Question

Display area of a video monitor measures 12 inches across and 9.6 inches high. If the resolution is 1280 1024 and the aspect ratio is 1, what is the diameter of each screen point?

Answer 1

Answer:

Diameter of point on screen = 0.009375 inches  

Step-by-step explanation:

Data:

Length of monitor = L = 12 inches

Width of monitor = W = 9.6 inches

Resolution of monition = 1280 × 1024

pixels along length = 1280

pixels along width = 1024

Aspect ratio = r = 1

Required:

Diameter of each screen point

Calculation:

we know that

pixel on screen : length on monitor

when aspect ration is 1 then

Considering the Length

1280 pixels = 12 inches

⇒     1 pixel = 12/1280 = 0.009375 inches

Considering the width  

1024 pixels = 9.6 inches

⇒    1 pixel = 9.6/1024 = 0.009375 inches

So

Diameter of point on screen = 0.009375 inches
