Resolution refers to the number of pixels on a screen. High resolution means more pixels and generally more space and detail, while low resolution means fewer pixels, and often less space. If you are using a typical (not high-end) laptop or an old screen, you likely have a low resolution. The image below shows the difference in real estate between common resolutions.

Since each part of the photo has different brightness, there will be a contrast between light and dark. Contrast refers to the degree of contrast between light and dark in the photo. The higher the contrast, the greater the contrast between light and dark, the clearer the graphics, the more vivid the colors, and the stronger the layering of the photo; the lower the contrast, the smaller the contrast between light and dark, and the picture will appear gray. Increasing the contrast can make the layers of the photo more distinct. It is a common method when processing photos of humanities, architecture, and landscapes. The general IPS contrast ratio can only reach the standard of 900~1000:1, but after long-term optimization, the contrast ratio of the ingnok display has reached an astonishing 1200:1.
