Archived from the original on March 12, Coding Horror. Retrieved 18 September June 9, To get the most out of the videos you watch, your television's resolution should match the resolution of the video. So, even though televisions come in different sizes, the industry needs a standard screen resolution to match the video produced with the resolution of the television. It doesn't do any good to have a higher resolution for a bigger television when the picture on the screen is shown at a lower standardized resolution.

So, 4K is an important standard for the television industry. But, tablets are used for much more than streaming videos from Netflix and Amazon Prime. So, in terms of a tablet, the 4K designation has less meaning. Does that make Retina or True Tone or both a better option?

A retina display is a screen with a pixel density high enough that individual pixels can no longer be discerned by the human eye when the device is held at a normal viewing distance, according to Apple. The normal viewing distance is an important part of this equation, because the closer you hold the device, the smaller the individual pixels need to be before they become indistinguishable from one another. Apple considers the normal viewing distance of a smartphone to be between 10 and 12 inches, and the normal viewing distance for a tablet is around 15 inches.

The Retina display distinction is important because any higher screen resolution doesn't provide extra viewing benefits. Once the human eye can no longer distinguish individual pixels, the display is as clear as it can be. And, higher screen resolutions require more graphics power, which depletes the battery faster. So exceeding a Retina display can actually detract from the device. The confusing part about a Retina display is that it comes with many different screen resolutions.

A 4K display is generally a x resolution regardless of its size, but a Retina display's resolution usually changes based on its size. The 9. The A PPI of around or above is key to achieving that Retina display range in tablets. Apple thought that keeping the resolution the same from a compatibility standpoint was more important than the extra drain on the battery, but the display itself would look about the same with a smaller resolution.

In terms of buying a tablet , the 4K designation should only be a concern if you primarily use the device to watch television and stream video. The real number to look for is the display's pixels-per-inch PPI. PPI is based on screen size and screen resolution. Most tablets now display it in their specifications. You can see a list of broadcast TV networks and cable providers with apps for the iPad. A 4K resolution on a tablet should generally be considered only on tablets that measure 12 inches diagonally or more.

Smaller tablets with a 4K resolution are jumping on the bandwagon for a display that uses more battery power but doesn't provide any clearer resolution than an iPad. This is the same resolution as the 9. Samsung marketed this Galaxy Tab S3 as a 4K tablet because it can accept 4K video even though it cannot output it onto its display. This basically takes marketing buzz words into the bait-and-switch area.

It also means you should be skeptical of any tablet referring to itself as 4K. While 3D TVs have proved to be a bit of a fad, 4K television sets are likely here to stay, but it may take longer than some think for it to become the true standard. It takes more space to store a 4K video and, more importantly, it takes more bandwidth to stream 4K.

It currently takes around Megabytes-per-second Mbps to stream p high definition video. If you take into account the need to buffer and deal with the varying speeds of Wi-Fi, 8 Mbps would be more ideal. Currently, it takes between 12 Mbps and 15 Mbps to stream 4K video, with the ideal connection being around 20 Mbps.

For many people, that would take most of the bandwidth they get from their internet provider. Even those with 50 Mbps connections would feel a major slowdown if two people on their network tried to watch a 4K movie at the same time. While it might be possible to work around the issue, a company like Netflix or Hulu Plus would see a huge increase in the cost to stream video.

There are several reasons for it such as:. However, in comparison to a retina display, the downside to an AMOLED display is that the colors may look more saturated at times which may make the images look unrealistic.

It also makes the screen more vulnerable to image burns. There is a common belief among people that a retina display may cause harm to the eyes. Well, there are quite a few complaints about eye issues, but several studies and researches have shown that it is actually not due to the retina display itself but, in fact, it is for the blue light emitted by the screens. Remember, a retina display is so designed that the resolution itself of it is safe because it is the amount that the human eyes are traditionally used to.

As said earlier, the specific element that does the magic is the Pixels Per Inch of the display, which is approximately PPI. Since the human eye can detect a pixel density of around pixels per inch and the retina display comes with a pixel density, this improves the quality of the image. This is because the pixels are almost invisible to the users and have smoother lines and higher resolution.

This makes it easier for the users to read the texts on the screen. On the other hand, it also offers a far better and cleaner user interface. Due to the improvements made in the technology and design of a retina display, it offers a wider viewing angle than those devices without it.

This means you can see the images clearly from any side of it and not only from the front of the screen. The Retina display comes with a better and wider color gamut which enhances the color saturation of the screen as well as the images displayed on it.

The users will have a much better viewing experience while using a retina display. This is because these screens have a higher contrast ratio between different colors, which means the images will have better color accuracy, reproduction, and presentation.

Screen real estate. The high resolution of the retina display provides more real estate of the screen to fit in more info on it and still keep them legible. This makes the screen more useful for not only the users but also for the app developers as they can make the most out of the screen space available. A retina display allows better consumption of content whether it is simple images or videos, graphics or websites, eBooks or web articles, and even games.

This feature makes these types of high-resolution displays best suited for creative professionals who are into photo editing , graphic designing , and more. It is all due to its ability to reproduce images with more and finer details. A retina display will cause less eye strain even if you spend a lot of time in front of your computer.

This is due to its ability to produce sharper images and you will not need to put an extra effort or strain your eyes to focus on a specific area on the display. This is a much better technology that promises better outdoor visibility even under direct sunlight. In this high-end emissive display technology, the individual pixels are turned off to demonstrate the blacks in a given area.

Though the initial investment on a retina display will be more in comparison to an ordinary display but it will provide more value in return down the road. It also consumes less energy making it more cost efficient. Laptops, or any other product with a screen for that matter, that comes with a retina display is much more expensive.

Though the high pixel density is good for the images or the eyes, there are quite a few specific web contents or apps that cannot make the most out of it because these are not optimized fully. Therefore, the images of these websites and apps are not adaptable and are not reproduced accurately and look slightly distorted.

It also looks a bit pixelated on a retina display. Sometimes, the high contrast ratio of the retina display causes the backlights to leak out. This is because the pixels on the darker areas of the images are turned off selectively, thanks to its emissive technology. The pixel response time may be slower at times as well, especially in those retina displays on low-end devices. However, the liquid retina displays do not come with this drawback because the hardware is much better which improves the refresh rate of the display to make it as high as Hz.

The answer actually depends on two things - your budget and the time you will spend in front of it. If you can splurge on a 4K retina display, it will be much more comfortable to your eyes, even if you look at it for a long time. It is worth the money you pay due to its perfection which will increase your productivity as well as your multitasking potential. Well, certainly yes, especially when quality matters. The retina display will not only have a higher resolution than a full HD screen but it will also offer much better color accuracy, viewing angles, and stock calibration as well.

This will help you immensely when you edit your photos on your laptop. Well, the retina display as such will not cause any direct harm to your eyes, much as the LED backlight and the blue light will. If you are sensitive to them, it may be uncomfortable for you, causing eye strain and sleep disorder.

Having a retina display in your laptop is a great thing because it promises more comfortable viewing. However, these are costlier than other superior displays, and whether you will go for it or not will depend entirely on your personal preference and budget. For example: The display comes with a larger pixel density. This makes the images clearer, denser, crispier, and more vivid. It also doubles each of the user interface widget, both in height and width, in order to compensate for the reduced pixels.

This equation offers better picture quality by offering a few significant benefits such as: The CPU will see a very small portion of the data which helps it in calculating the comparative positions of each element much more efficiently and quickly and, The GPU will then find it easy to render these specific elements with much assets of better quality and color reproduction which makes the final output much clearer and sharper.

It may vary significantly depending on a few specific factors such as: The size of the display of the device and, The distance from which a user will typically view the screen. Now you will get retina displays that have a: Larger screen size Better contrast ratio and PPI count.
