What the heck is "True HD" anyway?

[DeadlyNinja]

I keep hearing that 1080p is "true" HD, but if that's so, then what is 720p? Is 720p HD or not?

 

[RobertR1]

It's a marketing term to get you to cycle out your current HDTV.

I suggest wikipedia.org to you, deadly ninja san

Oh noes! My 720p is unworthy! I must rush out and drop another $5k on a new TV. I must, I must.

But.. what if I can support 1080p input.. but it downscales to 720p output?

That's completely retarded, why would a 720P set accept a 1080P signal?
Makes no sense considering there is only one 1080P source (bluray, not sure if hd-dvd has 1080P output yet.)
More likely is a "1080P" set not accepting a 1080p signal.

Can I have your old one?

k thx bye

A little supersampling for console games with retarded resolution options?
Not a big market segment in any case, but you know, more obscure things have been implemented in search for product differentiation.

YES! Your HDTV is actually False HD.

what about 576i on my 7" black and white TV? it's gotta be HD given the sharpness and fine details

That's what is technically called Vintage HD.

That's what is technically called Vintage HD.

So.. what is SD then?

 

[Geo]

480i, max. I believe VHS is 240i tho. Well, I guess 480p (most DVD players at this point) is also SD.

... It was a joke...

I thought VHS was 240p.

(seriously, forget about Vintage HD) 480p is what used to be referred to as ED (enhanced definition). SD is 480i or the European 576i (or whatever the number is).

HD starts of at 720p and ends at 1080p.

320x200 ftw!

I'm pretty sure I'd rather have a sharp game then a slightly blurry one with a bit less aliasing.
Besides that will never happen anyway, for the consoles lifespan there will always be 720P for 1080i output options which every HD can take. (ignoring the crts that cant take 720P.. sony.)

That's just silly. On a 720p TV, a downsampled 1080p (free AA) picture will always look more pleasant than a straight 720p picture with no AA. It wouldn't be "blurry" (losing detail), it would look cleaner than the 720p image. Let's not confuse SSAA for "blur filters".

Cheap scaler= blur filter

 

[London Geezer]

Cheap scaler= blur filter

... If you say so... Any chip that can be called a scaler will show a better 720p when there's some free AA on it (as it's downsampled from 1080p which has double the pixel count), then a straight 720p picture with no AA.
