My jaws dropped when I found this out accidentally. I just couldn't believe my eyes. I have been watching VCD/DVD for years, only to realize now that every time when I watch a VCD/DVD, I only see about 85% of the actual area! I'm reasonably knowledgeable with home theater system, but this completely knock me out. I have a 4:3 CRT TV, 27 inch Sony Wega to be exact. Last week I played a DVD video source with 4:3 aspect ratio on my computer, then play it on TV again from DVD player. All of a sudden I noticed that I can see more from computer than from TV. Basically, on every side (top, bottom, left, right), the computer shows about 4% more than the TV, which is a quite big margin. In other words, the width on TV is trimmed by 2 times the 4%, or roughly 8%, the height is also trimmed by roughly 8%. The total visible area on TV is only 92% x 92% = 85% of the actual area, compared to what you can see from computer! (I'm talking about the relative area here, not the absolute area. Of course the TV screen is much larger than computer screen). At first I thought it might be related to TV/DVD settings, but no matter what kind of display settings I use, I got the same thing. I have two DVD players, and they do the same thing. I asked some of my friends to compare this difference between computer and TV, and they found the same thing too. It's best to see this phenomenon with a video source of 4:3 aspect ratio, either VCD or DVD will do. You may also see this with Letterbox DVD, but it may be less obvious. I saw this phenomenon on 4:3 aspect ratio TV, but I'm not sure about HDTV, maybe HDTV won't have this kind of thing. Please try this and see if you see the same thing as my friends and I do. Any computer software will do, such as Windows Media Player, or Cyberlink PowerDVD. Please shed some light if you know anything about this. I'm really confused. Thanks!
