What is retina display wifi

I’m trying to decide whether to buy ipad or cheaper tablet. What is retina display and what is diff betw ipad and mini with only wifi? What is mini missing?

I’m trying to decide on tablet to buy — what is the difference between mini and ipad? What is retinal display? Why do some have wifi only and some have wifi cellular? Why would I need cellular?

I keep hearing that apple computers don’t pick up viruses like pc (of which I have had my fair share) so that is why I am considering — but there are some really attractive deals for cheaper tablets.

Then, you should go to your nearest Apple Store and look at the screens, the size.

You need cellular if you want to access the internet when you are not near WiFi.

the main difference between the iPad and the iPad mini is the size of its screen.

The larger iPad or iPad Air has a screen diagonale of 9.7 inches, while the iPad Mini has only 7.9 inches. The first generation of the iPad mini has a resolution of 1024 x 768 pixel, while the 2nd generation has a four times higher resolution of 2048 x 1536. This resolution is also used on the larger iPad and iPad Air. Out of those iPads with the 9.7 inches display diagonale only the second generation iPad does not have the higher resolution. iPads with the afore mentioned higher resolution are called Retina-iPads. See http://store.apple.com/us/ipad/compare for a detailed comparison of all iPad models available through Apple.

Both the iPad and the iPad Mini come in two variants each. One variant is WiFi connectivity only, the other is WiFi and cellular connectivity. You would need cellular connectivity if you want to have internet access on your iPad where no WLAN is available (e.g. while travelling on the highway and using the iPad as navigation aid). Additional charges might apply from your cellular service provider.

Yes considering viruses only, iOS and OSX are far less threatened as computers and / or tablets running other systems. Yet, these days, viruses are no longer the only security concern. These other threats make much less difference between the operating systems and are therefore as dangerous to Apple computers as they are to other systems.

A simple answer to a loaded question? Not here!

1. For starters, I can’t recommend the newest iPad AIr or iPad Mini. The previous versions worked perfectly though if you want to go the Apple route. That alone will save you a few bucks. Best Buy undercuts Apple prices by a few $$ and has bonus sales around this time of year.

2. You get what you pay for. I like the Samsung Galaxy Tabs a lot. Good hardware and software. App store has plenty to offer. You also have size options like you do with Apple. Since I have the Galaxy S3 phone, the Galaxy tabs are very familiar. The Surface (smaller one) is big for a tablet, it works great, but is subject to the frailties that plague PCs to some degree. I don’t like the keyboard, but do like the kickstand. I don’t know about the availability of Apps for the Surface, I think it may be a major downside to the device. The Surface is not cheaper than iPad either. As for the cheaper Tablets, they will be in the landfill before Apple introduces a new gadget (that’s pretty often. ) The Kindle is still primarily, an eReader.

3. Wifi or wifi and cellular — If you have a smart phone and can tether a tablet, you don’t need cellular on the tablet. With more places offering free hot spots, wifi is more than adequate. ( I use very little cellular on my mini)

4. iTunes and the App store; I will start by saying I am cheap. If the App isn’t free, it has to be really valuable to me or I won’t buy it. I paid for Pages on my iPad 2 years ago and I bought a password wallet that syncs on all my devices on all platforms. Aside from that I buy music to add to the CDs I imported to iTunes. If you don’t like iTunes and don’t want to use it, keep looking at android tablets.

5. ios 7 — Never has Apple made such a big deal and been so poorly prepared to introduce a new ios. It has devoted Apple heads steamed. I count myself one and have had no problems with my devices, educated user I hope, or just really lucky.

6. I really USE my tablet. I use it for work, for financial management and communications. I rarely have to resort to the desktop as almost everything is possible on the iPad. I love it’s portability! Documents and data flow back and forth with the cloud I never worry about losing anything or finding anything. Photos download automatically from my Android smart phone with Dropbox App and are instantly available to load on all devices.

7. If you are a big PC hacker type, the switch to ios is culture shock. The first time on the new iMac I was at my wits end trying to navigate. I only had to stop working so hard and it all fell into place.

I have the iPad 2, (wifi only) and the first mini (with 4G LTE) and I had a 4th generation iPod touch and now have a 5th Gen iPod touch (which I really like a lot). My son has an iPhone 4S and the iPad with retina display. Both my sons have had iPods through the years.

My 50 year old eyes prefer the bigger screen of iPad 2 and typing is much easier. But I love the portability of the smaller tablet, so one for home, one for the road. Thanks to iCloud what ever is on one is also on the other, documents, data, contacts, etc. Retina display, my son has it, I don’t, I can’t say I miss it. It does make pictures look better, if you are a photo person, the retina display is worth it.

I also have transitioned from PC to Apple completely, I bought an iMac 4 years ago and it is as fast as it was on day one, no crashes, repairs, viruses. I just bought a Mac Mini and I also use Apple Airport extreme for router and I have an Apple TV (the only disappointment, I prefer the Roku 2)

I’m sure that was more than you asked for. 😉

What Is Retina Display?

Sam Costello has been writing about tech since 2000. His writing has appeared in publications such as CNN.com, PC World, InfoWord, and many others.

In This Article

Retina Display is the name for the high-resolution screen technology Apple uses on various models of the iPhone, iPad, and other Apple products. It was introduced with the iPhone 4 in June 2010. Read on to understand what Retina Display is, how it’s different from other screens, and what products use it.

What Is Retina Display?

Retina Display smooths the jagged edges of the screen’s pixels and makes images seem more natural. Retina Display gets its name from Apple’s claim that screens made using the technology are so sharp that it’s impossible for the human eye to distinguish the individual pixels that make up the screen.

The benefits of the technology are particularly visible when looking at text. On Retina Display, the curved edges of fonts are substantially smoother than on previous display technologies.

A Retina Display’s high-quality images are the result of several factors:

• A high density of pixels that make up the screen.
• A high contrast ratio that creates brighter whites and deeper blacks.
• In-Plane Switching (IPS) technology that improves the angles from which the screen can be viewed.
• Chemically treated glass over the screen and LED backlighting improve the quality of the image.

The Two Factors That Make a Retina Display Screen

There’s no single answer to the question «what is Retina Display resolution?» For example, not every device with a resolution of 960-by-640 pixels has a Retina Display, even though that’s the resolution of the iPhone 4, which has a Retina Display screen. Instead, a screen has to meet two criteria to qualify as a Retina Display screen: pixel density and the distance from which the user views the screen.

Pixel Density

Pixel density is how tightly packed the screen’s pixels are—the greater the density, the smoother the images. Pixel density is measured in pixels per inch (PPI), which is how many pixels are present in one square inch of screen. This metric is based on a combination of the device’s screen resolution and its physical size.

The iPhone 4 had 326 PPI due to a 3.5-inch screen with a 960-by-640 resolution. This spec was the original PPI for all Retina Display screens. That changed as later models were released. For example, the iPad Air 2 has a 2048-by-1536 pixel screen, resulting in 264 PPI. That, too, is a Retina Display screen. This is where the second factor comes in.

Viewing Distance

Viewing distance refers to how far away users typically hold the device from their faces. For example, the iPhone is usually held relatively close to the user’s face, while a MacBook Pro display is seen from farther away.

This matters because the defining characteristic of a Retina Display is that the human eye can’t distinguish the pixels. Something that’s seen up close needs a greater pixel density for the eye not to see the pixels. Pixel density can be lower for displays viewed at a greater distance.

Other Retina Display Names

As Apple has introduced new devices, screen sizes, and pixel densities—and made improvements to the display technology—the company began to use other names for different Retina Display types. These include:

• Retina Display: Used on the iPhone 4, among others.
• Retina HD Display: Used on the iPhone 6 Plus and others.
• Retina 4K Display: Used on the 21-inch iMac.
• Retina 5K Display: Used on the 27-inch iMac.
• Retina 6K Display: Used on the Pro Display XDR screen.
• Retina LTPO Display: Used on the Apple Watch Series 6.
• Super Retina HD Display: Used on the iPhone X and iPhone XS.
• Liquid Retina HD Display: Used on the iPhone XR and iPhone 11, among others.
• Super Retina XDR Display: Used on the iPhone 11 Pro and Pro Max and iPhone 12 series.
