So there are many reasons you may want an external display for your Mac.
A Mac Mini or a MacPro, of course, needs an external display. If you have a MacBook then
you may want to place it at your desk and have an external display as either your second screen
or your primary screen. For an iMac you may simply want to have a second display and having
a second display can really enhance your Mac. It can double the amount of space that you've
got to move things around on the desktop and work with windows. Now Apple only has
one external display that they sell. That's the very expensive professional model. So most likely
you're in the market for a much cheaper, but pretty good quality, display that you
can buy at an electronic store or online in places like Amazon or just about anywhere.
There are many different factors that you need to consider. For instance there's physical size,
how big the display is. But also the Resolution which is not necessarily related to physical
size. Just having a larger screen doesn't mean you have more pixels. Then there's also the Connection
type. Cheaper screens may only have HDMI which is primarily used for TV's and then require an
adapter to go from your Mac to the screen. Also some of the more advanced screens will have
power through their connection. So if you have a MacBook you could plug it into the screen and not
only will it act as an external display to your MacBook but also provide power so you don't have
to plug it in in addition to connecting it to your display. Some screens also act as a USB
dock. So you can plug in other USB devices into the screen and then when you connect your MacBook
to the screen you see those extra devices just like they were plugged in directly to your Mac.
So say you could have a printer plugged into the screen and then when you plug into the screen
you not only get the display but the printer as well. Some screens have Speakers. Now this would
be very important say if you have a Mac Mini which doesn't really have real speakers. So
with the screen connected not only do you have the visual part of the screen but also
now you get stereo speakers. But if you're using it as a second display for an iMac then
you really don't need that or maybe you're just using a set of external speakers anyway so you're
not going to use the ones that are in the screen. Then, of course, there's Quality. You want to make
sure you get something that's going to last, something that also is going to be nice and
bright and is going to show good colors and things like that. Of course the one factor that ties into
the rest of them is Price. You have to spend more to get higher quality and to get better features.
So you have to kind of look at your budget and decide what it is you can afford.
First let's talk about size. So there are three main sizes that you will find when looking for
screens. 24", 27", and 32". There are other sizes as well and sometimes 27" screens are called 28"
screens and things like that. But basically most screens are going to fall into those three sizes.
So here's a 24" screen. Of course I'm using American measurements here. Note that these
measurements are from one corner to the other so it's not the width or height, it's the diagonal
measurement. You can see if you go to a 27" screen it looks a little bit bigger. Actually it's a lot
bigger because, of course, you're getting the area not the width and height. If you go to 32"
it's even much bigger than that. If you can get to a computer store that sells screens at some point
and look at the different sizes and get an idea of what these are. 24" really seems quite small. 27"
kind of seems normal and 32" seems quite large. So you probably don't want to buy these blind.
You want to actually see these screens even if they are not the exact models you're looking at,
at least see the sizes so you get an idea of what it is you have space for and what you want.
Now Resolution of the screen is a different matter. Now awhile ago
most screens would have been about 1920 x 1080. This is sometimes called HD or 1080p. What you get
here are basically 2 million pixels. Now years ago Apple introduced what they called Retina displays.
That's where there are 4 pixels, a square of 4 pixels, where there used to be just one.
So the screen sizes are the same but you have more pixels, twice as many wide and twice as many high.
So when you go from 1920 x 1080 to 3820 x 2160 notice the number of pixels goes up four times.
So now you have more than 8 million pixels. This is quite an improvement and quite a
difference. Pictures will display using all of these extra pixels. So they are going to look
a lot closer to say a printed photo than with a 1080 screen. Text will look a lot clearer. It's
hard to illustrate. But if you look say under a magnifying glass at text on a 1080 screen you may
see something like this. Now, of course, shrunk down your eye is just going to see the word. But
here's what it looks like on a retina display, also called UHD for ultra-high definition.
You could see that there are a lot more pixels here. This is going to look a lot
smoother to your eye at the regular size. So even while at first it may not seem like there is much
of a difference, I mean you could read the words in either case. It's going to mean that the text
looks a lot smoother. It's going to have a lot less eyestrain. It's going to look a lot better.
Now all new Macs, the MacBooks, the iMacs, they come with a retina display. So you're going
to see the equivalent to a UHD screen. So if you want the real Mac experience
don't bother with the standard definition screens anymore. Only look for UHD or retina displays.
Another things to consider is the Connection. So on your Mac you have one of four different kinds
of connections. You could see those here on the left. You've got HDMI available on some older Macs
but none of the current ones. On older Macs also you're going to have ports that look the same but
they're slightly different. Very older Macs are going to have mini DisplayPort ports. Newer Macs
will have Thunderbolt 2. They look the same and indeed Thunderbolt 2 can carry mini DisplayPorts.
So if you have either one of these two all you need is a mini DisplayPort cable. It doesn't
matter if a Thunderbolt 2 or an older mini display port. Then you can go from there to your screen.
Now all current Macs have USBC also known as Thunderbolt 3. This also includes a mini
DisplayPort. So you can connect a mini display port cable to this USBC Thunderbolt 3 port. Of
course it has to match the physical type of USBC. So it's a different kind of cable. But going from
USBC Thunderbolt 3 to a screen that has a mini display port is a direct
connection. Your Mac is actually sending mini display port signals out right to the screen.
On the right you'll see screen tab. Just about any screen you see now is going to have at least HDMI.
But if that's all its got it's probably not a great match for your Mac.
A lot of screens will have mini DisplayPort or DisplayPort. I don't have a symbol for it here
but it's a larger port. It's the same thing as a mini display port. It carries the same
information. But it's a different shape. A lot of times when you get a screen that has the older
full size mini DisplayPort it also comes with a cable that goes from the full size DisplayPort
to mini DisplayPort on the other end. Then numerous screens will also have USBC.
So let's take a look at some combinations here. If you've got a Mac with HDMI
and you go to a screen with HDMI you can go directly with just a simple HDMI connector.
Now if you've got something that's got USBC, like a newer Mac or even an older Mac with
Thunderbolt 2, then you can get a cable that goes from those to the HDMI port on a screen. However,
I put X's through this because you shouldn't do that! Now it technically works and on some screens
it may work just as well as anything else. But on other screens it's not going to work well at all.
Time and time again people have asked me about problems they are having with their
external screen and I find out they are going from either USBC or Thunderbolt 2
to HDMI on the screen even though the screen has a DisplayPort or mini DisplayPort port on the back.
Just go directly from the mini DisplayPort or Thunderbolt 2 to the DisplayPort port on the
back. Keeping it all in DisplayPort that's kind of the computer language of talking to a screen,
that always gets you the best results on the Mac. Trying to go to HDMI, just because
you happen to see HDMI on the back, that could often leads to problems. Only use HDMI if that's
the only possible way to connect with the screen. Of course, avoid any screen that only
has HDMI. Go for at least something that has DisplayPort or mini DisplayPort on the back.
Now you can also, of course, go from USBC Thunderbolt 3 port on all of the current
Macs to either a DisplayPort on the back of your screen which is great and will work just fine.
But if you're going directly to a USBC port that some of these have then you're going to get some
extra benefits. For instance, that may also carry a USB signal which means that there are USB ports
on the back of the screen you can use the screen as a hub, as a dock in other words. So you can
connect other things to it. Then also you get some other things like if there are speakers then those
speakers would show up on your Mac with just that one cable. In addition, you can often get power
this way. So if the screen supports it it will send power back to your MacBook. So this is only
important, of course, if you have a MacBook. If you have an iMac and this is the second display it
doesn't matter. But for a MacBook you can connect one cable if you go from the Thunderbolt 3 port on
your MacBook to a USBC Thunderbolt 3 port on the screen and you'll get power back to your MacBook
and also usually get other USB connections that are on the back of the screen. So it acts as a
dock as well. Even speakers too. So one cable can carry just about everything that you need.
So let's look at some examples. Here is a very inexpensive Acer display. You can
see it's $130. It is a 24" screen. So it's a very small screen compared to everything else and it's
1920 x 1080. So a 1080 screen. So you're getting a good price on this. It's pretty cheap. Hard to
argue with how cheap it is. But you're not going to really get the full potential of your Mac
with something that's standard resolution and it's going to be pretty small as well.
If we look at the back here we could see that it has basically some older type connections
and a HDMI connection. So you need to get a mini DisplayPort or Thunderbolt or USBC
to HDMI cable which is going to cost a little bit and then that's all you'll be able to use
to connect to the screen. It will be fine because the screen is so low resolution it's really not
going to matter. So this is an example of one of the cheapest ways to connect. But if you're
spending the money to get a Mac then at least spend a little more money to get a decent screen.
So here's the Samsung screen that is 27". So much more normal size. But it's still
1080. So you're still going to get the standard resolution. It's a little more expensive for the
larger size and it's better quality. Also notice that in addition to the HDMI it has a DisplayPort.
So you can connect directly from a mini DisplayPort, Thunderbolt 2 or Thunderbolt
3 port with the right cable directly to this and you'll get good results. But you're still
at 1080p. It also works as a USB Hub so you can connect USB cable to it and now you've got
some extra USB ports. But it carries no power here so you're going to have to also plug in
your MacBook if that's what you're using with this. Of course if it's a MacMini or an iMac it
doesn't matter. So this is a better option for a little more money but it's still doesn't get you
the really good resolution that you should be using with your Mac.
Here's another option and this one is definitely more expensive.
But you're getting UHD. So you're getting the equivalent to Apple's retina display. So you can
see here it's 3840 x 2160. It also has a USB type C connection. So you'll be able to plug that cable
directly into say a MacBook. If you look down here at some of the specifications you'll see
it delivers 60 watts of power. So you want to check that against whatever you've got. So, for
instance, if you have a MacBook Air and you look at the tech specs for a MacBook Air you'll see
that under Battery & Power it comes with 30 watt power adapter. So certainly the 60 watts
delivered here is going to be more than enough. Even if the power adapter is a little bit more,
like the MacBook Pro is 61 watts, 60 watts will be fine to fully power the MacBook Pro. So you'll
be able to connect your MacBook with one cable and get the screen and power at the same time.
So those are just some examples. Models switch out all the time so perhaps by the time you see this
there will already be different model numbers and all of that. So you just have to search
for different displays, read the specs. It can be confusing. There can be a lot of different ones to
look through so it takes a little bit of patience to find exactly the one that fits your needs.
So here are my recommendations for all the things I talked about at the beginning here.
So Physical Size: I wouldn't consider a 24" one unless you have a really good reason that you
want a tiny screen. Go with 27" for a standard size or 32" if you want something even larger.
Then for Resolution: don't mess with anything less than 4K. There are screens that are
5K and even higher nowadays. But they are going to cost a lot more. 4k is kind of the standard at the
moment. So look for 3840 x 2160 for a screen. Connection Type: Always go with a screen that
has DisplayPort for standard screens like adding a second screen to your iMac or
connecting something to your MacMini. But if you're connecting a MacBook make sure you're
getting power back through the connection which is usually specified as USBC or Thunderbolt 3.
As for whether it's a USB dock it's probably not that important. I mean usually there are not too
many USB ports on any of these. So if you have a lot of external devices you're going to get
a USB Hub and they're pretty cheap anyway. But if it's something you want take a look at that.
Speakers: Really only if needed. It's easy to get external speakers which are probably
always going to be better than any built into a screen. But if speakers aren't that
important to you but you still kind of need them, you know to watch videos and things,
then that may be something you want to look for. How about Quality: People always ask me about
brands and, of course, I only have experience with the brands I've used in the past. I can tell you
that LG makes pretty good screens. So does Samsung and so does Dell. As a matter of fact a lot of the
screens actually have some of the same internal parts. I know Samsung makes a lot of the displays
that Apple has used over the years and LG is probably putting some of those same displays
into theirs. The are other brands as well but I've never really used them and I don't really
consider them when I'm shopping for screens. So if you're looking for brands those are the three
that I can say are usually pretty good but it doesn't mean the other ones are necessarily bad.
Price: Price is really subjective. For some people spending $1500 for a really good screen because
they do graphics work. It's totally worth it and easy to justify because they make money using
their Macs. For other people they want to spend as little as possible and stick to $400 or less.
Another thing I would suggest is to make sure it's pretty easy to return a screen in case you get it
and something is wrong with it because I'd say 95% of the time everything is fine but it's a pretty
high error rate for getting screens with dead pixels or maybe they don't work quite right with
your model of Mac. So you want to make sure it's easy to just bring it back so you can try another
one. If it's a local store ask them if it's easy to return and just bring it right back to them.
Sometimes it is and sometimes it isn't. If it's a online store make sure it's really easy to take
it somewhere to return it because, of course, shipping a screen back can be a real hassle
because they are so large. So if you're in the market for a screen for your Mac
I hope this helps you pick one out. If you have any questions ask them in the comments below.
