So the way it draws the screen is odd lines, then even lines.. Like old CRT TV sets.<br>p - progressive. It draws the screen progressively, not leaving any alternating gaps between lines. This is newer technology..<br><br>1080 actually is the y-axis resolution (1920x1080).. The normal 4:3 resolution is 640x480..

I don't think there are any broadcasts in 1080p, only 1080i. <br><br>isn't 1080p available for Blu-ray and HDDVD? <br><br><br>I heard that 480SD broadcasts are being eliminated in 2008, and everything here (US) will be broadcast 1080i. Those are the rules, so lets hope they stick to it.<br><br>

I thought it's just the way it's displayed. Just like playing a music CD on a player with a mono speaker, or a stereo Hi-Fi.<br><br>www.waleedsgallery.biz<br>
I think it works like this:<br><br>HD channel broadcasts from my cable provider are 1080i.<br><br>Non HD channels are 480i. That's why they look pixelated when enlarged to fit larger flat panel screens. Your cable box or your TV's setup preferences can change these 4:3 to stupidly stretched or stupidly zoomed (cropped image) to fit 16:9 . I prefer to have gray bars on the side and keep normal proportions to the image.<br><br><br><br><br><br><br><br><br><br>

Interesting to note that the values you give for standard video aren't anywhere near what someone can expect to see on a typical analog TV.<br><br>NTSC actually has a resolution of between 484 - 486 vertical lines (the remaining 39 or so of the 525 scanlines are used for timing of the electron gun and sync). <br><br>Horizontally however, broadcast analog NTSC has a useful limit of roughly 330 lines. But that's for a good high quality set. A cheap set using slower video circuitry might only have 240 lines (note I don't use pixels since NTSC is an analog system and doesn't have a fixed resolution grid). The horizontal resolution of the set is limited to approx. 80 x the MHz of the video circutry. I believe most VCR's use a 3MHz video circuit, so 240 is the limit for VHS.<br><br>Also, about 4:3 to 16:9, a lot of newer sets leave the center portion of the screen unaltered and gradually stretch the sides, making the stretching less objectionable since most of the picture isn't distorted.<br><br><br><br>Hey I'm an F'n Jerk!®

Now here's an interesting article...<br><br>I quote: "Don't take my word for it. How about "Consumer Reports" magazine, the publication of the nonprofit Consumers Union, dedicated to guiding buyers through promotional hype? They do extensive product testing before reporting.<br><br>Here's what they had to say about HD versus ED (enhanced-definition, 480-line) plasma TVs in their March issue: "In our tests of 22 plasma TV models, the best ED set looked just as good with HD content as the HD sets. (One note: Sit closer than eight feet away from an ED set and you're likely to see individual pixels, making the image appear coarse)."<br><br>Read the whole article...<br><br>[color:red]Bibo, ergo sum</font color=red>
