this module, We're going to go over the various different types of display connectors.
00:13
Ah, the more connectors for LCD Mars, they're connected to PCs. Ah, use a standard analog connector such as shown here. The analog one is the blue end.
00:25
There'll be blue on both ends for analog connections. The new one is Devi I, which can also do digital. In this case, we're converting from analog to digital. With this cable right here,
00:42
there's another new kind of technology also called display poor, which used the port. That's very similar looking too.
00:50
Uh hmm. I cable which I'll show you in another slide.
00:56
S o d h d v i D and D V I I connection types. There's a single legged version that's Max Band with 165 megahertz that can push a maximum screen resolution of 1920 by 10. 80
01:10
at 60 hertz or 12 8 by 10. 24 85 hertz
01:15
a duel late doubles the throughput with increased number of pins, eh? So we can have 2040 80 by 15. 36. When you want to start driving an image on a bigger screen, you're gonna need a cable that can support a higher bandwith to push that video.
01:34
RC A cable's an older type of cable been around for a very long time could be used to carry audio or video signals. It's analog.
01:45
It's a composite character that transmits through a single wire
01:49
you can do if you're doing video. It's common to see it as a component video where you have a separate one for the red signal Green signal on Blue Single
01:59
See that and Higher and televisions that used to be component video and B R C. A. If it's the if it's older standard, like in a VCR, it might just be yellow with a red and white. The yellow would be the video, with all the signals already compressed into one,
02:15
and then the red and White would represent the right and left channel, respectively.
02:22
Uh, and one of the most popular ones right now, between home theater TVs and even on
02:27
computers, H. D. M. I. Is the new
02:30
standard standard issue. My cables could be used to go from video card to LCDs and to go from Blue Ray players, two TVs and everything in between. There's also been to other variations, like many A c M I and micro issue my which allows you to take
02:50
video from a
02:51
tablet that has a many a sea, my poor micro
02:55
issue my port and put it into a full sized TV that does have any she might port so kind of you display your tablet on two.
03:02
A bigger screen.
03:07
There's also the mini didn't six connector that was most famous for s video only carried video.
03:14
I was kind of a go between. It was kind of like a slightly increased quality from what you had with standard R c A. For your video.
03:23
And then there's the BNC connectors, another way of doing component video where it broke it out
03:29
into, um the red, green and blue and then had two channels for this sinking those three
03:36
colors.
03:37
03:43
but it was also available for
03:46
video cars and monitors for a short time.
03:50
You don't see it too much anymore.
03:55
S O C. R T connectors always usually use the V g a connector. The 15 pin three row deep connect BB connector. It was analog was blue at the end. Almost always blue.
04:10
It looked like
04:14
this.
04:15
That's the standard VJ Analog
04:17
D B connector
04:21
uh, also known as D shell or diesel marine
04:29
cries The use of analog signal used the Ram Dak random access memory Digital analog because digital coming off computer had to be converted to analog to go out to the Bader go C R T is for analog.
04:39
That conversion happened on the video card itself
04:45
real briefly or is she an example of some of these connectors?
04:49
So here we have a USB cable or issue my cable now to know on this one is this is, um
04:58
this is a team I too many h t m I.
05:00
So you can see this one is bigger. This is your standard issue my cable
05:04
right there
05:06
and then this one
05:09
is smaller
05:11
and this is many. So this is designed to go into a tablet that already has a many interface. Or usually a lot of mobile devices might already have interface for that
05:19
to display. Or sometimes you might see it on a graphics card.
05:24
But
05:25
important thing to note. There's also one smaller than this that we mentioned which is the micro, which looks very similar but even smaller than this. And it could be used to display on more, uh, more commonly from cell phones. Be able to display your video to a TV using H D M I
05:42
or LCD monitor if it hasn't seen my
05:46
This is standard Devi I connector.
05:50
This would go from the back of the graphics card to the vaccine monitor,
05:55
as shown here,
05:59
This one could support to monitor So you could see this plugs in,
06:11
see how those in match up and that and would go
06:14
to the monitor.
06:15
In this case, this video card also has
06:18
the mini HD and my connector right there, which I could use
06:24
this cable for. That I mentioned earlier to display video
06:29
onto a TV with a C M I.
06:35
This one r c a k would look like this one is only audio. This is the red and white. Red is for, uh, red is for the right channel. Why is for the Left Channel? But if it had a yellow one that could do video, that's that's the most common way you'd see would be a yellow, red and white
06:53
for displaying video.
06:56
And that's an example of if we had a devi I on the video card
07:00
and we only had a v g A connector. We could convert the signal by plugging Devi I into one
07:05
an analog and to the other side with a traditional v g a cable.
07:12
It's gonna be duel has, like, a accent in this pins. So that stool right there?
07:17
Yeah. Yeah. So that's a good point.
07:24
Yes. So this cable only has a single, uh, doesn't have the cross on the end. Only has a single
07:31
metal, but I don't have the
07:34
Yeah, that one only has the one
07:36
single horizontal and said the duel and you're missing the minute pins in the very yes
07:43
and then the standard audio connection for 5.1, they'll use the standard connections that you'd use that look like a headphone
07:49
plug
07:50
for each speaker. So we'd have won for the main speaker out, which could also be your ah,
07:57
your front speakers lined out, which would be an unamplified signal out if you're feeding it into another device
08:03
line in through recording in a lot of times line and my microphone, Jax might be shared.
08:11
You might have a reroute, which will let you connect to a surround sound rear speakers,
08:15
um, and then analog or digital out, which will let you do a digital form of the audio, usually over a
08:22
fiber optics cable.
