How do I know the screen resolution? Popular ways

The need to understand the question of how to determine the screen resolution can be caused by a variety of reasons. Although with increasing performance of modern video adapters and CPUs, as well as by eliminating a number of "childhood diseases" drivers, many issues related to the resolution disappeared, still in some cases, the ability to determine the number of pixels is useful. You can find out the screen resolution in several ways, each of which gives an accurate result. The difference is only in the usability and preferences of each particular user.

The existing principle of constructing images on displays suggests that the screen consists of a set of pixel points, controlling the brightness / chromaticity of which it is possible to form the desired picture. It does not matter whether the old CRT technology of the device or the modern LCD is used. The video adapter driver allows you to set various standard combinations of the number of points on the vertical and horizontal axes, additionally based on the data received from the monitor. For example, the resolution can be 800x600, 1024x768, 1680x1050, etc. It is not difficult to understand that with an increase in the number of displayed points, the image becomes more detailed. Also, due to the fact that more information is placed on the unit of screen space, it is more convenient to work with a computer. So, if at 800x600 many pages in the global network when viewing need to be rewound with a horizontal slider (without scaling), then 1680x1050 allows to forget about this function.

Standard LCD screen resolution

Unlike CRT displays, where the picture quality did not depend on the resolution, being clear enough, in TFT it's different. Because of the features of the matrix, they always have a "native resolution", in which the quality is the best. It is usually specified in the instruction, 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 determine the screen resolution. The easiest way is to use the built-in operating system mechanism. Since in the different versions of the system the settings window looks individual, we will consider Windows 7 and 8 as the most popular solutions. So, you need to minimize all open windows and click on the free area of the desktop right mouse button. 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.


Each Windows system includes a package of DirectX libraries. 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, open the "Display" tab and see the "Screen Mode" line - this is the current number of points.

How can I find out the screen resolution with a third-party program?

Although this method can not be considered the simplest, it is effective, so we specify it. It is necessary to download and install the AIDA64 program (available free of charge). After launching it, select "Display" and the "Desktop" sub-item. Here is the "Resolution" line.

How can I find out the resolution of the screen through the network?

Very often the task of determining the number of pixels occurs before the webmasters, since, having this data, you can properly optimize the Internet resource. For them (and everyone who wants) on the network, there are many sites that determine the current resolution.
