So What Is Apple Retina Display?

You’ve seen and heard Apple talking about the iMac with 5K Retina display, the MacBook Pro with Retina display, and so on. But what is a Retina display, and why should you care?

Retina displays are high-resolution screens on which graphics are extra sharp and text is super crisp.

The LCD screens used in Apple’s displays use a grid of “pixels”—the smallest possible dot whose color can be controlled—to create all the text and graphics you see. Today’s iPhone 7 Plus screen can fit 401 pixels into each inch. As pixel density goes up, the pixels get smaller. With a 72 ppi (pixels per inch) screen, it’s easy to see each individual pixel in a character, but the higher the pixel density, the harder it becomes to pick out separate pixels.

When Steve Jobs unveiled the iPhone 4 in 2010, he said that for a screen that’s held 10 to 12 inches from the eye—about the distance at which many people hold their iPhones— the human eye can’t resolve individual pixels if it’s about 300 ppi. At longer distances, it becomes harder to discern small details, so most people won’t be able to pick out pixels on a screen viewed at arm’s length, such as an iMac display, if it’s about 220 ppi.

So Apple says a “Retina display” is any screen whose pixel density is high enough that someone with 20/20 vision cannot see individual pixels at the standard viewing distance used for that device.

For the Mac this is about 220 ppi. Larger iPads have a pixel density of 264 ppi, and the iPad mini checks in at 326 ppi. From the iPhone 4 through the iPhone 7, pixel density stayed at 326 ppi, but the iPhone 6s Plus and iPhone 7 Plus are 401 ppi. The tiny Apple Watch screen is about 330 ppi.

If you suffer from eyestrain, reading on a Retina display will likely be easier and less tiring, since the words will be clear and crisp, without any of the fuzziness on the edges that you see on lesser displays.

Last, the words “Retina display” are an Apple trademark. So you won’t see any other manufacturers claiming that their products have Retina displays.

Now Upgrading Windows PC and Macs with Solid State Drives

You can save a ton of money by upgrading your current PC or Mac with a small but mighty SSD upgrade. The reason most computers slow down is because the hard drive can only read and write data at 50MB per second. This is equivalent to rush hour traffic at 5pm anywhere in the UK. The solid state drive is like having 8 lanes open with no traffic. Files read and write data at over 550MB per second. Over a 10x performance increase.

Keep Your Mac or PC Running For Many More Years!

Improve an Old Mac’s Performance with an SSD

Mac SSD upgrades Horsham

We understand. That MacBook Pro you bought a few years back doesn’t seem like it should need replacing, but performance has started to lag, and you don’t have the money for a shiny new Touch Bar model. Adding RAM up to 8 GB can help, but the best bang for your buck in terms of performance comes from swapping your Mac’s hard drive for a solid-state drive, or SSD- Contact us for Mac SSD upgrades Horsham.


What’s an SSD? As the name implies, it’s a storage device that has no moving parts—no spinning disks and no read/write heads skimming along just a few nanometers above the disk surfaces. Instead, SSDs use flash memory, a type of non-volatile memory whose chips retain data even without power.

Mac SSD upgrades Horsham

SSDs have two huge advantages over traditional hard drives. The first is reliability, particularly in laptops that are picked up and set down many times a day. Drop your MacBook Pro on the desk a little too hard, particularly while it’s on and the drive is spinning, and that read/write head could hit the surface of the disk—the very definition of a hard disk crash. With no moving parts, SSDs aren’t nearly as vulnerable to physical damage.

But the second advantage is why SSDs have become so popular—they’re fast, really fast. One SSD vendor advertises them as up to 92 times faster than hard drives. Obviously, the specifics can vary quite a bit, but in system benchmarks, swapping an SSD in for a hard drive can improve overall performance by 50 percent or more. Drive-intensive activities like booting see the most benefit—you’ll be shocked at how much faster your Mac boots with an SSD.

SSDs are fast and reliable, but the tradeoff is that they’re much more expensive per gigabyte and can’t hold as much data. For many Mac users, the best combination is an internal SSD for booting, running apps, and holding frequently used data, and a big external hard drive for less important data and archives. And, of course, backups are best sent to a big external drive, since capacity is more important than performance with backups.

So if you’re trying to goose the performance of your older Mac, look into an SSD.
