I can't stop you from posting bad info, but time permitting, I'll do my best to try and make sure you won't mislead unsuspecting members, and hopefully others will as well.
Ok, so basicly you put a ton of effort in not admiting that there are NO ADVANTAGES in an interlaced signal (thanks for the typo fix, english is not my first lenguage.) in a pure technical merit. And you go on and on in pointing out legacy reasons for this instead.
I didn't ask for legacy reasons. I specificly asked you to cite how an interlaced signal is superior to a progressive one but you didn't give me one good example. (mainly, because there isn't one.)
Then you go on to point out how some displays aren't even 720p and in fact have to scale all the time because they're slightly higher res.
I don't even know where you are going with this, but if you were trying to let me know of such fact because you think i didn't know of this for some reason, you're wrong.
Then you talk about how studios don't plan to stop making 480i DVD's...
No kidding!? this must be some sort of breaktrough in deep thought.
DVD's were designed for 480i SDTV's, what a shocker that they'll continue to support what most consumers have in their houses worldwide for decades.
You continue bringing up legacy reasons as to why 480i or 1080i is still alive, but you bring up zero facts as to why it's good for the future of displays. And again, there is not a shred of evidence that display manufacturers plan on continuing to make 1080i native displays ever again.
If that's not enough evidence for you that there's plans to get rid of it, you're welcome to your opinion. But you have to allow me to not be impressed.
Then you go on to say that i'm some how not aware that if i set my PS3 to a specific resolution it would still get scaled by the PS3, because X game isn't 1080p even though my PS3 and set are 1080p...
Ok, you've been assuming what i know and don't know way too much, and i consider it an insult that you keep doing this.
So, for the sake of keeping this civil can you please stop assuming what i know and don't know? It's very annoying.
Because so far you haven't pointed out ONE thing that you've said that is new to me other than i've been misstyping interlaced.
If you own a 720p native display, and you happen to be naive enough to set it to 1080i instead because you think it's higher res. you WILL end up with an uglier output for your games as oposed to just running in a 1:1 pixel ratio. Since the set's scaler will be at work when it could've just been disabled if you used your natives display resolution.
This brings me again to your comment about how some sets don't even have a native HDTV resolution to begin with, and i don't remmember ever claiming otherwise. You can't quote me on this.
For video i don't see this as a big deal, but if i planed on playing games on it i would avoid using such a display if possible. (i personaly would avoid buying one if my goal was gaming.)
Have you ever wondered why some HDTV's are now shipping with a "game mode"? Could it be that it's because scaling is bad for videogames? and now they are doing their best to solve this? let alone the PQ, there's also latency because of scaling. (the only real way to avoid any latency from scaling is if the console or videocard for your PC did all the scaling instead.)
I think it's painfully obvious that if you set your PS3 to 1080p, and your game only supports 720p it's going to get scaled, i again make no mention to make people think otherwise. But you should still set your PS3 to your displays native resolution. (and i'm pretty sure you know this, but since we're playing the "i assume you know jack" game, i'll return the favour.) because of the games that can run at your displays native resolution.
Then you go on to claim that avoiding a scaler won't make things worse, but it can sometimes be better to use the scaler instead of 1:1 ratio?
Ok, i don't know what you're smoking, but can i have some of it?
This comment suggests, that if i own a 720p set, and i got a good enough scaler 1080i would sometimes look better even if my game is 720p only. (this is EXACTLY what you're suggesting here. read what you posted before debating this.) and it's not true. You would actually end up with less visible pixels if you did this, it would be like 540 as oposed to the 720 you could be running. (this is real time 3d i'm reffering to by the way.)
I think it's obvious whats going on here, we both know you know of no reasons why an interlaced signal is better than a progressive one, and you started pointing out legacy reasons instead. There's no debate in legacy reasons.
PC motherboards still keep supporting floppy drives, but this doesn't mean that it's because "sometimes" it's better than using a USB flash drive. It's there for legacy support alone, and it doesn't mean it's there because it's viable technology for the future, it's not. and it will eventually fade out, same thing goes for interlaced signals.
So in the end all you've done is contradict me in why i'm wrong to tell people that it's always better to set your PS3 to your displays native resolution.
I don't know if you REALLY belive this, but if you do. then you're flat out wrong.
And by the way, i'll stick to my story that the only reason 1080i came about is mainly because of early RPTV CRT's. and that the main reason broadcasters use it is legacy reasons belive it or not, because it's not even a bandwidth efficient broadcast method. (and yes, i know that as far as video goes, a 1080i broadcast can get deintercaled and result in a 1080p frame, but guess what the cost of this is? bitrate, which for mpeg2 will end up making things worse and that happens to be the broadcast standard.)
So, i think there's not even a debate as to why a 3d game will always look better if you can get it to run in a 1:1 ratio. (there's not, even though you claimed there is.)
But here's an example of why even for broadcasters 1080i isn't all that sexy compared to a progressive broadcast:

Anyway, we've taken this out off topic to an obscene ammount, if you want to keep "educating" me, i suggest you use a PM from now on.
And if you do decide to PM me, please stop assuming what i know and don't.
I'll make sure i do the same.
