In the old days of technology, screen resolution (also called display resolution) was not much of an issue. Windows came with a few preset options and to get higher resolution or more colors (or both) you would install a driver for your video card. As time went on, you could choose better video cards and better monitors as well. Today we have lots of options when it comes to displays, their quality, and the supported resolutions. In this article, we take you through a bit of history and explain all the essential concepts, including common acronyms for screen resolutions, like 1080p or 4K.
