In a display specified as 600x400 the number of pixels across the display screen is? A. 600 B. 400 C. 240000 D. All of these
when a digital image is displayed on the computer screen, its size is determined by three factors: 1) screen's resolution setting 2) the screen's size 3) the number of pixels in the image. a monitor may be specified as being a low-resolution 640 x 480, a medium resolution of 800 x 600, or a high-resolution of 1024 x 768 or more. note: the first number in the pair is the number of pixels across the screen. the second number is the number of rows of pixels down the screen. ∴ the total number of pixels in a display screen is a multiplication of the two numbers. the given display is specified as 600 × 400. ∴ the total number of pixels across the display will be: n = 600 × 400 = 240000
