1) Composite Video (Single Yellow cable for Video, White/Red for Audio) is the worse quality. This is because all the colour signals are passed through only one single cable (Yellow).

2) Component Video cables uses three different cables for each colour signals so it is much better Video quality than Composite. Normally the three separate cables are coloured Red, Blue and Green. There must be a component output from your DVD player and a Component Input on your LCD TV in order to use the Component Cable. You must also match the colours from Input to Output in order to get the correct video. (Btw you can also use three different normal Composite cables to function as Component Cables, but make sure they are of good quality).

3) HDMI video is the best quality. It is a single cable used for both digital video signal and sound. (Take note that the signal is Digital as opposed to Composite and Component which are Analog. Digital signal, as long as the cable is decent enough to carry the signal (even a cheap one will do) will output the same quality as a very expensive one. That's the beauty of Digital.

Normally HDMI can not ony be found on Blu-ray players but also  DVD players which can upscale normal DVDs to 720P,1080i, 1080P . These upscale DVD players are of course more expensive than the standard DVD players without upscale function.

I think HDMI is not practical to use now due to its high cost of Blu-Ray discs
and HDMI DVD player.

I will get a component cable which I think is more practical to use for this time being.

Thanks...

So, Composite = RCA, right?

Composite use one single RCA cable for video.

Component uses three different RCA for Video.

Upscale DVD players with HDMI are quite cheap now. The HDMI cables are also quite cheap. No point buying a very expensive cable because the video quality will be exactly the same since it's digital signal.

Component uses three different RCA for Video. You can even use your normal composite cable (Yellow/Red/White) to function as Component cable. Instead of plugging the Red/White cable to the audio, plug them to the Component Video instead. Get another set of cables for your audio if you need it.

Example :- Plug the Yellow cable to the Component Green Input/Output. Plug the Red cable to the Component Red Input/Output. Plug the White cable to the Component Blue Input/Output.

Note, Since it's anolog signal, the better quality cable will give a clearer Video Quality.

I have already said Composite and Component uses Analog signals.

HDMI uses digital signals. All upscale DVD players has HDMI output to carry the upscaled Digital Signal.

Wah... like that ah.? hmm.gif
I do not dare to do this, maybe will get short circuit on my TV... cry.gif
I have to admit that I am a "jungle man" in this area.. laugh.gif

I just get a regular component cable to play safe.

Thank you for your help... notworthy.gif

Please also take note that your LCD TV also has a built-in upscale function. If you do not have an upscale DVD player, the video will only be passed to the TV at 480P resolution through Component Cable and the TV itself will updcale to your TV resolution.

But normally the TV upscale quality is not as good at that from the Upscale DVD player which uses a better chip (depending on which Brand) to upscale to 720P/1080P before passing to the TV.

The component cables they sell are also the same Composite type cables. They only colour it differently so you don't plug wrongly that's all.

Even the LCD shops sometimes use Composite cables to fuction as Component cables.

i never heard of anyone short-circuited their equipment by plug-in the cable wrongly. sweat.gif sweat.gif
just make sure you plug the colour accordingly, otherwise you see the tv colour disoriented.

usually the component cable has a thicker layer of rubber coating to give a better shield against signal interferences.

COMPOSITE<S-VIDEO<COMPONENT<HDMI
usually composite n s-video only being able
to carry Standard Definition (SD) 480p or lower.
but the Component n HDMI can carry av signal up to 1080p.

Finally I bought a component cable for RM 15.00 (1.5 meter long).
Please see attached picture for the component cable that I bought.

I want to tell you guys a joke:
I pulled out the RCA cable, and I installed this new component cable into
my LCD TV's component output and to my DVD player's component input.

I was very excited about to see how good the picture will be after changing
this new component cable on my LCD TV..., all right, after I configured a correct
component detection setting on my LCD TV, all right..., picture came out from
my TV........yeee??? ohmy.gif How come no sound? rclxub.gif

Oh...I was thinking maybe I connected the component cable wrongly, double checked
again, it seemed no problem with the component cable connection setting, yeeee?
Okay, checked the TV setting with my TV remote control, oh.. I did not find any problems
with my TV setting....why still no sound..? doh.gif

Okay, I changed the DVD movie, still no sound...why aah...? doh.gif

Then I turned on my PC and came to this thread again, and I found the answer here...
biggrin.gif , the component cable is for video only, it has no sound. I quickly connected
my RCA (red and white) cable back into my TV, the sound worked.... biggrin.gif
Ha..ha..

Funny ..huh.... biggrin.gif biggrin.gif


Okay, after I have changed my RCA to component, I am not sure if any significant improvement
of the picture quality, unless if I have two TVs side by side with component and RCA respectively,
then probably I can tell the difference.

But I noticed more reddish on the picture when use component cable, so I have to reduce the level
of the picture mode on my LCD TV.

And I noticed my LCD TV is running at 576p, is it good? normal? or bad?


Thanks....

576p mean your DVD player running on pal format, nothing to worry about. And it's on progressive scan mode, good for you, you are maximising the DVD usage now

Oh...Thank you...!!

In Malaysia, are we using PAL format?


Added on November 1, 2008, 4:55 pmIf I want to get a better sound quality from my TV, do I need to buy a better quality audio cable? Or RCA cable (red and white) is good enough?

Thanks...

Yes, Malaysia uses PAL format officially, but NTSC is very common too nowadays. Stereo output is what most TV can do, no need to change that. Unless you are getting home theater system then you might want to shift to sorround sound.

Oh..Thanks..!

I do not have home theater system (I hate the wiring).

My conclusion of this posting:
There is no doubt component is always much better than RCA, since I understand that component is using 3 different thick cables to deliver
Red Green Blue; meanwhile RCA is only using one Yellow thin cable to deliver Red Green Blue. This is no comparison at all in between these 2
cables in terms of delivering good quality picture.

I am glad that I have changed to component cable.

I will use HDMI when Blu Ray discs are cheap... like RM 15.00? biggrin.gif

Thanks again...everybody... notworthy.gif

Either your DVD player is set to PAL mode or it is set to Auto but your DVD disc itself is PAL movie.

Set your DVD player video mode to Auto and try another DVD movie which is in NTSC format.

I set my CMC DVD player in 3 different modes and came out with the following results:

(1) Pal (under progressive) -- 576p
(2) NTSC (under progressive) -- 480p
(3) Multi (under progresive) -- 480p

How do I get 720p?
Do I need to change to a better DVD player to get 720p?
I think my JVC LCD TV can support 720p...

In order to get 1080p, I need a full HD LCD TV and DVD player with HDMI..?
and also need to use Blu-Ray disc? Right?

Thanks

to get 720p, you need dvd player that can upscale the resolution to 720p.
or check the tv setting, whether it can upscale the resolution.

if dvd player with upscaling ability is too expensive, you can try look for 2nd hand old xbox 1 with installed XBMC. XBMC can upscale it to 720p or 1080p.

to get 1080p, you need to make sure your tv support it, if not have to buy new tv.
dvd player with upscaling, or XBMC can give you 1080p, but the quality won't be as good as true 1080p source.

or you might want to do what i'm doing. if your pc graphic card have dvi output, buy a dvi-to-hdmi converter. then you can run 720p or 1080p from your computer to tv. brows.gif

Wah.!!!.. Like that aah....???!!! drool.gif very interesting.... thumbup.gif

To buy a DVI-to-HDMI converter.... icon_idea.gif

In fact, I want to use my LCD TV to connect to my computer to watch movies online.
My computer has a 8X AGP 128MB with DVI output.

I am going to use this solution.... Thank you so much.... notworthy.gif

Like I said before an upscale DVD player will output 720P/1080i (and/or 1080P, depending on player) via HDMI. Standard DVD can only output at 480P via component.

Anyway although your display shows 480P , it just means the input signal from the DVD player is 480P. But like I have also mentioned before, your LCD TV will in fact upscale it to it's own resolution which is 720P. It doesn't show this information though only that the input from your DVD player is 480P.

I have a lot of things to learn in this area.... cry.gif

Last time when I used CRT TV, I just straight plugged in the
RCA cable and watch DVD and VCD only.

Will I get 720p or 1080p if I play normal DVD movies
on a DVD player with HDMI feature? hmm.gif

I will not buy Blu-Ray due to its high price now.

If I do not use Blu-Ray disc, is a DVD player with HDMI necessary for me?
Or a component cable is good enough for playing normal DVD..??

Thanks.. notworthy.gif
