1.	Solve : Re: Computer Monitor sizes?
Answer» Why is the sky blue, rateliff. This is a peculiarity of CRT (CATHODE ray tube) monitors. The viewable area is always 1-1/2 inches less than the actual size. Thus, your 20 inch MONITOR comes up a little short when you actually take a RULER to it. LCD monitors don't have this problem. A 15" LCD is EXACTLY 15 inches corner to corner, almost exactly equivalent to a 17" CRT, which is 15.5".
