In today's world, everything is changing rapidly. Cameras of all models, from the cheapest “soap dishes” to professional “DSLRs”, are able to shoot HD quality videos. This video is also possible for expensive models of mobile phones. DVD video standards are a thing of the past.
Film studios make new spectacular films with previously inaccessible effects. The requirements for video and television equipment standards are also growing. Viewers need films shot in a better image - they want to watch them on wide screens, and not just on a computer monitor.
What is a TV screen resolution of 1920x1080
Screen resolution is called that which affects the clarity of the image. This is the quality of pictures and text messages. The unit of resolution is a pixel. Pixels are responsible for the formation of the image on the screen. Today, when buying a TV with a plasma or LCD screen, you will probably come across the term Full HD - 1920x1080, which the seller will tell you about.
These televisions are now in every major store, they are affordable, it is they who are now looking for buyers. If you answer that you do not know this term, the seller will add that this sign is the best recommendation for a TV, and the resolution of 1920x1080 is an indicator of high image quality.
How to choose a TV
When you make a TV selection, pay attention to the size of the screen. Screens are measured in inches. One inch is about two and a half centimeters. But monitors with a large screen are demanding on a graphics card. That is, if you have an old computer, and you bought a modern monitor twenty-four inches diagonally, then expect your iron horse to slow down slightly.
Budget monitors 18-19 inches are good only at their price. And for those who love battle scenes on the big screen, monitors with 27 inches diagonal are suitable.
Some people are wondering why modern monitors are so narrow and elongated. There is an explanation for this. For modern films, there are filming format standards. They are filmed such, with an elongated and narrow image. If you watch a new movie or play a modern game on an old square-shaped monitor, the picture will be small, and not everyone will like it.
FullHD or HD Ready
On the packaging boxes of TVs, in addition to FullHD labels, other labels are often found - HD Ready.
What is the difference?
The European Association of Telecommunications Technology and Information Systems in 2005 adopted standards for new TV models that will display high quality video. They fall into two categories: HD Ready and FullHD.
HD Ready supports the minimum resolution for this class - 720 lines, and FullHD, where the screen resolution is 1920x1080, able to handle video with 1080 lines.
This name was picked up by the Japanese company Sony, when in 2007 it named the FullHD brand a number of its products. Other companies in this market segment also began to name their products.
Therefore, the majority of FullHD liquid crystal and plasma television receivers sold in our time (translated from English as “full screen resolution 1920x1080”) have an aspect ratio of 16 by 9 and support video with 1080 lines of images. Such images are advantageously different in quality from a simple DVD. they are clearer and better.
So what is screen resolution, how do screen settings affect the image that we see on the monitor?
A television screen, whatever it may be, plasma or liquid crystal, is a matrix that consists of pixels located horizontally and vertically on the screen. Their number is called the resolution of the matrix. Screen resolution is of many types, but the most famous are 1024x768, 1366x768 and many others.
Types of television signals
The highest resolution now is Full HD - 1920x1080.
Television signals also have a resolution that has not yet come to a common standard throughout the world. In the United States, for example, an analog type signal is called NTSC (with a resolution of 640 by 480 pixels). In European countries, they use PAL signals and SECAM signals with a resolution of 720 by 576 pixels.
The signal may also differ in frame rate: fifty or sixty hertz.
In every modern TV, there is a processor that converts the incoming signals to the standard to which the TV matrix conforms. If the incoming signal and the matrix were with the same standard pixel resolution, then the image would immediately be clear and high-quality. But, since the signal standards are different in types, parameters and matrices, the TV must independently convert the signal to show a clear image.
Progressive and Interlaced
The range in which the TV channels broadcast is small. There is not enough space for everyone. The image transmitted by the channel can be formed in two ways. Progressive, displaying all frames in full (where the lines - even and odd - go one after another), and interlaced.
To save space on the air, a scan was invented that halves the frame rate. She was called interlaced. First, in the odd lines the first half of the frame is transmitted, then in the even lines the second half. Interlacing would look blurry if an action were not invented to restore image quality.
In order to explain the method that forms the image, after the number of lines the initial English is written: “p” or “i”. For example: the resolution of 1920 x 1080p indicates that the picture was formed in a progressive way. And the 720i marking will indicate that there are 720 lines in the video. And the letter i stands for the interlaced method - interlaced. In order to indicate the format, indicate the size of the frame per second. When they write 1080p30, it means that in this video there are thirty frames running in a second. The larger the number of frames, the better and more detailed the picture looks.
Full HD Requirements
Televisions of the latest generations display images of both types of scans. Thus, a screen resolution of 1920x1080 and a 16: 9 aspect ratio should be present on a Full HD TV. These are standard requirements for this type of display of the incoming video signal.
Therefore, a resolution of 1920x1080 will mean that the TV has 1920 horizontal dots and 1080 vertical. Such TVs will catch the highest quality signals accepted in the world (HDTV standards).
Tricolor TV, a commercial TV operator, has been offering a package since 2012 that includes twenty-five HD-quality channels. Once upon a time, such channels may be free for everyone.
If you have problems with the monitor, a fuzzy font or image, you need to understand that this changes due to the size of the resolution. Say, when a large resolution is set, for example, 1920x1080, then the objects will be clear. And on the monitor they will fit a larger number. And with a low resolution, say 800 by 600, the monitor will fit smaller objects, but they will look larger.
But this does not mean that you can set the screen resolution you like to 1920x1080. It may not be supported by your monitor or TV model. CRT monitors support a resolution of 1024 by 768 pixels or 800 by 600 and are suitable for all types. LCD monitors and laptop screens support high resolution. And they work with the look that is suitable only for their model.
A large monitor corresponds to the same high resolution. With it, clarity is increased and the image size is reduced.
How to adjust monitor resolution in Windows 7
To do this, go to the "Start" menu, then go up to the "Control Panel" and then go to "Appearance" and "Personalization". Then - in the "Resolution Setting" of the monitor. Now open the list near the inscription "Resolution", use the slider to set the resolution you need, then click the "Apply screen settings" button.
At the end, click "Save Screen Resolution Settings."
Later models of monitors, on liquid crystals, work with their own resolution. It does not need to be configured - it is already recommended for this type. Such monitors are divided into two types: with a wide screen and a ratio of 16: 9 and 16:10 and standard with a ratio of 4: 3. If we compare them, then the widescreen has a large width and horizontal resolution.
If you do not know the resolution of the monitor, then it will be recognized from the directory, on the manufacturer’s website or by EDID.
What is EDID?
There is a data standard that contains information about the monitor and its parameters, where it was produced, its resolution, size, color quality characteristics and so on.
If you can’t find out by EDID, then how to make the screen resolution
What to do if when connecting a television receiver with a large screen, the image does not fit and looks cut off at the edges? To solve the problem, you need to update the video card drivers of your computer. After that, specify in your computer setup your model as a base, or primary monitor. Then you need to make sure that the TV is connected to the computer with a digital connection, and also that there are no restrictions on it.
Install the Moninfo EDID program (it is available on the Internet). After that, check the resolution of your TV in it. If it is supported, that’s good. If not, then you have to edit the EDID and set the resolution yourself.
If the image does not fit
To deal with this problem, you need to turn off the Overscan option in the television receiver.
If this is a computer, then after a mandatory update of the graphics card drivers, right-click on the desktop. If you have a GeForce graphics card, then go to the NVIDIA program settings. If you have a Radeon graphics card, then go to the Catalyst Control Center program. Then adjust the settings with the slider in the “desktop” settings to the desired value.
How to adjust resolution
First you need to disable EDID.
Then set the resolution to 1920x1080 in the screen properties.
Reinstall the video card driver (remove the old driver).
If the previous steps did not help, try reinstalling the Windows system.
Hopefully, after this information, questions about how to set a screen resolution of 1920x1080 will be easier to solve.
