What does the «screen resolution» actually mean? 4K, HD and Co.

Abbreviations such as Full HD, 4K or WQHD always mean screen resolutions, which differ in the format and pixel number. The following article Explains what screen resolution is, which formats and standard There are and where they are used.

1. What does screen resolution mean?

The term «screen resolution» describes a value in the pixels capable of producing a display, for example on the mobile phone or a PC via its graphic card connection. The value resolution of the value is generally reported in the specific Number of horizontal pixels X Vertical pixels number Given, for example 1920 × 1080 (Full HD). This information about a monitor means that this The resolution of 1920 pixels in width and 1080 pixels can represent in height. If the values ​​multiply, you arrive at the maximum number of Pixels, in the case of this example 2,073,600. A display with a screen resolution of 2560 × 1440 pixels (WQHD) has a total number of pixels of 3,686,400 pixels.

2. The most important screen resolutions in an overview

The different resolutions of the screen are defined as graphic standards by the Video Electronics Standards Association (VESA) and include very old PC formats such as CGA (320 × 200), VGA (640 × 480) or Svga (800 × 600), current formats such as UHD UH «4K» (3840 × 2160) and Fuhd or «8K» with 7680 × 4320 Pixel.

3. What are the common side conditions?

THE The relationship between the number of horizontal and vertical pixels is also defined as a proportion or (view proportions) And it has an impact on the height and width of the image as a whole. This table reveals which areas of application offer their respective collateral conditions:

The monitors of old pipes with 17 inches, for example, have a screen resolution of 1024 × 768 or 1280 × 1024 and therefore a ratio of 4: 3 and 5: 4. Today the appearance ratio 16: 9 Applied and established for the typical display of large images for monitor and laptop. High quality televisions also have it 21: 9 format and therefore reaches a 2.35: 1 ratio, ideal for filmswhich are also played in this proportion. The material of the film in 16: 9 format on a 21: 9 display makes bad beams appear on the left and right edge. In the desktop area, the 21: 9 format is quite unusual.

4. Your browser knows the screen resolution

Since the Windows 10 operating system also reports web browsers common to screen resolution and the aspect ratio, the websites can read this information for choosing the display and positioning of advertisements or viewing the screen resolution in the browser.

The screen resolution in Windows 10 is managed in the settings under the system. Here you can Regulate the resolution for connected screens and their alignment.

Two screens: If you have more than one display, you will find more information on the setting and configuration in our suggestion «Sets two screens in Windows 10». Just click on the connection.

It is not necessary to find out which resolution supports the monitor, since the display data channel (DDC) for DVI and HDMI, as well as similar techniques for the display doors show the display independently, that the resolutions support. Windows always suggests the native resolution in which the connected display should be managed for the best image display.

6. Solter resolution only native only

The resolution and therefore the number of pixels describe only the number and the ratio, But not the real area on which pixels are displayed. For example, there are WQHD display with a size from 27 to 34 inches, although everyone allowed a resolution of 2560 × 1440 pixels. The different dimensions of the display with the same resolution in turn are in icons, texts and other elements of the operating system on a smaller display are also significantly smallerfrom the density of the pixels, indicated in the number of Pixel for thumb (DPI) It is higher for smaller display.

The number of pixels that the display can view the maximum is indicated as a native resolution. Only in this resolution is the razor of the image. If the resolution is lowered, the smaller pixel image is interpolated, calculated and therefore blurred. So always manage the display in native resolution, which is also recommended by Windows.

If the elements such as writings or icons are too small for you in this resolution, you can in Windows 10 settings below System -> Display Increases the downsizing of the elements.

If, for example, it changes the specifications from 100% to 125%, icons, texts and other elements in Windows are shown larger without changing the resolution itself.

However, the changed downsizing can take to vagus in various apps. In this case, it is possible to run the downsizing of Windows apps through «Extended reduction settings» to avoid the blurred display. It works in some, but not in all cases.
