The need to deal with the question of how to find out the screen resolution can be caused by a variety of reasons. Although with the increase in performance of modern video adapters and central processors, and also due to the elimination of a number of “childhood diseases” of drivers, many questions regarding resolution have disappeared, nevertheless, in some cases, the ability to determine the number of pixels will come in handy.
You can find out the screen resolution in several ways, each of which gives an accurate result. The only difference is the usability and preferences of each individual user.
About permissions
The existing principle of constructing an image on displays suggests that the screen consists of many pixel dots, controlling the brightness / color of which you can form the desired image. It does not matter if the device is using outdated CRT technology or a modern LCD. The video adapter driver allows you to set various standard combinations of the number of points along the vertical and horizontal axes, additionally based on data received from the monitor. For example, the resolution can be 800x600, 1024x768, 1680x1050, etc. It is easy to understand that as the number of displayed points increases, the image becomes more detailed.
Also, due to the fact that there is more graphic information per unit area of ​​the screen, it is more convenient to work with a computer. So, if at 800x600 many pages on the global network need to be rewound with a horizontal slider when viewing (without scaling), then 1680x1050 allows you to forget about this function.
Standard LCD Screen Resolution
Unlike CRT displays, in which the picture quality did not depend on resolution, being quite clear, in TFT everything is different. Due to the characteristics of the matrix, they always have a “native resolution” in which the quality is the best. Usually it is indicated in the instructions, and is also automatically determined by modern operating systems. It is recommended to work in this resolution.
From theory to practice
So, let's figure out how to find out the screen resolution. The easiest way is to use the built-in mechanism of the operating system. Since the settings window looks different in different versions of the system, we will consider Windows 7 and 8 as the most popular solutions. So, you need to minimize all open windows and press the right mouse button on a free area of ​​the desktop. In the menu that appears, select “Screen Resolution”. In the displayed window, you can see the item "Resolution", where the current one is indicated. By clicking the drop-down menu opposite, the user can select any other one available.
Diagnostics
Each Windows system includes a DirectX library package. One of the modules is informational. To use it, you need to select "Run" in the menu of the "Start" button, type dxdiag and press Enter. In the window that appears, you need to open the “Screen” tab and see the line “Screen mode” - this is the current number of points.
How to find out the screen resolution using a third-party program?
Although this method cannot be considered the simplest, it is effective, so we indicate it. You need to download and install the AIDA64 program (available as a free option). After its launch, select “Display” and the sub-item “Desktop”. There is a line "Permission".
How to find screen resolution over the network?
Very often, the task of determining the number of pixels arises before webmasters, since, having this data, you can properly optimize the Internet resource. For them (and everyone), there are many sites on the network that determine the current resolution.
