How Does A Single Cable Control Every Pixel On An Entire TV Screen?

Televisions have wireless connections too, but they have not been fully introduced in the market. Most televisions are connected using a cable. This cable provides electricity to the TV and helps run other functions of the TV such as the speakers.

How does a single cable control every pixel on a TV screen?


First, let us talk about what type of cable is used. The cable used in connecting the television is called an HDMI cable. Tv used in recent times has an HDMI port in them when they are manufactured in the factory. These ports allow the connection of these cables so that the tv and other components can communicate effectively. The HDMI cable and the HDMI port are of the same size worldwide. It means that you will be able to use the TV’s HDMI cable for connecting to another TV with an HDMI connection. These cables are also used in connecting external devices to the tv. Some of these external devices may be a DVD, gaming console, or an internet modem.

When we look at the cable externally, we see one thick cable. But when we cut the cable in half, we can see 19 different cables. You do not need to cut your cable to see the number of cables physically. If you look at the HDMI cable opening, you will see that there are 19 pins inside it. Each pin is for a separate wire, and each wire and pin have different functions. Some pins may carry out the same function, but the cable manufacturing might have added extra pins to carry out the same function on different pins. This is because if one of the pins does not work, the other pin will carry out the task.

These pins may vary as not all televisions need to have the same number of pixels.  I will explain this using an example so that you can understand it fully. Suppose there are two TVs. One has a 1000 megapixels display, and the other has a 2000 megapixels display. Who do you think would require an HDMI cable with more pins? The one with the more megapixels, of course.

However, televisions are not connected using HDMI cables only. Some TVs are old and use the older technology, which is called USB. The USB cables only have five wires and pins. It does not affect the number of pixels displayed on the screen, but it affects pixel quality. As a rule, you must have seen TVs with HDMI cables giving better video quality than TVs with a USB connection.

Moreover, TVs with the latest technology have HDMI cables with only four pins and four wires. These cables give much better quality and are cheaper than other cables. When manufacturing these cables, the companies have two ways to deliver energy to the pixel. One way was to use the same amount of cables for the number of pixels the TV displayed. That was, however, not possible due to an obvious reason. The reason was that it is not possible to attach the same number of pixels to a tv.

I will explain this using an example so that you can understand fully about the concept. Suppose a tv produces 4000 megapixels, and it needs the energy to run those pixels. You will have to attach four thousand wires to the tv to make it run. It is not possible as it would be expensive and no one would ever buy a tv. Moreover, if the display is sandy, it would be difficult and time-consuming to find the wires’ error.

Due to the above reasons, tv manufacturing companies went for the second option. The second option was that they would use one cable that had multiple small cables inside it. These cables would not be of the same number of pixels. If this happened, the cable would be huge. As a result, the tv manufacturers decided that they would use lesser cables. There would be one modification to these cables.

Each cable would be able to provide more energy than usual. It means that one small cable inside the mega cable would power more than one pixel. This way they would be able to use lesser cables and would have lesser cost. Moreover, if any fault would arise, they would identify it or change the whole cable. However, they had to take care of one thing: they needed to have higher quality cables for higher speeds.

So most of you might be wondering how one cable will assist the delivery of energy for so many pixels. That depends on the speed the cable is having. If it has a higher speed, the cable will be able to provide energy to pixels, and if the cable can support lesser speeds, it will be able to assist fewer pixels. If we use high-speed cables, the number of cables will be less, but the number of cables will be more if we use lower speeds. That is the reason why the latest wires only have four electric wires in them. These wires are less in number, but they can support very high speeds, so fewer wires are needed.

I will explain all of this using an example so that you have a better understanding of what I want you to understand. If there are 2 million pixels that need to be provided energy to, you have two options. One is to connect 2 million cables to the tv, and the other is to connect fewer cables that can send power to the pixels. The fewer cables would have so much speed that they will provide energy to pixels at the same time if we used 2 million wires instead. As a result, you will need wires with a speed of 120 MHz, Which is 60MHz x 2. It means that the pixel will remain for a fraction of a second.

Have you ever wondered how the pixel can change its color? Most of you might think that there are millions of lights inside each pixel. This theory was believed by people before, but it has been proven wrong by scientists. Each pixel is made up of only 3 colors. Those three colors are red, green and blue. You must have heard about the words RGB. RGB stands for red, green, and blue. Most of you might be wondering how does the pixel display other colors such as orange and purple.

These pixels mix in different proportions to display any color. These three colors can be used to make any color you want. When you want to display an orange color, the pixel will automatically mix red and green. This shifting of colors is done on a very small scale, and the human eyes cannot identify it. A single cable manages it in the main cable. All the cable wires communicate with each other to fix the color ratio and display the required colors. This process is so quick that the human eye cannot identify it.

Moreover, there are newer cables in the market, and these cables are called optic fibers. From fibers, you can catch the idea that they are thin shreds. Optical fiber is a long cable, and it has millions of thin wires. These wires are as small as hair and are carefully cut. They are made up of glass. The glass allows the reflection of signals internally, and as a result, transmission speeds are higher than cables that use copper as their medium of transmission.

Most TVs are connected using fiber optic cables, and this is the latest technology use by TVs. This technology is also used in internet connections for higher speeds. As there are millions of thin shreds of glass in the wire, they can carry out multiple functions. I will explain this using an example so that you have a better understanding of what I am talking about. Suppose there is a led tv and it has millions of pixels. There would be no need to put millions of wires into the tv to provide energy to all pixels. There are millions of glass wires that deliver the signals and power to these pixels.

Moreover, these signals would reach a much faster rate. The quality of the display depends on the amount of energy received by the pixels. The energy is more, the pixels would produce a better picture, and if the power delivered to the pixels is low, the picture quality would not be as good.

How to increase the pixel quality of a screen using a single wire?

Download Gigapixel AI:


Yes, it’s true. You can increase the quality of your pixels by using these after-market apps. Most of the time, you must be suffering from bad quality of pictures. Do you know the reason behind this? The reason is that over time the cables are worn out and do not give the same performance as before. So you have two options. The first option is that you have to change all your previous wires. It might cost you a lot of money as these cables may be expensive. If you are using fiber optic cables, you won’t face this issue, but if you do, you might have to change them too, and they can be costly.

As a result, you will have to move on to the next option. The other option is to use after-market apps such as gigapixel AI. Most people say that this app cleans up the software that controls all the processing of signals to the pixels, but that is not true. This software has one function, and that function is to increase the power input from the source. It tricks the tv into pulling more power from the sockets. Most of the time, when these wires become old, they cannot transfer energy to the pixels at a high rate. So, these apps pull out power from the source and promote higher power to the pixels. The more power provided to the pixels, the higher the quality, and the lesser energy provided to the pixels, the lower the picture quality.

Resize your screen:


Yes, you may also improve picture quality by resizing your screen. Most of you might be wondering what the picture’s resizing has to do with the video quality. When you reduce the size of the video, the pixels come together. Once the pixels come to tolerate, the gap between them decreases, and you will not be able to see that rough video again. The distorted video is due to the spaces between the pixels. Once spaces are removed, the picture quality increases, and you get a much sharper video quality.

Disadvantages of using one cable for controlling pixels:


Although there are many advantages of using one cable for pixels, there are many disadvantages too. One of the cons is that if one wire is used, all the pixels would be dependent on one cable. It is not a good thing. I will explain this using an example so that you can understand what I am trying to say. If we have an led tv, it has 5 million pixels that display a larger pixel. Of all of the 5 million pixels are connected using one cable. If there is a fault that cable, all the energy connections to those pixels will be affected. The picture quality will become sandy, and in worst cases, the screen may become pitch black.

If one cable is used for all the pixels, the speed might be affected as there is not one pixel but millions of pixels. Some people may argue that one pixel uses very little energy, and how is it possible that the speed may be affected. These people should understand that if one pixel’s energy is multiplied by millions, the overall energy is very high. If transmission becomes slow, you might see an unclear video, or the video playing on the screen will not be smooth. It will glitch a lot.

Advantages of using one cable for controlling pixels:


There are many advantages of using one cable for controlling cables, and one of those advantages is that there is no voltage drop when we use one wire. When only one wire is connected, all the energy and voltage are delivered to the pixels. If we use multiple connections, there would be more wires involved in the delivery, and their wires will have some resistance. The more the connections, the more resistance will be. The more the resistance, the more the voltage drop. When we use a single wire, the resistance is lesser, and there is a smaller voltage drop. As a result, more power supply to pixels means that the picture quality would be better.

Another advantage of using one cable for controlling pixels is that error identification becomes bearable. If we use many wires, we would have to check those wires manually and see which wire has an error. Most of the time, huge TVs use multiple cables, and error identification becomes very difficult. Some might argue we will face a disadvantage if an error arises. You will have to change the whole wire. It is true. But the time saved using changing the wire is much more valuable than the price of the wire itself.

Moreover, if we use a single cable, we would not waste any energy if the pixel is not working. If multiple cables are used and a section of pixels stops working, the wires would continue to give power to those pixels that are not working, and as a result, energy is wasted. If we use a single cable, an error in the pixel will stop all the processes. As a result, we will quickly change the wire and stop the energy from being wasted.



From the above data, we can conclude that it is not a single viable that controls every pixel on the screen. There are many smaller cables inside the cable that controls different functions of the pixel.
