Difference of 1080p and 1080i
« on: Oct 16, 2009 at 09:22 AM »
i'm having a hard time of choosing the right 32'lcdtv.
i been reading specs of different brand, i only know that 720p/1080p are good in playing movies.
i wonder is the 1080i are same as 1080p?

Maybe what you want to look into in general is the diffence of P and I? Progressive and Interlaced signals? Your panel or source (let's say a dvd player) when even at 480P vs the interlaced signal can make a world of difference ;D

Let me try to explain in laymans term...

Dont be confused with video signal (1080p, 1080i, 720p,  etc) to screen native resolution (1366 x 768, 1920 x 1080, etc).

Some 720p LCD panel (native resolution is 1366 x 768) can accept video signal of 1080p but it is not a FULL HD and it scales 1080p signal in the 1366 x 768 resolution.

While 1080p LCD panel (native resolution is 1920 x 1080), can of course accept FULL HD signal and does not scales 1080p video signal.

There might not have noticeable differences in 32" panel if you are using video signal such as upscaled DVD, or any 1080i and lower resolution sources. But if you are using BD player or a 1080p sources or a PC then even at 32" you will certainly notice the differences.

Also there are many other things to consider in a display panel, the panel itself, the video engine used, other features such as the response time, native contrast, refresh rate... among others.

Note that P (progressive) shows all horizontal scan lines like in 1080P, all 1080 lines are being shown at the same time, while 1080i (Interlace) shows only the alternating scan lines at a given time (1080 / 2 = 540 scan lines; it shows 1, 3, 5, 7, 9 ...... 1079 scan lines for example). Some panel or even source player can compensate missing lines or frames to show better scanning.

The P is always better provided they are in the same number of horizontal scan lines. Again the I only shows alternating scan lines thus the P contains double information compared with I.

Ganyan din yung samsung HTIB ko, walang masyadong difference with different video signal, I just set it to maximum resolution.. after all DVD resolution is only 720 x 480 so even at 480p you are already maximizing the video bit of the DVD. Saka hindi talaga maganda ang upscaling ng Samsung HTIB. So either get Oppo or Toshiba XDE series.

My Extreme upscaling DVD player produces better video quality than my samsung.

You must be comparing the optical and component connections to a 3-jack RCA plug (red and white for audio / yellow for video).

If that's right, the difference is like night and day. Huge, especially for the video.

I prefer the S-video connection rather than the 3RCA cable,

but that's just me sir...

Yes. This is the theory.

In my experience, however, there is little difference between Component and HDMI.

Between S-video and component, I recall that there was not a very big difference but that was a long time ago that I looked at that.

If i remember correctly

Composite and S video - 480p
Component - 1080i ( NMTs claim 1080p)
HDMI- up t0 1080p

This can't be right. No matter what the resolution, interlaced or progressive, the ranking will always be:

1. composite
2. s-video
3. component
4. hdmi

i think agree ako dito.
according to my research component can accept signal of 1080i and 1080p although it is known to be analog.

My post wasn't far different from your post. So I guess resolution output is wrong based on your reply. . From the output resolution I posted , clearly hdmi ranks 1

My ranking would be in order of preference of connection

1. HDMI -1080p
2. Component -1080i/1080p
3. S-video -480p?
4. Composite - 480p - last option

actually no matter what the experts say on such connections,
I still follow what my eye dictates, in my opinion HDMI is at the top of course,
but next to that is the S-video, never did appreciate component nor composite,
but again, that's just me...

I agree

I never really got to see the difference between s video and component during the CRT days but when HDTV came out, I appreciated component connection when I lacked the input for hdmi.

I also prefer 720p over 1080i

Probably because the CRT you tried is not HD-CRT (720p/1080i).  Even for Xbox360 application, 720p can only be activated via Component Video, hence if you use S-Video or Composite Video connection, hanggang original Xbox resolution lang ang kaya.

For the particular reason of having HD-CRTs, I cannot possibly consider an NMT without component video out.  It pairs perfectly great with HD-CRTs via that connection - can actually go up against the 1080p Plasma IQ if size is not considered.  My PC is likewise connected to the HD-CRT via component video.

excactly

I skipped the HD-CRT and went directly to HDTV. CRT tvs have resolutions up to 480p that's why i didn't see any difference.We have a HD-CRT but am too lazy to try out the 1080i output of nmts.

I, however tested the HDMI 720p vs component 720p on a plasma and I found HDMI "slightly" better. I don't mind the 720p component output of a HD source if i had a lack of hdmi inputs

I didn't even know that you can have progressive scan (480p) using composite.  Don't you need at least S video or component for that?  In any case, for smaller TV's its really difficult to differentiate anything above 480p. 

As for audio, rca connections aren't so bad.  The advantage of using optical connections is mainly for viewing movies.  Connecting a DVD player to an amp through optical or coaxial would allow you to enjoy DD/DTS 5.1 surround sound.  Some also use this if the amp processes audio better than the player.  (Better DAC???)

i check out the price of component video cable sa abenson nalula ako nasa 3k+ ang price but the salesman
claims that it is expensive because of its high quality(original).i start to think if this is a practical choice or,
does a good quality RCA cable can compensate for component video cable?
