This question is one of the most common related to computer monitors. There are different resolutions for different types of screens, but the resolution is typically the number of pixels per inch. The refresh rate indicates how many frames per second a monitor can display. Higher resolutions typically need higher refresh rates to avoid any ghosting or blurring.   The resolution of a monitor refers to its width and height in pixels. The higher the resolution, the sharper and clearer images will be on-screen. The refresh rate is measured in Hertz (Hz) and it reflects how quickly a screen refreshes when images are being displayed on it.
