Macbook in HD

Besides frame and scan rates, there are two image sizes that qualify as "high definition." One is 720 lines of 1280 pixels each, and the other is 1080 lines of 1920 pixels each. With 800 lines of 1280 pixels, the MacBook will do the former. With 1200 lines of 1920 pixels each, the Apple Cinema HD display on my Mini will do the latter. The MacBook will scale 1080x1920 to 720x1280 to display it and the Mini will scale 720x1280 to 1080x1920 to display it.
So does that mean if one were to go the HD quicktime gallery and watch a 1080p trailer it would be scaled down and be completely indistinguishable from its 720p counterpart?

I won't say it will be indistinguishable because a critical viewer may be able to tell a difference and favor one way or the other. I will say that the 720 version created by the producer and his equipment is likely to be different from the 720p version created by the MacBook. If you think it's worth the extra download time and processing power to use the 1080 version (i.e. that your MacBook does a better job) rather than the 720 version, go for it. If you don't see a difference, or even think the producer's 720 version looks better on the MacBook, then save yourself some time. Keep in mind this can vary from trailer to trailer.
