Retina Display is a brand name used by Apple for its series of IPS LCD and OLED displays that have a higher pixel density than traditional Apple displays.trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.

The Retina display has since expanded to most Apple product lines, such as Apple Watch, iPhone, iPod Touch, iPad, iPad Mini, iPad Air, iPad Pro, MacBook, MacBook Air, MacBook Pro, iMac, and Pro Display XDR, some of which have never had a comparable non-Retina display.marketing terms to differentiate between its LCD and OLED displays having various resolutions, contrast levels, color reproduction, or refresh rates. It is known as Liquid Retina display for the iPhone XR, iPad Air 4th Generation, iPad Mini 6th Generation, iPad Pro 3rd Generation and later versions,Retina 4.5K display for the iMac.

Apple"s Retina displays are not an absolute standard for display sharpness, but vary depending on the size of the display on the device, and at what distance the user would typically be viewing the screen. Where on smaller devices with smaller displays users would view the screen at a closer distance to their eyes, the displays have more PPI (Pixels Per Inch), while on larger devices with larger displays where the user views the screen further away, the screen uses a lower PPI value. Later device versions have had additional improvements, whether an increase in the screen size (the iPhone 12 Pro Max), contrast ratio (the 12.9” iPad Pro 5th Generation, and iMac with Retina 4.5K display), and/or, more recently, PPI count (OLED iPhones); as a result, Apple uses the names “Retina HD display", "Retina 4K/5K display", “Retina 4.5K display", "Super Retina HD display", “Super Retina XDR display”, and "Liquid Retina display" for each successive version.

When introducing the iPhone 4, Steve Jobs said the number of pixels needed for a Retina display is about 300 PPI for a device held 10 to 12 inches from the eye.skinny triangle with a height equal to the viewing distance and a top angle of one degree will have a base on the device"s screen that covers 57 pixels. Any display"s viewing quality (from phone displays to huge projectors) can be described with this size-independent universal parameter. Note that the PPD parameter is not an intrinsic parameter of the display itself, unlike absolute pixel resolution (e.g. 1920×1080 pixels) or relative pixel density (e.g. 401 PPI), but is dependent on the distance between the display and the eye of the person (or lens of the device) viewing the display; moving the eye closer to the display reduces the PPD, and moving away from it increases the PPD in proportion to the distance.

The displays are manufactured worldwide by different suppliers. Currently, the iPad"s display comes from Samsung,LG DisplayJapan Display Inc.twisted nematic (TN) liquid-crystal displays (LCDs) to in-plane switching (IPS) LCDs starting with the iPhone 4 models in June 2010.

Reviews of Apple devices with Retina displays have generally been positive on technical grounds, with comments describing it as a considerable improvement on earlier screens and praising Apple for driving third-party application support for high-resolution displays more effectively than on Windows.T220 and T221 had been sold in the past, they had seen little take-up due to their cost of around $8400.

The sort of rich, data-dense information design espoused by Edward Tufte can now not only be made on the computer screen but also enjoyed on one. Regarding font choices, you not only need not choose a font optimized for rendering on screen, but should not. Fonts optimized for screen rendering look cheap on the retina MacBook Pro—sometimes downright cheesy—in the same way they do when printed in a glossy magazine.

If you"ve ever had a flickering MacBook Pro® screen, you know how easily it can ruin your work day or movie night. Fortunately, there are some simple fixes that can help resolve the problem.

At Asurion, when tech breaks, we fix it—whether your MacBook® won"t turn on or it needs a factory reset. We"ll walk you through what to do if your MacBook Pro screen is flickering so you can get back to what"s important.

Updating your MacBook Pro to the latest iOS®version can solve all kinds of issues, including a flickering screen. Here"s how to confirm that your laptop is running the latest version of macOS®.Open System Preferences.

Another cause of screen flickering lines on your MacBook Pro? Recently downloaded applications and files, which may have viruses. To erase them from your computer:Go to the dock and click on the Finder.

Many MacBooks come with two graphics systems. They also come with the automatic graphics switching option turned on to enable your computer to use the best one for whatever you"re doing—and to maximize battery life. But sometimes the two graphics systems can cause screen flickering. To turn off the setting:Go to Apple menu>System Preferences>Battery.

You"ll see a list of options. Clear the automatic graphics switching checkbox. In macOS Catalina 10.15 and earlier, this setting is in Energy Saver preferences.

Your MacBook Pro"s System Management Controller (SMC) determines how your computer manages power. Much like restarting and updating, resetting the SMC can resolve various glitches, including a flickering screen. There are different ways to reset the SMC, depending on which model you have.

If you"ve tried the troubleshooting tips above but the screen flickering continues on your MacBook Pro, it"s time to run Apple Diagnostics. It will help figure out if there"s a hardware issue.Shut down your computer.

In both cases, Apple Diagnostics will run a scan for any problems and identify where a defect may be. You"ll receive one or more reference codes, which you can read more about here. From here you can do a few things:Repeat the test by clicking “Run the test again" or pressing Command + R.

After looking at the performance of Apple"s M1 Pro SoC powering the new MacBook Pro 16, and beyond reviewing the laptop itself, there"s another interesting component in this laptop that"s worth looking into, and that"s the mini-LED 120Hz display. So today we"re going to take a closer look at what Apple is doing with their brand new screen.

As you"re fully aware, we have a lot of experience testing and reviewing displays, however we mostly cover gaming monitors not laptop displays, so this is going to be a little different. We"re going to run through some tests and provide our thoughts on how good this display is as someone that looks at lots and lots of displays each year.

There are two versions of the new MacBook Pro and we"ve got the 16-inch version, although the 14-inch model"s display is very similar just smaller and with a different resolution. Apple calls this particular display a "Liquid Retina XDR display" which is typical Apple marketing speak. If I translate this into what Apple actually means, they are giving you a high resolution full array local dimming mini-LED LCD with true HDR functionality.

If we dive deeper into the specs, the 16.2-inch panel has a resolution of 3456 x 2234 which continues Apple"s tradition of using non-standard resolutions across their line-up. Apple doesn"t disclose the exact technology used here, but it"s an LCD panel which appears to be IPS-like in design. The backlight has 10,000 mini-LEDs for impressive zone density at this size, allowing for a contrast ratio of 1,000,000:1 and peak brightness up to 1,600 nits in the HDR mode on paper.

As for refresh rate, Apple are offering up to 120Hz with adaptive sync, which they"ve rebranded into "ProMotion" although this sort of functionality has been available for many years now in other laptops and displays. The combination of everything though is a first, and the only rivals to this sort of panel are the latest wave of 4K OLED panels seen in a few high-end Windows laptops.

The MacBook Pro"s display is a wide gamut display with 99% coverage of the DCI-P3 color space. That"s an excellent result for any creator looking to produce content in that gamut. This also means perfect sRGB coverage, so if you"re designing web content, creating SDR videos, or working with wide gamut HDR videos then Apple is providing you the tools to do that.

Unfortunately the performance outside these gamuts is not great, specifically what"s missing is Adobe RGB coverage which is relevant for photography work. Due to covering P3 fully we do get over 90% Adobe RGB coverage, but it"s missing the top range of greens that differentiate Adobe RGB from other color spaces, so this laptop isn"t suitable for that sort of work. Apple also knows this, because they don"t provide an Adobe RGB color profile, while you do get various P3 and Rec. 709 profiles.

Where the MacBook Pro"s display ends up in terms of color gamut is typical for a modern "creator" laptop, the majority of top-end laptop displays have really good coverage of sRGB and P3. Where it falls a little short is in that Adobe RGB coverage, and a competing display like the Samsung OLED you get in devices such as the Gigabyte Aero 15 OLED does offer a wider color gamut with full Adobe RGB coverage. That"s not to say the MacBook Pro"s gamut is bad or anything, it"s just not as wide or as versatile as I"ve seen.

Where the display is extremely impressive is in its color calibration, and this is helped significantly by macOS doing a much better job of color management than Windows. The various color profiles included by default work across far more apps in macOS than they would on Windows and this is one area where Windows needs a bit of an overhaul.

If we look at the options provided in the MacBook Pro"s display settings, you"ll find quite a few options including Apple Display and Apple XDR Display presets, along with a decent array of creator focused modes for gamuts like BT.709, sRGB and P3. Apple also offers True Tone and Night Shift functionality, which some people might find useful but ultimately hurt color accuracy. I"ve disabled True Tone for testing.

When looking at the default Apple Display profile, performance is pretty good by default. When displaying sRGB content in this mode, it"s quite likely color management will activate in the app you"re using to display the content correctly and accurately, instead of oversaturating it up to the full P3 gamut of the screen. When looking at saturation sweeps as an example, we find excellent deltaE performance, and good results in ColorChecker as well, especially around skin tones which are crucial to get right.

Based on this you should probably just leave your MacBook in the Apple Display mode for everyday use as it"s accurate enough for sRGB content and will also let you benefit from wide gamuts where needed. The performance in the Apple Display XDR mode is similar as well for SDR content, so that"s an option if you want to also use HDR at times.

If you want even better color accuracy, Apple"s included profiles might be for you. For example, the built-in sRGB mode is even better at displaying sRGB content, with accuracy equivalent to performing a full calibration yourself.

I suspect the reason why this mode is better than the default mode is that it"s specifically tailored to showing sRGB content, rather than the more general default mode that is designed for use in multiple scenarios. Color management is hard and creating specific modes for each gamut is generally the best approach, so it"s great Apple has done this for you.

There is a downside to these modes, and that"s locked brightness. Now technically each of these color specifications do stipulate a brightness level for mastering: sRGB is 80 nits, DCI-P3 is 48 nits and Rec. 709 is 100 nits - and the MacBook Pro gets this right.

However that limits the usefulness of these modes for viewing content, where the mastering brightness level is less relevant and your ambient conditions are more important. I"d like to see a brightness override toggle, so that each of these modes is still useful for mastering, but can also deliver the best accuracy for watching other content. That would improve the versatility of the display and give you the ability to fine tune accuracy beyond the already very good default mode.

In the regular Apple Display mode for viewing SDR content, I measured peak brightness at around 520 nits, with a variable black level. Bizarrely, the MacBook Pro appears to change its black level limit in the SDR mode depending on the ambient light conditions, even with True Tone disabled. In a lit room, the black level was capped to 0.02 nits, delivering around a 26,000:1 contrast ratio.

In any case, the mini-LED backlight is active at all times, even in SDR content, to improve the contrast ratio in SDR scenes. There are so many zones here that it"s unlikely you"ll spot much blooming in practice, I found it negligible for SDR use even in tricky desktop apps with harsh edges between light and dark areas. The dimming algorithm is tweaked nicely to avoid this situation and there are simply more than enough zones to prevent lingering issues. This sort of attention to detail is what I"d love to see more in the standalone monitor space, along with higher zone counts, of course.

In the HDR mode, brightness is extremely impressive. There"s no major difference between sustained and peak brightness, so there"s no automatic brightness limiter that activates after a short period to dim the screen in intensely bright scenes. Brightness is as high as 1670 nits at small window sizes, and over 1500 nits at 50%, before dropping to around 1150 nits for a full screen sustained white window. That"s impressive, although it does come with a corresponding increase to power consumption, so running the display at over 1000 nits all the time isn"t advisable on battery.

This performance also destroys basically any other LCD based monitor I"ve looked at before. On the standalone monitor side, it"s virtually unheard of right now to see LCD zone counts higher than a couple of thousand. This limits worse case contrast to around 12,000:1 in the case of the 2,000-zone Samsung Odyssey Neo G9 with VA technology, or just 4,000:1 in a checkerboard test.

Apple choosing to use 5-10x the zone count massively improves the achievable contrast ratio in tricky situations and I"d say this amount of zones - and the density of zones - is what is required as a minimum for the best HDR experience with an LCD panel. Even Apple"s own ridiculously overpriced Pro Display XDR doesn"t compare as it has a paltry 576-zone backlight and it was criticized at launch for poor blooming compared to professional level HDR mastering displays. The MacBook Pro"s display will be far better for producing HDR content, aside from the small size.

So from one perspective it"s easily one of the best LCD-based HDR experiences I"ve seen, but on the other hand it isn"t a self-lit panel like an OLED which is completely free of blooming and in some situations OLED still delivers better HDR. Of course, OLEDs have other drawbacks such as lower brightness levels and the risk of burn in so I can understand why Apple would opt for LCD instead. Besides this one complaint though the HDR experience is excellent, especially for a laptop.

Unfortunately there is a major drawback to the Liquid Retina XDR display used on the new MacBook Pros, and that"s the motion performance. While it"s nice to see Apple upgrade the refresh rate to 120Hz compared to the 60Hz they were using previously, the display being used here doesn"t have the appropriate level of response times to keep up with that 120Hz refresh rate. The panel is actually very, very slow, which is a disappointment.

I was hoping to provide a full breakdown of motion performance using the standard graphs we use for monitor reviews... until I realized that my response testing tool doesn"t work on macOS and even creating one graph manually to a decent level of accuracy with all the transitions would have taken an entire day.

In a full black to full white transition, gamma corrected as per our current test methodology, the MacBook Pro"s display is exceptionally slow, taking nearly 100ms to complete this rise. Even if we apply exceptionally generous tolerances and only measure 60% of the total transition time, it still takes 39ms to transition, which is one of the worst results I"ve ever measured.

This is exacerbated by using a combination of IPS-like LCD technology, and an always-active mini-LED backlight, noting that both the LCD layer and mini-LED need to change to transition fully.

Luckily full transition fall times aren"t as horrific, though still reasonably poor at over 15ms even with our very generous 20% tolerance. The real transition time is more like 35ms, so less than half that of the rise time, but far slower than most other LCDs out there. The best laptop grade OLED panels can perform these transitions in under 2ms with the same test conditions, making them an order of magnitude faster.

I tested a few more transitions of varying degrees and typically the MacBook Pro would fall between 20 and 40ms, though luckily there is no overshoot to speak of. When viewing UFO test results, you can see the product of these horrific response times: a substantial blur trail behind moving objects. Even though the panel can feel somewhat smooth to use because it has a moderate refresh rate of 120Hz, the actual clarity in motion is terrible and this impacts the usefulness of the higher refresh rate.

Right next the MacBook Pro we have the Aero 15 OLED"s panel which has half the refresh rate at just 60Hz, but massively faster response times. You"ll see here that even though the MacBook Pro"s display is twice as fast in refresh rate, the extremely slow response behavior limits motion clarity to more like a 60Hz monitor or worse. The level of smearing is insane and I"m not sure how a modern LCD could end up this slow, Apple really should have experimented with some sort of overdrive.

Now, all Apple fans are probably sitting here annoyed that I"m criticizing the display for motion performance because the MacBook Pro isn"t a gaming laptop. And they"re right, it"s not a gaming laptop. But motion performance is relevant beyond gaming, it impacts things as basic as scrolling through websites or even watching videos. Fast moving video content like sports is affected due to slow transition times, and scrolling through text can show really bad ghosting trails, especially with white text on a black background. But really anything on this display that moves, especially stuff that moves fast, can quickly become a blur fest.

There is no doubt that the MacBook Pro"s Liquid Retina XDR display is excellent for content creation. It has perfect P3 color gamut coverage and outstanding factory calibration, with particular attention to detail paid to multiple color specifications for mastering.

Apple provides many different profiles that are all above average to great in terms of accuracy, and this should provide peace of mind that if they are using this display in one of those color spaces, everything is looking correct as it should. macOS also helps here, thanks to superior color management than Windows.

The Liquid Retina XDR display has impressive HDR specifications and performance. A mini-LED backlight zone count of 10,000 is the star of the show in this respect, significantly reducing blooming compared to other LCD-based HDR monitors, and providing exceptionally high brightness. The level of performance is good enough for both enthusiast level mastering and HDR playback, so the MacBook Pro is a great device for video editing on the go when you also factor in its overall performance.

A few nitpicks aside, the major downside to the display is motion performance. This display is exceptionally slow even for an LCD, despite packing a 120Hz refresh rate. This affects areas including web browsing and any work with text as you scroll through content, and blur trails can be visible across a wide range of use cases, not just gaming. It"s not bad enough to negate the benefits you get elsewhere, but Apple needs to put a lot of work into optimizing how quickly their panels transition. I also feel the lack of HDMI 2.1 on the MacBook Pro is a bit puzzling, going HDMI 2.0 for external monitors (in addition to Thunderbolt) is a bit annoying.

Now comes the ultimate question: is this the best laptop display ever, as Apple claims it is? That will depend on your perspective. Evidently, if you"re buying a high-performance laptop for gaming then no, but the MacBook Pro is clearly not suited nor aimed at gamers. But if we put that aside and ask about the best display for content creation and productivity, we think Apple has a solid claim to that throne.

The only real competition right now are OLED panels, which come with their own set of strengths and weaknesses. There are a few other mini-LED laptop options on the Windows side, like the screen you get in the Acer Predator Helios 500, but that display only has 512 zones, not the 10,000 on offer here. So it"s a battle between the MacBook and the OLEDs you see in products like the Gigabyte Aero 15 OLED.

The reasons to get an OLED display over this LCD would be in terms of its self-lit pure HDR experience with zero blooming, significantly faster response times for better motion clarity, and wider color gamut allowing for accurate work in the Adobe RGB color space as well as P3 and Rec.709. However, the drawbacks are also significant, including a 60Hz refresh rate limitation with current 4K offerings, the risk of permanent burn in, and significantly lower brightness. Actual implementations we"ve seen also lack the calibration Apple is offering.

On the balance of things, I"d prefer to get the Liquid Retina XDR in the new MacBook Pro than an OLED, especially for color-accurate content creation, and the HDR experience is close enough to OLED that I can forgive very minor blooming on occasion. I wouldn"t say Apple is miles in front with this screen, but it"s certainly very impressive and calling it the best display for production work is justified.

When personal computers were first invented, the screen resolutions they came with was the resolution you got. Now most computers present you with display options, enabling the screen of your computer to simulate other formats. MacBooks are no exception. A problem can arise when you"ve changed your screen settings and can"t remember the default settings. But it"s really not that much of a problem, as one simple step will restore the default settings.

Simulating Other Computer Screens If you"re producing material that people may be using or viewing on a smaller resolution screen than your MacBook"s, it"s a good idea to select a screen resolution that will match other people"s computers. You can try several different resolutions to see the influence of display size on image quality. You can then tailor your design to meet the needs of different displays.

Dual-Screen Operation The MacBook enables you to add a second display. That is, you can plug a cable into the video output socket on the MacBook, and then use an external display to mirror your MacBook"s display or to extend the desktop over to the external display. Your choice of mirroring or extending and the specifics of the external display will drive your choice for screen size.

Native Display When computer folks talk about native resolution, they"re talking about the maximum capabilities built into the screen of the computer. That is, the native resolution corresponds to the actual number of physical pixels on the screen. The native resolution for the original MacBook series is 1,280 by 800 pixels; the MacBook Pro 13.3-inch has the same screen format, while the 15.4-inch model has a 1,440-by-900 pixel format. The MacBook 13.3-inch with retina display has a pixel format of 2,560-by-1600 pixels. You can find the display format for your screen by selecting the "Displays" option from the System Preferences utility. The largest number of pixels in the list corresponds to your screen"s native format.

Returning to the Default Display Setting If you"ve changed the resolution of your MacBook display, you can go back to the default easily. Open the "System Preferences" utility and select "Displays." If you"ve been using an external monitor, now would be a good time to unplug it, just to minimize confusion. A list of resolutions presents itself. Scroll down to the largest format in the list. That"s the native resolution of your display -- and the default setting for your computer. Select that option and you"re back to the default settings.
