HDMI vs DVI vs...
话题: HDMI vs DVI vs VGA vs S-Video vs Component vs RCA
Found some info I've been looking for myself which I thought would be useful to others. Thanks to Adam Holler for the info...(whoever he is).
Number ranking below of preference. 1 being the best.
1) HDMI/DVI (same exact quality)
Both of these connections are identical except that HDMI supports audio. DVI is rectangular and has lots of pins, HDMI is small and trapezoidal. They're literally same. Digital data (basically .BMPs) are carried to your display where they are converted to analog. Literally 0 signal degredation.
Typically uses 5 signal leads. This is the analog connection for monitors. One holds the red data, one the green, one the blue and the other two hold synchronization data in analog format. Is digitized by some types of displays and not by others.
Typically uses 3 signal leads. This looks like a red, green, and blue-colored version of composite. One holds the luminance (total brightness) and a synch, one holds the (red - luminance) data, and one holds the (blue - luminance.) The display uses simple math to determine the missing luminance (which is necessary green data,) and convert the image into RGB (which is what VGA already has.) Note that this only has 1 synch while VGA has 2.
4) S-Video (Y/C)
Typically uses 2 signal leads. S-Video, S-VHS, Y/C, whatever you call it. This is the strange connection a circular head and pins. The highly underrated signal carrier. Uses two leads. One holds the luminance (total brightness,) and the other holds both the (red - luminance) and the (blue - luminance.) I can't remember which line holds the synch, but it doesn't really matter. Y/C is the first on this list which cannot support resolutions other than standard definition (480i/576i.)
Typically uses 1 signal lead. The most common connection for standard definition video. This is the one yellow wire you always get. This carries the luminance (overall brightness,) sync pulses, and color all in one cable. Really terrible, in my opinion.
Typically uses 1 signal lead. Channel 3 or channel 4? This is the sharp, old-school connection your NES probably used and the one you probably still use (though typically in digital mode) for your TV connection assuming you don't have satellite. This smushes sound, luminance, and color information all into one cable and frankly looks absolutely horrible especially since the modulators in the little MadCatz or Pelican R/F adaptors are worthless.

Only VGA worked perfect. HDMI could not do the job.
I hear more people complaining about losing stability when HDMI has to reach to far..

Depending on the quality and diameter of the used HDMI cable, you could say every 15 to 20 meters a repeater is needed.

Not want to talk about the HDMI costs...
I don't have any succesfull expereince with HDMI that's worth the money.
My problem in the future is that almost none of the tv's have VGA anymore.. It's all going to be HDMI or likewise... :(

This varies between devices depending on the converters.
