How much time is spent scanning across each row of pixels during screen refresh on a raster system with resolution of 1280 X 1024 and a refresh rate of 60 frames per second?

3 years ago
Computer Graphics

Resolution = 1280 X 1024

That means system contains 1024 scan lines and each scan line contains 128 pixels Refresh rate = 60 frame/sec.

1 frame takes = 1/60 sec = 0.01666 sec.

1 frame buffer consist of 1024 scan lines (It means then 1024 scan lines takes 0.01666 sec) 1

1 scan line takes = 0.01666 /1024 = 10.6 𝜇sec
