What is my screen resolution?

The monitors you attach to your computer and laptop screens have display resolutions in pixels. Each pixel represents a dot on the screen, and the horizontal and vertical pixels make up the screen resolutions. This online tool uses javascript to display your monitor's screen size and browser window size in pixels.

This tool works on any device that supports javascript on their browser. The monitors and laptop screens do not always use maximum resolutions, so you can increase the resolution if your display device supports higher resolutions. On Windows 10, you can change screen resolution by following Change desktop icon size or screen resolution page on Microsoft. On Mac, you can change screen resolution by following Apple page.


Display Resolutions

The display industry has advanced dramatically over the years, and monitors with 2K, 4K, and 8K resolutions are not uncommon these days. In the late 90s and early 2000s, the 1024 x 768 was the most common resolution used. Today, the most commonly used display resolution is 1920 x 1080. The ratio between the horizontal and vertical has changed from 4:3 to 16:9, and the 16:9 aspect ratio is the new normal used on most monitors today.

The following display standards have evolved into the current resolutions.

There are so many variations of horizontal and vertical displays, and the name and standard overlaps with minor pixel differences. We generally use 2K with a monitor having roughly 2,000 horizontal pixels, 3K with 3,000 pixels, 5K with 5,000 pixels and so on.
