My Insights

As far as comparing computer resolution to TV resolution, keep in mind that:

Computer monitors usually refresh 75 times a second

TV’s are either interlaced (30 times a second) or progressive (60 times a second)

Regular TV is 480i (640 x 480 interlaced)

EDTV is 480p (640 x 480 progressive)

**Notice that EDTV is NOT-widescreen BUT they sell in widescreen format to compete with HD formats

EDTV widescreen is also 480p (853 x 480 progressive - 60 frames per second)

HDTV is 1080i (1920 x 1080 interlaced)
OR 720p (1280 x 720 progressive)

Old TV’s had a ratio of Width:Height = 4:3
This is also known as FULLSCREEN format

New TV’s have a ratio of Width:Height = 16:9
This is known as WIDESCREEN format

The way you calculate screen resolution is (16/9) * 480 = 853.33 (EDTV widescreen) and so on.

So in short, no, you’re not exactly comparing apples to apples but they’re fairly close enough to compare IF you really wanted to.
