Question: Suppose we have a video monitor with a display area measuring 12.8 inches across and 9.6 inches high. If the resolution is 1024 by 768 and the aspect ratio is 1, what is the diameter of each screen point?
Answer: Since the aspect ratio is 1, the diameter can be obtained as:
12.8/1024 = 9.6/768 = 0.0125 inch
