Pixel chaos: Different resolutions explained

Not only the screen size, which is usually specified in inches, is crucial, but also the corresponding resolution. Nowadays, we distinguish between four different resolutions, whereby the HD resolution is moving further and further into the past. The resolution tells us how many pixels the displayed image consists of. Generally, the higher the number of pixels, the more detailed the image.


HD resolution, also called High Definition, is a resolution of 1280 x 720 with a format of 16:9. This resolution is now outdated because it looks very pixelated. Even for monitors with a small inch size, you should make sure that the resolution is at least Full HD.

Full HD

FHD resolution, also known as Full HD, is a resolution of 1920 x 1080 with a 16:9 format. FHD is the standard for most monitors and is the most common. This resolution is also completely sufficient for most everyday activities on the PC.


The QHD resolution is an intermediate stage between Full HD and a 4K resolution. Accordingly, QHD has a resolution of 2560 x 1440 with an extended 16:9 format. QHD is also used to express a 2K resolution. The term WQHD expresses the same resolution, but the W (for wide) emphasizes that it is a wide resolution. This resolution is particularly suitable for office work, since several windows fit comfortably next to each other, but also for gaming. Especially with ultrawide monitors, other resolutions occur due to the inch size and a deviating format, which are not explained in more detail here.


The 4K resolution, also called UHD, is the next higher level for monitors. What is already a common resolution in many living rooms is gradually finding its way onto desktops at home. This is a resolution of 3840 x 2160 with a format of 16:9. However, a 4K resolution on a monitor also requires a corresponding graphics card and other hardware so that this resolution also runs smoothly and without problems.
