摘自CNET.COM的一段话:50寸以上的尺寸,1080P才能显示出优势
原文如下:
The truth about 1080p
In the last couple of years, there has been a big influx of HDTVs with 1080p native resolution, which typically cost a good deal more than their lower-resolution counterparts. But as we've been saying all along, once you get to high-def, the difference between resolutions becomes much more difficult to appreciate. We've done side-by-side tests between two 46-inch LCD HDTVs, one with 1366x768 resolution and the other with 1080p resolution, using the same 1080i source material, and it was extremely difficult for us to see any difference. It becomes even more difficult at smaller screen sizes or farther seating distances--say, more than 1.5 times the diagonal measurement of the screen. We've reviewed a 37-inch 1080p LCD, for example, where it was impossible to see the separation between horizontal lines at farther than 45 inches away.
Here are a few reviews where we compared 1080p displays directly to lower-resolution models:
Sharp LC-46D62U (46-inch 1080p LCD)
Vizio GV46L HDTV (46-inch 1366x768 LCD)
Westinghouse LvM-47W1 (47-inch 1080p LCD)
Samsung LN-S4096D (40-inch 1080p LCD)
Sony KDL-40XBR2 (40-inch 1080p LCD)
Sharp LC-37D90U (37-inch 1080p LCD)
We're not telling you to ignore 1080p HDTVs. They technically do deliver more detail, which can enhance the viewing experience for more eagle-eyed viewers. Also, many manufacturers build other picture-quality benefits, such as better contrast and/or color, into their 1080p HDTVs simply because those sets are the high-end models. And given the continuing march of technology, we expect more and more 1080p models to become available at lower and lower prices. Today, however, the premium for 1080p is still pretty steep, and unless you're getting a very large set, say 50 inches or more, we don't recommend basing a buying decision on whether or not the television has 1080p native resolution.
大意是这样的:
两台46寸的电视,一台的分辨率是1366X768 一台是1080P(1920X108),播放同样的1080i信号,很难看出区别。如果是在对角线长度1.5倍的距离外,就更难看出了。一台37寸的1080P的电视,在45英寸(1.14米)的距离上,已经看不出水平扫描线。除非你有超强的眼力,否则,我们并不推荐购买低于50寸的1080P电视。
