the 'p' is like the native resolution. i think by 720 you mean 768...
but anyway
there are 2 different types of hi-def... this is a big secret that places like best buy dont want you to know.
there is "768p, 1080i" and "768i, 1080p" basicly the 'p' is the resolution of the tv... in other words, the actual number of pixels the tv has. the 'i' mean that it will convert this resolution to its native resolution. "True Hi-Def" is 1080p.
about half of the hi def channels out there are 1080p the rest are 768p. eventually all will be 1080p. HD-DVD and BlueRay uses 1080p.
I can only recommend buying a 1080p. it is the highest def HD tv you can buy right now. it will recieve 768 signal and convert it up to display on your screen (768i). this is far better than recieving a 1080 signal and converting down to a 768 image
Completely wrong.
There are 5 types of signals you will get from HDTV sources.
SDTV = 480i
HDTV = 1080P > 1080i > 720P > 720i > 480P
Before I explain what i and p mean, a "scanline" is a line of pixels horizontally. For instance, if you have your computer monitor set to 800x600, then it is 800 pixels wide with 600 scanlines.
i means interlaced. Interlaced means that every other scanline of the TV is refreshed at once, then on the next refresh it refreshes the other scan lines. So if the TV has 4 scanlines, on the first refresh it will refresh line 1 and 3, and on the second refresh it will refresh 2 and 4. Standard TV is like this, and it leaves for some nasty looking horizontal flashing lines.
P means progressive scan. Progressive scan means that all the scanlines are refreshed at once. Better picture quality, and no horizontal lines.
So,
1080P means 1080 progressive scanlines.
1080i means 1080 interlaced scanlines.
720p means 720 progressive scanlines.
720i means 720 interlaced scanlines.
480p means 480 progressive scanlines.
480i means 480 interlaced scanlines.
90% of HDTV channels are 1080i.
"P" isn't the number of pixels.
"768P" isn't what he means, he means 720P.
And this is just completely wrong right here, I really have no idea what you're talking about, i has nothing to do with converting anything to anything at all.
there is "768p, 1080i" and "768i, 1080p" basicly the 'p' is the resolution of the tv... in other words, the actual number of pixels the tv has. the 'i' mean that it will convert this resolution to its native resolution. "True Hi-Def" is 1080p.
So basically, just read my post and disregard cwiz's post because there is only one shred of truth to it at all, and that's that "True HD" is 1080P. Oh, and that Blu-Ray = 1080p, but I haven't seen an HD-DVD player that outputs 1080P, just 1080i, so yeah.
