Here it goes

I got a nice LCD (32" ) TV from a good manufacturer. On its manual I found that the native resolution for this display is 780p (great!). I live in Brazil and in this "advanced" nation there are no 1080p TVs for now. The thing is:

1 - On the manufacturer (Philips) site, its written that the TV supports 1080i as an HDTV resolution. Does it mean that you can input this signal and it will be iterated to 780p or what? There is no way this TV can output 1080i on the display, right?

2 - Is there any big difference between 1080i and 780p? Watch for the letters "i" and "p".

3 - All of this comes to an end: I wan to buy me a PS3 in Q1 2007 or Q2 2007. And some say that when you set on the console 780p the image goes down to 480p. This I've seen on several reviews including reliable ones like gamespot.com; users say that you can output 1080p through HDMI but with video component cables its always 480p. My TV has an HDMI cable so you might ask why the rush!? I also have a 350 Watts RMS 5.1 home theater with digital (optical) audio input, being used by a Sony DVD. I don't want to use the HDMI cable for sound (otherwise I'll have to mute the TV), I want to have full 5.1 explosions on my living room. Does anyone know how to make the PS3 run 780p on DVI/Video Component cable or just by the HDMI cable?

I wonder how many views will it takes to get me a single answer...

If the TV is rated at 720p (not sure if you misread or if they have different standards in Brazil, but up here it's 720p and 1080i) then it will downsample 1080 to make it 720, probably a small loss of quality but it should theoretically work fine if the TV is equipped for it (which it may not be).

1080i has greater resolution but is interlaced (which I personally hate) 720p has a lower resolution but is progressive scan (much better IMHO), for a TV of your size 1080 isn't likely to make a noticable difference in quality. I personally would say do not buy 1080i but instead get either 720p or 1080p

HDMI cables are going to be required for essentially anything displaying 1080i/p. From what I understand component is not physically capable of transmitting 1080p but I'm not 100% on that. Additionally component isn't digital while HDMI is, I would say use the HDMI cable and figure out how to hook your TV up to your stereo.

there isnt a big difference from 720p to 1080i.
so you should be good to go.

they make an adapter for that.

component can run 1080i or 720p not sure about 1080p either.
and component is an anolog so it uses the d.a.c. from the source
and then the a.d.c. for the monitor.

the dvi,hdmi just bypasses the d.a.converters and the a.d.converters.

1024x720 vs 1920x1080 is not a big difference?


2073600 pixels

= 1,336,320

A difference of over a million pixels! 8O

You surely don't want to waste your money on a new monitor that doesn't support at least 1080i these days. The only advantage 720p holds over 1080i is in sports tv, in anything else 1080i is superior with its much higher resolution...

Component or VGA are more than capable of displaying 1080p and above, and component is not analog like your standard RCA cables are, there would be almost no difference in picture between component or hdmi/dvi cables

The only reason HD/1080i specifically doesnt work through component is b/c manufactures are making limit it to HDMI, also with new HDCP you might be required to have to use HDMI to watched high def movies in the future

damn i did say that component are anolog

i must have inhaled too much silicon today at work

Damnit icy I cant believe I just made an account to correct your ass...

first off... you cant just compare resolutions...
1080i only shows 540 of those lines at any given time, while 720p displays... wait for it... all 720
and its 1280x720, not 1024x720...
geez people research a little before you post...

so its 1280x720 vs 1920x1080/2

so the pixel difference is much smaller than what you said... secondly... then you get motion aritfacts in 1080i that you dont get in 720p...

So no, there is not much difference between 1080i and 720p...

Nice work on the correction mborucki, and to add to it sirheck you were right too, component is analogue, it is sort of like a compressed version of RGB. Stop spreading misinformation icy.
The reason why you don’t notice a big difference between component and DVI/HDMI on an LCD is because lcds are an analogue display type i.e. the signal must be converted to analogue before it can be displayed. Therefore the only advantage you get from using a digital cable on a LCD is that you move the D to A conversion from your graphics card to the LCD, stopping any EMI that analogue cables may have picked up along the way.
Try DVI/HDMI on a digital device such as a DLP projector and you will get a larger benefit.

i know that is interlaced when it is 1080i, i mis remembered the that it is 1280, regardless 1080i does not show artifacts like you state and monitor that can de-interlace the signal that was in 1080i to p can get the full effect of 1080p.

Regardless of whether only 540 lines are displayed till the next refresh 1080i is still superior than 720p,

like i said earlier 720p is only superior in sports tv

component can be analog or digital...
if you were to generalize then i guess you component is analog.

i'll make note of the added benefit of hdmi/dvi on DLPs

you are right in a way, as you can send either a component or an RGB signal over a DVI/HDMI connection but i think what the OP was referring to was component connections as in the red, green and blue RCA type cables.

Well, thank you all for answering. I guess Ima try the component video first then. If it doesnt work then I'll have to buy me a HDMI cable and mute the TV. As for the resolution, 720p (sorry for typing 780p, its finals on my college you know!?) would be great for the PS3. Waiting for a good 1080p HDTV wont make my eyes bleed from what I've seen here. They should be cheaper in a couple of years by now and the rest of the money that I would spend I can save it for the PS4 lol.

Why does all Toms Forumz end up in fights!? Geez chill out guys, its just a god dam question
