Late 08 MBP- What is the screen capable of?

[scottintosh]

Hello, I know that the resolution is 1440x900.. but what is that compared to a TV. Like 1080p/i or 720p/i?

900p

Number = vertical resolution
Letter = Interlaced or progressive

1080p = 1920x1080
720p = 1280x720


And for good measure....

1440p = 2560x1440
2k = 2048x1080
4k = 4096x2160

nvm

900p

Number = vertical resolution (did you mean horizontal (width) resolution?)
Letter = Interlaced or progressive

1080p = 1920x1080
720p = 1280x720


And for good measure....

1440p = 2560x1440
2k = 2048x1080
4k = 4096x2160

cool, thanks.. just out of curiosity, is there a formula to determine the first number from the second number... for example.. it its Nx1080, does N have to equal 2048?

No, vertical. There are 900 pixels in each vertical column, and 1440 columns wide.

As for the res, that has to do with aspect ratio. If the display is 16:10 (1.6:1), that means the res is always a 1.6:1 width to height ratio: 1440x900, 1680x1050, 1920x1200, 2560x1600, etc. HDTVs are somewhat wider, at 16:9 (aka 1.78:1), so........1280x720, 1366x768, 1920x1200, 2560x1440, and so on and so forth. 2k digital cinema is its own thing. There are other aspect ratios too, like 1.33:1 for old television and movies, and then there are film ARs, like 1.85:1, or "scope" (2.35:1).

It should actually be 810p. Because 810p is 1440x810. 900p would be 1600x900

ok, cool..

good info to know, thank you!
