There are many screen resolutions like 640×480, 800×500, 800×600, 1024×640, 1024×768, 1152×720, 1200×800 and generally the Mac OS computers and laptops comes with 1200 x 800 pixels screen which shows the best display, but there are still loads of computer users who are into the previous world, and use Windows with smaller resolutions.
