How to View or Change the Screen Resolution of a Monitor?

The images you see on your computer screen are made up of "pixels," millions of minimal components. These pixels produce the colors, patterns, and videos you see on your monitor. The number of pixels in a grid, both horizontally and vertically counted, is used to determine the resolution of these pixels. With more pixels in the grid, your resolution becomes clearer or of higher quality.

For many computer-related activities, especially those requiring fine detail, screen resolution is crucial. For instance, when editing images, even the smallest changes are necessary. The screen will need to be adjusted to adequately display intricate details that only the most advanced screen resolution can offer, such as changing a line here or a color there.
