记得四年前在国内的旧货市场里发现过一台二手的14寸JVC专业监视器(450线啊，老板以为是台旧电视，也不知他怎么弄来的)，结果我开价180，他说不行一定得200块。就美滋滋扛回了家。唉，这样美好事情到加拿大就少见了了。

关于水平分辨率，上面有这样的一段文字：

“Since DVD has 720 horizontal pixels (on both NTSC and PAL discs), the horizontal resolution can be calculated by dividing 720 by 1.33 (from the 4:3 aspect ratio) to get 540 lines. On a 1.78 (16:9) display, you get 405 lines. In practice, most DVD players provide about 500 lines instead of 540 because of filtering and low-quality digital-to-analog converters. VHS has about 230 (172 widescreen) lines, broadcast TV has about 330 (248 widescreen), and laserdisc has about 425 (318 widescreen).”

这样看来，DVD的水平解像度也是在500线左右，好像和MiniDv差不多。 <HR></BLOCKQUOTE>

NTSC: 720X480,
PAL 720x576..
