In general, rendering resolution refers to the total number of pixels per unit area needed to compose an image. The unit of resolution is measured in dpi (points per inch), lpi (lines per inch), ppi (pixels per inch), etc. This is essential to render the image when it looks blurred and spot some squares. One of the primary uses of rendering resolution is that the higher the resolution, the more pixels it contains, thus giving more detailed images on the screen. For example, in most cases, a good resolution requires 720*480 pixels, and if you want to go further, choose 2000*1500 pixels, where 2000 refers to the pixel width, and 1500 refers to the pixel height. Thus, high resolution plays a vital role in rendering good-quality images.
