The main difference between a laptop with a regular display and a high-resolution display is in the amount of detail and clarity of the visuals presented on the screen. A laptop with a regular display typically offers a lower pixel density and may not be able to display fine details or vivid colors as clearly as a laptop with a high-resolution display. With a high-resolution display, you can expect to see sharper images, more vibrant colors, and a greater level of detail in your visuals.
