There are a few things to consider when selecting a device display, from its size and resolution to whether it's a touchscreen. Your device's form, like a laptop or a tablet, can also impact your experience. Learn how these factors affect the look and function of your screen.
Screen size measures how big the display is. It's measured diagonally, with commons sizes of 12 to 15 inches.
A bigger screen will allow you to see more windows and apps at once, though the screen will weigh more than a smaller screen.
Resolution measures how many pixels are on your screen. The more pixels, the sharper your display will be.
Full high-definition, or HD, measures 1920 x 1080 pixels. 4K, sometimes called Ultra HD, measures 3840 x 2160 pixels.
You can interact with touchscreen devices using your fingertips or sometimes a digital pen, which lets you write on your PC like it's a piece of paper.
Besides a standard laptop, consider a tablet for portability or a 2-in-1, which looks like a laptop but can fold into a tablet or spin its screen around.
Compare monitor's view area (VW x VH) with the active area of the touch overlay. It's fine if the touch overlay’s active area is slightly larger than the monitor's view area.
Now compare monitor's outside size (OW x OH) with that of the touch overlay. These dimensions are not critical to the functionality of the touch overlay. They only affects the appearance of the touch display.
