Now we will try to figure out how to increase the screen resolution, what is this concept, how it is defined in televisions familiar to us and on personal computers.
What is called screen resolution?
Display resolution is the most important characteristic of any digital device, indicating the pixel density per unit screen area. In order to learn how to adjust the screen resolution, you first need to figure out what is behind this concept, so let's start with the theory. Any image on a digital medium consists of pixels. They can be noticeable when you look closely at the TV screen, telephone and other equipment. It is small bulbs - pixels - that make up the image so that it looks holistic, not grainy or fragmented. The pixels on the device also have individual characteristics, for example, intensity and color.
The television signal is divided into lines. There are standard line volumes for each digital system, for example, NTSC transmits 525 lines. It should be borne in mind that certain lines work exclusively for transmission of overhead signals.
Basic TV screen resolutions
- The first standard resolution is 720p. It has a frame rate of 50 to 60 Hertz, progressive scan and aspect ratio 16: 9.
- 720p is followed by 1080i. This resolution is interlaced. 1920 x 1080 pixels, also has a framing frequency of 50 to 60, which allows a screen with this resolution to display from 25 to 30 frames per second.
- And the last - 1080r. This resolution has a pixel density of 1920 x 1080, line-by-line scanning and a 16: 9 aspect ratio with a frame frequency of up to 60 Hz.
Standard Resolution for PC and Laptop Monitors
- Typically, a 19-inch screen has a pixel ratio of 1280 x 1024.
- 20-inch screen - 1600 x 1200 pixels.
- The 22-inch screen is already considered widescreen, as it has a resolution of 1680 x 1050 pixels.
- The 24-inch screen is also considered widescreen.
How to increase screen resolution on a computer
To change the resolution in Windows, first go to the "Screen Resolution" section. To do this, you need to click on the "Start" button, then select the "Control Panel" cell, by going to the "Appearance and Personalization" section, activate the configuration command. If you are interested in screen resolution in Windows 7, then the above step will suit you. On other systems, the algorithm may change slightly. However, we go further. The second configuration step is directly selecting the desired resolution and saving the set parameters. An important note to owners of computers who are wondering how to increase the screen resolution in Windows: after setting the screen resolution, the monitor goes blank for a few seconds. It is also worth noting that the applied changes remain the same for all PC users.
Approximately the same manipulations are performed to increase the resolution on other electronic devices. For example, setting the resolution increase for a webcam. All Skype users strive to have the best connection during negotiations. Therefore, the quality of the image transmitted by the webcam is very important. To get started, open your camera’s settings menu. It must be installed with the drivers of the electronic device. In the settings section, select the necessary camera parameters and save them.
Best Practices for Choosing the Best Resolution TV
Often, customers choose the TV with the lowest resolution in order to eliminate the risk of interference and all kinds of network errors, because they believe that a small resolution is more resistant to damage. In fact, such a judgment is erroneous. Problems with the television network may arise if, for example, the performance of the technical part does not match the resolution of the matrix. The reason for the low image quality is most often the internal functional complex of signal processing settings. So we discussed the question of how to increase the screen resolution, and described the essence of this concept for various devices.
