Question

Информатика: A video game displays images on your monitor having a full HD resolution (1920x1080 pixels). Each pixel contains R, G, B LED s, and each LED is controlled to shine at one of 256 levels. The game produces a new image on the screen 25 times per second. How many megabytes (MB) per second are being sent to your monitor while you are playing your game?​

babohka1 · Answer

1920x1080 = 2073600 pixels in FHD screen

1 led have 256 levels = 1 Byte

1 Pixel have 3 color = 3 * 1 Byte = 3 Byte

1 FHD picture is 2073600 pixels * 3 Byte = 6220800 Byte

If the picture change 25 times per second

6220800 Byte * 25 = 155520000 Byte in second

or

155520000 Byte : 1024 = 151875 Kb in second

or

151875 Kb : 1024 = 148,3 Mb
