Determine the required amount of video memory for graphics mode with a resolution of 1920 × 1080

Determine the required amount of video memory for graphics mode with a resolution of 1920 × 1080 pixels and 32-bit color depth.

First, you need to determine the number of points that are located on the screen:

1920 x 1080 = 2073600 dots.

A color depth of 32 bits means that 32 bits = 4 bytes (1 byte = 8 bits) are used to store the color of one pixel (that is, one point on the screen).

Therefore, in order to store information about the color of each point of the screen, it is necessary

2,073,600 x 4 = 8,294,400 bytes of memory.

1 KB = 1024 bytes, therefore 8294400 bytes = 8294400: 1024 = 8100 KB.

Answer: 8100 KB.
