Video Description

One of the most common output devices are the monitors of our computers, otherwise known as display devices. They allow us to see exactly what is going on in our operating system whether it be through a screen or projector. You'll learn display devices are any type of screen that allows us to view output from the computing system. They are plug and use devices with specific connection inputs and typically a variety of inputs so you can determine which you prefer to use. We'll break down one monitor to show the connections and examine the types of devices its compatible with. That's important because the type of device it connects to is determined solely by the type of video card the motherboard's holds. If you have the right type of connectivity and video card, you can connect any type of display device, from small desktop monitor to large screen TV. Projectors are display devices that allow us to display enlarged version of small visuals images. They can be displayed on projection screen, specialized display devices or even a wall or small screen as in a pocket projector. Projects come in a variety of types, can be complex in the types of resolution and size optimization or image clarity features, but generally have standard output connectors. Since they are designed for myriad purposes and come in equally varied sizes, you must research type and size against the purpose of its use and assess compatibility if using with a computing system.

00:04
moving on to a different type of output device our our our display devices. Now, our display devices, they're also considered output devices, but more often you'll just hear them under the category of display devices. First thing that comes to mind typically are going to be our standard screens. Everything from R C R T monitors to our
00:23
LCD monitors are plasma screens that we have in our house,
00:27
any type of screen that we can connect to our computer and we can use it. Toe output video is gonna be one of our display screens. We talked a bit more about our specifications for our particular screens in an early in an earlier video in an earlier episode. But
00:44
we just want to make sure that we know that our screens, typically you're just gonna be simple plug and use devices. We're going to connect them with one of our many different types of connections. V g et h d m i D v I etcetera, and use those different connections owner to use the device.
01:04
So this particular display
01:10
we can actually removed from our stand
01:14
and we'll notice on the bottom has a few different inputs here. It actually has our Devi aiport
01:19
V G A ports
01:22
power input
01:25
stand USB input.
01:27
Now these US B inputs are actually connected to the USB hub on the side of the screen. But what we're more focused on for our display devices are going to be these two. Having these two connections here, let us know that this screen will work with our V g A connections or our Devi I connections. That gives us a little bit more
01:46
flexibility when we're selecting which monitors we want,
01:49
because we may just We may only have V g a available on our computer now, but
01:55
if we upgrade to Devi I in the future, if we get a new video card or if we buy a new computer, we can still use that same monitor just with a Devi I cable. So it makes it a little bit more promising to us than just having a computer with just one type of connection. So we always want to make sure that we're checking that out before we purchase our screen. Before we purchased the monitor, we don't want to
02:14
purchase a monitor
02:15
with only Devi I and then our computer only worked with V G a again. Then we'll have to doom or investing there in order to make the two compatible.
02:23
So
02:24
we want to make sure that we know what type of monitor were using. We want to know the specifications and the size and the information about how those monitors work. And then we can use that as our display device. And again, not just our small desktop screens, but everything from our small death stop screens all the way into our
02:43
extremely large 50 inch plasma screen television that we plug our computer into to watch Netflix on our television. All of those are considered display device screens, and all of those could be used with our computers if they have the right type of connections and if they have the right type of connectivity between two, so go ahead and at our screens
03:02
to our list. Here,
03:04
in addition to our many, many different types of screens, we also have our projectors.
03:09
Now, our projectors are
03:13
very useful tools,
03:15
huh?
03:15
They allow us to create an image that could be a lot larger than what a simple screen is going to provide us. We have a small portable projector here. Nothing. Nothing too fancy just gets the job done. And
03:29
this allows us to connect the either R V g A or s video. And we also have a standard component input here.
03:38
Now, using those inputs. All this does is just support video. It doesn't have any speakers on. It doesn't support any type of audio out. So we would need to use additional audio perhaps, um, external speakers that we plug in to our computer or using safe the laptop. And it has its own sound. We can use that sound, but we want to make sure that it's suitable for this situation.
03:59
Projectors have
04:00
a lot of different types, a lot of different sizes, and they become they can be very expensive, especially for the hiring projectors say that they'll use it. Concert or sporting events are very large demonstrations. Those projectors can be very costly and they can be very complicated to set up. But
04:18
again typically will just see them using standard
04:21
output connectors like we would use on a screen, except they're plugged into our project.
04:26
Now our protectors, we want to make sure that when we're setting them up. We're using the proper zoom, the keep proper keystone and the proper focus. These can all be found as settings or knobs on the computer that allow us to change the way the images on our screen so that we can optimize the the size of the image as well as the clarity of the image.
04:45
Keep in mind,
04:46
we're actually even encountering some projectors now that we see as Little Mini marketed his pocket projectors that we can actually even plug into our phone and use them to display a small image on on a wall or on a small screen.
05:01
Now, depending on your situation, you may need one that's larger. You may need one that's all the way down to the size of a pocket pocket projector, but it's always best to do your research, determine what your needs are and then use that research to make the best purchase and make one make a purchase where your projector is going to be compatible with the computer that you're using
05:21
in order to display your images and use that out.
05:25
But device. So thank you for joining us today. Here at cyber a dot I T we talked a bit about some of our different types of input moments. A media output in display device. It's hopefully this information was helpful in getting yourself either prepared for an exam or just learning some more general knowledge about these different types of devices. My name is Anthony.
05:45
Thank you for joining us and hope
05:46
you'll see us next time here on cyber. Got I T.
