Choose fitting resolution for your LED display screen to present perfect artwork

Here is a picture I made for you to understand the difference between fitting resolution and unfitting resolution on the same LED display. Usually as a graphic designer, you probably expect to present your artwork at perfect resolution, 4K, Full HD, HD or 480P and etc. So for the LED display / screen you would like to buy, its physical resolution is supposed to fit better with the images and videos you design.
