
To diagnose pathological processes in the visual system, as well as to determine the degree of eye fatigue, the method of studying the critical frequency of light flicker fusion — CFSM diagnostics is often used.
The method is based on the fact that the retina perceives a pulsating light signal differently: if the pulsation frequency is low, we see a series of flashes — flashes, and at a high frequency, the signal is perceived as an even glow. Thus, by increasing the frequency of pulsations, it is possible to set its boundary value, beyond which the eye ceases to distinguish flickering. This is the CCSM.
In healthy people and people with different types of eye pathology, the indicators of CFFF are different. For example, studies conducted at the All-Russian Research Institute of Eye Diseases. Helmholtz, showed that the average value of CFFF in healthy children aged 5 to 15 years is 45-55 Hz.
In the case of ocular pathology, CFFF is lower (26-37 Hz), its value depends on the nature of the pathology of the visual analyzer.
In a healthy adult, the CFFF is 45-50 Hz for the central part of the retina. On the periphery, the CFSM is always 10-15 Hz higher. Therefore, for example, with «peripheral vision» we see how the screen of a computer or TV flickers.
Fatigue of the visual system usually leads to a drop in CFFF by a few hertz. Thus, for PC operators, the CFFF can decrease by 5-6 Hz compared to the initial value, and only in the central part of the retina, which bears the main load.
Studies conducted in a group of students and schoolchildren have shown that the magnitude of the decrease in CFFF when working on a computer is an individual characteristic. For some subjects, the CFSM indicator decreased by 2-3 Hz after an hour of work, for others — after 3-4 hours of work.
The advice is very simple. If the CFFF has decreased by 2-3 Hz compared to the initial level, you need to take a break.
If a young person has a CFFF value below 40 Hz, an ophthalmologist should be consulted.

How to choose the best monitor for your eyes
We understand what parameters can affect the health of the user and what you should pay attention to when buying a monitor for comfortable work and safe play
If you care about your health, then when choosing a monitor, be sure to consider its safety for vision. A properly selected monitor can make long-term work at the computer comfortable, and games and watching movies are not tiring.
But first, let’s figure out what to avoid.
What exactly affects vision
If you notice that after a short stay at the computer, your eyes are baked and watery, or there may be cramps in the temples, your monitor may be dangerous to health, or inappropriate settings are set:
Screen flickering
This indicator, which is determined by the type of matrix, display backlight system and frequency.
The lower the flicker frequency, the faster the user gets tired both during work and in games. You can check the frequency by swiping an object in front of the monitor. If you see an even smeared trace, the flicker intensity frequency is satisfactory, if the object is perceived as several separate ones, the frequency is insufficient and you should not spend a lot of time behind such a monitor.
High brightness
Brightness imbalance is one of the most dangerous factors. An incorrect setting of this parameter can have a detrimental effect on vision, especially if the brightness is set to high when working in the dark for a long time.
Weak or excessive contrast
Incorrectly adjusted monitor contrast forces the user to carefully peer into the image. At this time, the eye muscles are in constant tension, trying to focus on blurry contours. Viewing such a monitor for a short period of time can lead to headaches. Long work is guaranteed to result in vision problems.
Blue Balance
The colors of the blue spectrum are irritating to the eyes, and in a dark room at high brightness they slowly burn out the retina.
User comfort
Separate attention deserves the distance to the monitor and the working posture. The screen should be at right angles to the direction of view. And the distance to it should be at least an outstretched arm with an open palm.
Selection tips
We have already written more than once how to choose the best monitor for games, and today we will talk about the selection of parameters that are responsible for the comfort and health of the user.
Optimum diagonal
To date, the most common are monitors with a diagonal of 23.8» — 24». They are also the best for the job. Such a diagonal allows you to place a couple of program windows or documents and comfortably track all actions. Smaller size is not recommended, and when buying a larger screen size, try to increase the working distance.
Dot density
Dot density or ppi is a parameter that is determined by the diagonal size and resolution. In turn, the density of points determines such characteristics as contrast and image clarity.
The higher the dot density, the less strain the user’s vision experiences. Ppi is not always indicated in the specifications for the monitor, but having the diagonal size and resolution available, you can calculate it yourself. A comfortable resolution should be at least 110 — 120. It is this number of points that the eye can distinguish at a working distance.
Matrix type
The choice of the type of matrix should be determined by the purpose of buying a monitor.
Matrix TN — the choice of gamers. Monitors with TN panels perfectly support the dynamics of the game, maintaining the clarity of the image without blurring the edges. The disadvantages include a small vertical viewing angle and a shift in the color scheme when the monitor is not installed correctly.
The VA panel is the best choice for video and photo applications as VA panel monitors are the only ones that display natural deep blacks. The disadvantage is the low response time.
The IPS matrix demonstrates the most accurate color reproduction. Previously, these monitors were considered not fast enough, but the latest models have brought monitors with IPS matrices, but the leading positions in demand for games and work.
State of the art vision protection technology
Many manufacturers equip monitors with technologies to make long stays at the computer comfortable. Here are the most common
Flicker Free refers to monitors with flicker-free or flicker-free backlights of 1000 Hz or higher. We are talking about the backlight, and not about the refresh rate.
The filter or blue spectrum suppression function is an additional option that can be manually activated in the monitor settings. Please note that activating this function may significantly distort the color reproduction.
A matte screen can also significantly reduce eye strain, as the image on matte monitors is softer and free of glare.
Intelligent Light Detection is a technology developed for laptops to save battery power. However, very soon she found popularity among desktop monitors, setting the screen parameters in accordance with the situation in the room.
Preset modes are technologies that even the most budget monitors are equipped with. You can select one of the available image adjustment schemes or change the mode according to your working conditions.
Curved screen is fashionable, stylish and presentable. But in fact, such a design is designed to provide the correct viewing angle at any point of the monitor, which significantly reduces eye strain.
Top 9 Vision Monitors0033
The Philips 245E1S is a budget 23.8″ IPS monitor that’s the perfect choice for eye-straining office work.
The LG 27GL850 is a 27″ mid-range gaming monitor with an IPS matrix, has positive reviews, and is noted by the owners as comfortable in dynamic games.
