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 debuted in 2010 with the iPhone 4 and the iPod Touch (4th Generation), and later the iPad (3rd generation) where each screen pixel of the iPhone 3GS, iPod touch (3rd generation), iPad 2 was replaced by four smaller pixels, and the user interface scaled up to fill in the extra pixels. Apple calls this mode HiDPI mode. In simpler words, it is one logical pixel = four physical pixels. The scale factor is tripled for devices with even higher pixel densities, such as the iPhone 6 Plus and iPhone X.

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.

In practice, thus far Apple has converted a device"s display to Retina by doubling the number of pixels in each direction, quadrupling the total resolution. This increase creates a sharper interface at the same physical dimensions. The sole exception to this has been the iPhone 6 Plus, 6S Plus, 7 Plus, and 8 Plus, which renders its display at triple the number of pixels in each direction, before down-sampling to a 1080p resolution.

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.

Apple markets the following devices as having a Retina display, Retina HD display, Liquid Retina display, Liquid Retina XDR display, Super Retina HD display, Super Retina XDR display or Retina 4K/5K/6K display:

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.

Raymond Soneira, president of DisplayMate Technologies, has challenged Apple"s claim. He says that the physiology of the human retina is such that there must be at least 477 pixels per inch in a pixelated display for the pixels to become imperceptible to the human eye at a distance of 12 inches (305 mm).Phil Plait notes, however, that, "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4S"s pixels are resolved. The picture will look pixelated. If you have average eyesight [20/20 vision], the picture will look just fine... So in my opinion, what Jobs said was fine. Soneira, while technically correct, was being picky."

The first smartphone following the iPhone 4 to ship with a display of a comparable pixel density was the Nokia E6, running Symbian Anna, with a resolution of 640 × 480 at a screen size of 62.5mm. This was an isolated case for the platform however, as all other Symbian-based devices had larger displays with lower resolutions. Some older Symbian smartphones, including the Nokia N80 and N90, featured a 2.1 inch display at 259 ppi, which was one of the sharpest at the time. The first Android smartphones with the same display - Meizu M9 was launched a few months later in beginning of 2011. In October of the same year Galaxy Nexus was announced, which had a display with a better resolution. By 2013 the 300+ ppimark was found on midrange phones such as the Moto G.Samsung Galaxy S4 and HTC One (M8) had 1080p (FHD) screens around 5-inches for a 400+ PPI which surpassed the Retina density on the iPhone 5. The second major redesign of the iPhone, the iPhone 6, has a 1334 × 750 resolution on a 4.7-inch screen, while rivals such as the Samsung Galaxy S6 have a QHD display of 2560 × 1440 resolution, close to four times the number of pixels found in the iPhone 6, giving the S6 a 577 PPI that is almost twice that of the iPhone 6"s 326 PPI.

Apple has determined that, in a limited number of older generation 15-inch MacBook Pro units, the battery may overheat and pose a fire safety risk. Affected units were sold primarily between September 2015 and February 2017 and product eligibility is determined by the product serial number.

First check to see which 15-inch MacBook Pro you have. Choose About This Mac from the Apple menu () in the upper-left corner of your screen. Confirm your model is "MacBook Pro (Retina, 15-inch, Mid 2015)." If you have that model, enter your computer"s serial number below to see if it is eligible for this program.

This program is for battery replacement only. Please contact Apple Support and speak with an Advisor if you would like to arrange paid service for any additional issue.

What are all the differences between the 15-Inch "Mid-2015" Retina Display MacBook Pro models? What are the differences between these models and the "Mid-2014" models replaced?

Please note that 15-Inch "Mid-2015" Retina Display MacBook Pro models with dual graphics have been discontinued. Apple continues to sell 15-Inch "Mid-2015" Retina Display models with integrated graphics as new. This Q&A has been updated with the latest details.

There are two stock 15-Inch "Mid-2015" Retina Display MacBook Pro models -- the still current MacBook Pro "Core i7" 2.2 15" (IG) and the discontinued "Core i7" 2.5 15" (DG) and -- as well as three BTO/CTO options -- the still current MacBook "Core i7" 2.5 15" (IG) and "Core i7" 2.8 15" (IG) as well as the discontinued "Core i7" 2.8 15" (DG) -- which EveryMac.com documents as their own models for reader convenience. The equivalent 13-Inch systems technically are "Early 2015" models and EveryMac.com compares the 13-Inch "Early 2015" models to the 15-Inch "Mid-2015" models separately as a result.

The two standard 15-Inch "Mid-2015" MacBook Pro models are most notably differentiated by graphics systems, which is why EveryMac.com documents these as the "IG" and "DG" models, for Integrated Graphics and Dual Graphics, respectively. However, these notebooks also differ by processor and standard storage. They have different identifiers and price points, as well:

The "Mid-2015" MacBook Pro models are quite similar to the "Mid-2014" MacBook Pro models replaced -- the MacBook Pro "Core i7" 2.2 15" (IG), "Core i7" 2.5 15" (IG), "Core i7" 2.8 15" (IG), "Core i7" 2.5 15" (DG), and "Core i7" 2.8 15" (DG). Both lines even share the same "Haswell" processors.

The most notable differences between the "Mid-2015" models and their predecessors are that the "Mid-2015" MacBook Pro models have a more advanced trackpad, faster flash storage, and a higher capacity battery. The higher-end "Mid-2015" models have modestly faster graphics than the predecessors, as well. However, because the models are so similar, identifiers are particularly important for differentiation and the similarities are well worth evaluating in-depth, too.

Additionally, each of these notebooks has a full-size "chiclet-style" backlit keyboard, integrated stereo speakers, dual microphones, and an integrated 720p FaceTime HD webcam. The "Mid-2014" models (as well as earlier ones) have a "no button" trackpad with "inertial scrolling" support, whereas the "Mid-2015" models have a more advanced "Force Touch" trackpad.

In marketing copy, Apple explains that the "Force Touch" trackpad has "built-in force sensors that allow you to click anywhere and haptic feedback that provides a responsive and uniform feel" and enables a new gesture called "Force Click" which is a "click followed by a deeper press" for additional functionality over the "inertial scrolling, pinch, rotate, swipe, three-finger swipe, four-finger swipe, tap, double-tap, and drag capabilities" of the earlier trackpad.

The "Mid-2015" MacBook Pro notebooks can be identified by Model Identifiers in software -- MacBookPro11,4 for models with integrated graphics and MacBookPro11,5 for models with dedicated graphics -- but the earlier "Mid-2014" models share model identifiers with earlier systems and this identifier is not universally helpful as a result.

Internally, the 15-Inch "Mid-2014" and "Mid-2015" MacBook Pro models are quite similar. In fact, these models both use the "Haswell" architecture with processors of the exact same clockspeeds, have 16 GB of 1600 MHz DDR3L SDRAM memory that is soldered to the motherboard and cannot be upgraded after the initial system purchase,a proprietary -- albeit removable -- "blade" SSD, and batteries that are unfortunately glued in place.

There are notable differences between the SSDs and batteries between lines, though. The "Mid-2014" models have an SSD with a PCIe 2.0 x2 interface and a 95-watt-hour lithium-polymer battery that provides an Apple estimated eight hours of battery life. The "Mid-2015" models, on the other hand, have an SSD with a twice as fast PCIe 3.0 x4 interface and a 99.5-watt-hour lithium-polymer battery that provides an Apple estimated nine hours of battery life.

The lower-end models with "integrated" graphics in both lines have a Iris Pro 5200 graphics processor that shares system memory (and also has 128 MB of "Crystalwell" embedded DRAM on the CPU package to provide more memory bandwidth), but the higher-end models have an Iris Pro 5200 graphics processor and a second processor with dedicated video memory. Specifically, the high-end "Mid-2014" models have a NVIDIA GeForce GT 750M graphics processor with 2 GB of dedicated GDDR5 memory and the high-end "Mid-2015" models have a faster AMD Radeon R9 M370X with 2 GB of dedicated GDDR5 SDRAM. These "Mid-2015" models can support a larger external display -- up to 5120x2160 at 60 Hz -- via Thunderbolt 2.

The major differences between the 15-Inch "Mid-2014" and "Mid-2015" Retina Display MacBook Pro models are summarized below. Please refer to the specs page for the model of interest for complete details.

* The entry-level "Mid-2014" (MGXA2LL/A) and "Mid-2015" (MJLQ2LL/A) configurations only have a single Iris Pro 5200 graphics processor. This graphics processor has 128 MB of "Crystalwell" embedded DRAM on the CPU package, but these systems do not have dedicated GDDR5 VRAM. These models support two external displays up to 3840x2160 rather than one 5120x2160 display.

A more advanced trackpad, faster storage, and better battery life -- as well as modestly faster graphics with larger secondary display support for higher-end models -- are welcomed improvements, but the improvements are so modest that the "Mid-2014" models certainly remain well worth considering, particularly given discount prices on the used market.

Apple went with a new vendor in the 2015 model and only that vendors display works in your system MacBook Pro 13" Retina (Early 2015) Display Assembly. Trying to use other displays won"t work cleanly as the systems firmware won"t recognize them during POST. So your system will treat it as if its an external monitor. This will cause issues when you try using any of the startup commands and during wake from sleep. Some displays use a different length cable which may not work in your system and the iSight cameras have also been upgraded over time which can also cause issues.

Nine months after the Late 2013 MacBook Pro with Retina Display, Apple moved forward with more power and twice-as-fast Thunderbolt 2 technology in July 2014.

Apple offers a number of build-to-order options: Choose a 512 GB or 1 TB SSD, and boost the faster model even further with a 2.8 GHz quad-core i7 (4.0 GHz Turbo Boost). There is no way to install more than 16 GB of memory.

Mac Notebook Value for the College Student, Charles W Moore, ‘Book Value, 2009.08.20. “…Apple ‘Books represent the best long-term value for money spent, not to mention user experience….”

Finding the Best Values in Apple’s MacBook Matrix, Charles W Moore, ‘Book Value, 2009.07.21. With prices ranging from $999 to $2,499, speeds from 1.86 to 2.8 GHz, and sized from 13 to 17 inches, what’s right for you?

Just right: Papa bear, mama bear, and baby bear MacBooks, Charles W Moore, ‘Book Value, 2008.11.20. Some people like small and light notebooks, others prefer huge desktop replacements, but the best value tends to be in the middle.

Debunking the Apple Tax, Frank Fox, Stop the Noiz, 2008.10.31. “…no one else is offering the quality of computer construction that Apple offers in the same price range.”

Apple Trumps Microsoft in Making the 64-bit Transition Transparent to Users, Frank Fox, Stop the Noiz, 2008.09.18. To use more than 4 GB of RAM under Windows, you need a 64-bit PC and the 64-bit version of Windows. On the Mac, OS X 10.4 and later already support it.

Where’s the best MacBook value: Top, bottom, or middle?, Charles W Moore, ‘Book Value, 2008.04.29. When it comes to MacBook and MacBook Pro value, the top-end model is usually the worst value, but which model holds the sweet spot?

To AppleCare or not to AppleCare?, Charles W Moore, Miscellaneous Ramblings, 2006.11.20. Consumer Reports, which generally recommends against extended warranties, says AppleCare makes sense. But does it?

As long as the edges around the screen aren’t dented and there are no bends to the display, an LCD panel replacement is all that is needed for a cracked screen repair.

I am a full-service repair shop, specializing in component-level repair. This means I offer services that most shops will not offer because of the difficulty level. A lot of Apple repair shops will repair computers by replacing entire assemblies. For example, if you have a cracked LCD panel on your MacBook Pro, but otherwise your display assembly is fine, a lot of shops will replace the entire top screen assembly (lid, iSight camera, LCD panel, LVDS cable, hinges, etc) rather than just replacing the bad LCD panel. I work hard to replace just the broken components, making my repair services noticeably less expensive than most shops.

I have a few specialties that I am very proud of; display repair (component level repair including LCD panel replacement), logic board repair (component level repair including fuse replacement, LVDS connector replacement, and more), and data recovery (both level 1 recovery generally known as software recovery, as well as level 2 recovery generally known as hardware recovery). You can find examples of the services I offer below along with pricing and forms for starting service. If there is anything wrong with your computer that is not listed below, just let us know and we will get back to you with a custom quote! We repair everything on MacBook Pros.

MacBook laptops from Apple are some of the most beautiful and well designed – not to mention powerful, but just like everything else man-made they aren’t impervious to accidental drops, dings, and damage.

If you are unlucky enough to have a damaged screen, chances are pretty good you started to look into how much does it cost to replace a MacBook screen at the Apple Store – and the odds are pretty good you had a tough time hammering down concrete figures without bringing your computer into a store and having someone from the Genius Bar have a look. If you wanted to make an appointment with a Genius Bar, you can find that additional information here.

Replacing the LCD screen on a MacBook or iMac is not an easy task. You need to be very technically savvy and have all the right tools do the job. Not to mention that it is common for end users to cause expensive and irreversible damage to their mac computer trying to change the LCD. It is definitely not recommended. Just leave it to the experts!

To determine the exact cost of your Mac screen replacement, you need to identify your Mac model number first. You can find it on the back case. The photo below is from a 15” A1398 MacBook Pro.

Apple MacBook screens are a high-quality and very reliable product. Most of the time, they won’t go wrong for no reason unless they have been suffered from physical impacts or exposed to liquid.  You can easily notice a physical-damaged MacBook screen such as a cracked screen. You can see the image as well as the cracks. In this situation, you definitely need a MacBook screen replacement.

A completed MacBook screen assembly consists of an LCD panel, a webcam and a wifi antenna.  An older MacBook screen assembly also has a front glass and an in-built wifi card. If your screen display is working fine, only the webcam or the Wifi antenna is not functional; you may not have to replace the entire screen assembly. We can repair the faulty components for you to lower your repair bill. This type of MacBook screen repair will cost $100 to $200, depending on the MacBook models.

There are two types of MacBook Pro screens: retina screen and non-retina screen. A MacBook Pro manufactured in 2012 or before comes with a non-retina screen. The models include A1278, A1286 and A1297. A MacBook Pro manufactured in 2012 onwards comes with a retina screen. The models include A1425, A1502, A1398, A1706, A1707, A1708, A1989, A1990, A2141, A2159, A2171.

If you have a non-retina MacBook Pro screen, we can replace the broken front glass panel, broken or burned screen cable, faulty webcam or the faulty wifi card/antenna at a low cost without replacing the whole screen assembly.

If you have a retina screen, we can replace the broken or burned screen cable. Please note that this type of screen repair will only apply to MacBook models A1425, A1502 and A1398. The screen cables in the retina screen manufactured in 2016 onwards are not replaceable.

When you need to replace the MacBook screen, you may need to make a decision between using an Apple original screen or a cheaper third-party screen. We compare an Apple original screen with a third-party screen side by side shown in the following photo to help you better understand the differences.

The above two MacBook Pro A1708 were manufactured in 2017. Both MacBooks use the same background picture and set the brightness to maximum. The screen on the right-hand side is an Apple original screen; the one on the left-hand side is a third-party screen purchased online. You can tell the differences straightforward by the quality of the images. Here we discuss the technical details.

A MacBook screen consists of two major components, an LCD panel and a strip of LED lights called backlights. The LCD panel creates the image. The LED lights illuminate the image from behind the LCD panel. There are significant differences between an original Apple screen and a third-party screen as outlined here:

1. Backlight purity. Apple uses high-quality LEDs as backlight sources. The backlight is pure white. On the other hand, the backlight of the third-party screen is bluish. The bluish backlight degrades the vivid picture dramatically.

2. Backlight brightness. Even after eight years, Apple’s high-quality LEDs provide brighter lights and remain near the same brightness level. Low-quality LEDs not only produce bluish light but also have brightness degradation problems. The brightness of some third-party screens may only maintain half of the original brightness level after a year of use.

3. Photo sharpness. The Apple original screen produces a much sharper image thanks to the high quality of the LCD panel, as you can see on the right-hand side of the above photo.

Graphics card failures: The Nvidia 8800 graphics cards in these machine have a manufacturing defect which leads to graphical distortion on the display and or incomplete booting through. A very big problem on these machines, which lead to an extended repair program from Apple, which didn"t fix the underlying issue. The only fix we have for these is a temporary one called a Reflow. Given the age of these machines its only really worthwhile if you have a need for an older operating system.

Screen weakness: The metal surrounds on the LCDs of these machines often break at the sides near the hinges. This was an unforeseen weakness in the design of the LCD assembly. These days this fault is not worth repairing given the age of the machine.

Screen weakness: The display starts to come away from the hinge area. This was an unforeseen weakness in the design of the LCD assembly where the adhesive fails. This is repairable, but the costs (around £200 + vat) are more expensive than the machine is worth.

"Staingate": Delamination of the LCD panel. Nicknamed "Staingate", this is where the anti reflective coating comes off the LCD. Apple may still replace the screen for you for free. Check with them for details.

Battery swelling: The batteries in these machines are more likely to swell than earlier versions. There was an extended warranty for some of the machines in this series, you can check eligibility here on the Apple website. If not we can replace the batteries for a reasonable cost.

Keyboard issues: The keyboards on these units have a lot of problems. Random keys will stop working. Apple has now acknowledged this fault, and there is an extended repair scheme for it here.

Display issues (Stage lights effect / Flexgate): This exhibits as either bright spots along the bottom of the LCD panel, or complete failure of the LCD backlight. We have a service to repair this fault here.

Backlight Failure: This exhibits as the Mac not displaying anything on the screen, but still showing signs that it is booting up. It may work on an external monitor, and on older models with a white Apple logo on the lid you can shine a light through it and make out that there is an image being displayed on the screen. We have a dedicated No Fix, No Fee repair service for these faults here.
