Monitor resolution is measured by the number of pixels displayed horizontally and vertically, with higher resolutions displaying more pixels and crisper images. The sharpness of images depends on the resolution and screen size, with smaller screens displaying sharper images at lower resolutions. As resolution increases, more pixels can be displayed per inch, allowing for smaller text and images. Common higher resolutions include 1280x800, 1920x1080, and higher, while recommended resolutions vary depending on screen size. Printer resolution is also measured in dots per inch (DPI), with higher DPI printers able to place more ink dots in a square inch for sharper printed images.
