This is less than 7.4 video cables, video cables and connectors. Let's get started.
Okay. In this lesson, we're gonna discuss the various and common video connectors and cabling we're gonna go through V g et h d Am I going to talk about the display port and as well as Devi I So let's go and get started.
So v g a video graphics array The V G A connector has been around for years. We have been using that one since the early David Peces on There was connectors, actually, even earlier than that. V g. A. Has been around on the laptops, two desktops, and that at one point was the standard.
that standard has been changed because newer technologies have come forward and we're now used in a D v i N H demise and the display ports. But V G A was the longtime champion of the common video type connector, so V. G. A is an analog interface. The connection between the PC on the monitor
and it was widely used, of course. Like I said, before the newer technologies,
it was introduced way back in 19 ending seven by IBM and it was ah, ps two of interface replace previous digital versions of the C G A e g a. Interfaces, and those had lower resolutions and lower colors.
V g A is a 15 pain come connector traditionally color blue. However, you may see that in other colors as well. Sometimes you can almost mistake it for a serial port. But, however, but the 15 peons are three rows of five PM so therefore, it kind of
gives you the little indication that's a PGA versus a serial port
on the proper connector name for V. G. A. Is actually the D E 15
new LCD monitors may include the V G A. Ports for legacy PCs and a lot of PCs may have the V G, a port for legacy monitors. So even though you're starting to see the new Devi I in the display ports, you're still common to see the V G. A. Because it was so widely used.
Then there's a distance limitation of 10 meters. After that, fuzziness and distortion will be again toe happen with this connector.
Now, as we step up forward in time, now we're to the new HD. Am I the high definition multimedia interface.
Um, the aged am I high definition multimedia interfaces Now the standard video interfaces on devices today, digital signal that can carries both audio and video. So this is an improvement of the previous V G A, which just carried video.
This is a 19 PM proprietary connection to this type of connection, has a type A connector and has a distance limitation of up to 20 meters. And it can handle many, many video resolutions.
The standard video connection in many devices on the market today, and smaller devices used the mini HD Am I,
which is a type C connector and even images below. You'll see that the standard HD my port as well as the aged in my cables and I was on the far right. You'll see the mini HTM. I now am I again is starting to be the standard in for video connections on laptops, desktops
and other equipment as well.
H. D M. I is the new standard off across a lot of digital devices.
Next we move to the display port. Now the display poured is a standard created by the Video Electronic Standards Association, or Visa V. E s. A
data sent over a display. Poor connections eyes in the form of very similar to information over Annette Ethernet network. It's like a packet ties, information or data that it's being sit.
It's compatible with H. D M I S O. Therefore, you can use a passive adapter between the two. It doesn't have to be a power connector or power adapter.
It's a you type connector on. There's two type of connectors. There's a standard connector and a smaller many display port as well. And you're beginning cities a lot on the PCs and desktops on the new display port.
And then we have the Devi I digital visual interface. Devi I is a video display interface developed by the Digital Display Work Group, or D D WG, the center faces designed to transmit un compressed digital video and could be configured to support multi molds
of such as Devi I A, which is an along on Lee.
There's a D V i. D. Which is digital on Lee or Devi I I, which is digital and analog. So just like H d M. I. It could do the video and the audio.
So Davey i d and e v I I connectors come in two varieties. There's a single leak in a duel link. Now the single link on the D. V I. The maximum bandwidth capacity is 165 165 megahertz. The maximum regular resolution is 19 by 2019 20 by 10 80
at 60 Hertz. Then you have 12. 80 by 10. 24 at 85 hurts. So did two different modes there on the single link. Now on the dual lake, we have displays capable of 2048 by 15 36. And that's that 6 60 hertz.
So a lot of ah capability there with the Devi I interface and that standard
and on the right, you'll see the different Devi I ports. At the top is the Devi. I mean, that's the single link the D V I. I. Then you have a DVD. I do link and you can see the difference between the two. That's one has more pins in the middle of it. Then you have the d v i. D. Which is the single league.
Then you have the d v i. D. Dual link again. More peons there in the center of that,
then you have the D v ay, ay, ay which is the analog on Lee. So different devi i ports and connectors for different uses.
OK, so that's our step through for today. We've kinda went through and step through the V g et the HD my as well as the middIe aged. Am I? We talked about the display port, the D V I. D V I D D v i I. And we also discussed the Devi Aye ayes and the other forms of Devi I. So
that's it for today's lesson and we will see you in the next lesson.
