What do the numbers and junk mail (480i 480p 720i 720p 1080i 1080p) be a sign of when you buy a high-def tv?
Answers: Standard television is 480i.
480 lines of information contained by a screen.
"i" method interlace: the TV makes 2 pass down the screen to draw the logo. This is what causes those "scan line" you see.
For High Def - they created 3 more resolutions of signals:
480p ("p" mechanism progressive like your computer monitor)
720 p/i
1080 p/i
Most exchange cards channels use 720. It took a while for TV's to be capable of display 1080, and now HD-DVD and BlueRay are the merely good sources of 1080, but more will come. You should buy a TV that handle 1080p
IMPORTANT:
HD televisions must adopt all the numbers. But respectively television have a internal or display resolution. Make sure you read the fine print and get a TV that have 1080 internal resolution, not one that simply 'accepts' 1080.
My HDTV is 3 years old and is a local 720 unit. If I nurture it 1080, the TV down-converts the signal to 720. If I feed it 480, the TV up-converts the signal to 720.
those numbers refer to the max resolution of the small screen.
1080p is currently the best resolution in open market standards right now. The sophisticated the number the higher the resolution and the better the picture feature.
