How is resolution measured?

• A. Horizontal x vertical pixels displayed
• B. Total number of colors
• C. Brightness level
• D. Refresh rate

Answer: (A)

Resolution is measured by how many pixels make up the display in each dimension, usually written as width by height. This expresses the amount of detail the screen can show; more pixels across and down means a crisper image. For example, a 1920x1080 screen has 1920 pixels across and 1080 pixels down, giving about 2.07 million pixels in total. Other options describe different specs: the total number of colors refers to color depth, not resolution; brightness level is about how bright the image appears; and the refresh rate is how many times per second the image is updated. So, resolution specifically refers to horizontal by vertical pixels displayed.
