Screen Resolution

4K, 5K, 8K… So many different resolutions, but what does it actually mean? Jackson shows us the difference in this weeks Tech Tip.

There’s alot of information these days talking about things like resolution and 4K and 8K and 5K and all these different resolutions, but what does it actually mean and what difference does it make when you’re purchasing a computer or a monitor?

Today I’m going to show you what difference it makes. Come and have a look here on this iMac. This iMac has what they call a 5K display. So it’s actually five times the normal pixels of your full HD screen. So obviously, picture quality is a big thing.

A lot of people will look at a 4K screen and say, “Wow, look at that image quality,” but it’s also about how much you can fit on the screen while still being able to see what’s going on. So for example, here we can look at what is the default scaling on this computer. You see how everything’s kind of bunched in together? If we go out a little bit to a true 5K screen, you see everything’s a little bit smaller but you can fit a lot more on the screen. So all of a sudden we’ve got all this extra room where we can drag windows around and have multiple things going at once.

The other end of the spectrum is if you have a really low resolution screen, it’ll look like this, where everything’s huge. It’s easy to read which could be great for some people, but you really just can’t fit as much information on the screen. So it makes it a little bit harder if you’re doing multiple things at once. 

So that’s why it’s really important to make sure that you choose the right screen, the right resolution when you’re buying a monitor for a PC or Mac.
