You will notice an "eye-popping" difference between composite and HDMI-DVI.

Do you mean component cables or composite cable, 3 cables or one? If component and your tv is well calibrated there won't be a lot of difference.

Huge difference between composite cables and HDMI/DVI. Composite cables don't even support 1080i resolution.

Kayne314 · 03-10-2008, 11:17 PM

Even if you are running component cables right now, the HDMI-DVI cable should improve your image... slightly.

HDMI/DVI is a truly digital cable. It is kind of like lossless audio, but for picture quality.

Component cables take the digital image, divide it into 3 analog signals to pass to the TV, then digitally recombine them into your picture. Most TVs do a very good job doing this, but some are poorer then others.

HDMI/DVI skips the divide and recombine of component cables, and transfers the image in its entirety, untouched. On a nicely calibrated display, you should notice an improvement in sharpness and color.

Depending on the quality of your TV, this difference will range from slight to dramatic. either way, an improvement should be detectable.

Composite cables are just standard definition, and should be avoided altogether.

If you are using component (three cables) for the video and your TV has great processing, you will be hard presssed to tell any difference between it and HDMI.

I have the Sony KV-34XBR800 and I cannot see a difference between component and HDMI to DVI....it has a DVI connector.

That being said......go with the HDMI connection if you have one.

If you are using "composite", you are not getting hi-def.

you've got to go to hdmi, if you can. i never thought that a cable could make such a huge difference, but it does.

Be careful with the terminology...

Composite = F Connector ( Very old style ) BAD Picture

Component = 3ea RCA Connectors ( DVD era ) Good Picture

I thought:

Composite = RCA
F connector = RF

WickyWoo · 03-11-2008, 04:09 PM

Correct. Composite is composite video, 1 RCA plug for video. Component-3 RCA plugs

kalkin84 · 03-11-2008, 04:24 PM

further clarification:

composite: 3 RCA plugs, 1 red (stereo R) 1 white (stereo L) 1 Yellow (picture, allegedly). highest supported resolution is like 376i or something pathetic.

component: 3-5 RCA plugs, 1 red (red color data) 1 blue (blue color data), 1 green (green, gray and stabilizer). also may include a second red (stereo R) and a white (stereo L). Highest supported resolution is 1080p IF the sending and receiving jacks are both HDCP compliant, otherwise 1080i.

HDMI/DVI: 1 multipin connector carries digital video (and audio in HDMI only) and HDCP. highest supported resolution is 1080p. This is the best you can do.

if you're using higher quality cables the audio (red and white) often are not included, i list them merely for reference if you're using the $0.02 courtesy cables most manufacturers include with everything

even if your tv only has DVI, you'll still want to use an HDMI (with DVI adapter) for the best picture. Component will do OK, but not as well. composite... lol.

+1 to what people are saying above.

Composite (Red, white, and yellow cables) isn't HD capable and will force your PS3 into 480i mode.

Component (Red, green and blue cables) is capable of HD but is an analog connection, so your image gets converted to analog and then back to HD which will cause a small (but noticeable) loss in picture quality but will allow your PS3 to display your TV's resolution of 1080i.

DVI/HDMI use the same video signal and it is 100% digital all the way to your TV, which means there's no loss in picture quality or color caused by the cable itself. The picture through this cable is, quite simply, as good as it will ever get.

what about sound? dont know if your using a receiver for the sound but to ensure your getting the best sound this is what i do.
hdmi to receiver and then from receiver to tv
also have component to tv with sound for non surround moments. this way when i watch a movie i can enjoy the sound from blu but non surround times i still get a hd picture
