I would like to see s-vid vs component, rgb scart vs component or s-vid...



this is still cool though :)

I did a dreamcast vga vs composite screen thing with soul calibur and it was nuts!

Check out gamesx.com

They do a really good breakdown of RGB vs everything else.

You'll be converted if you aren't already.

Yeah, I know, but still it's nice to see it for myself and maybe the few others who aren't using it yet.

How did you get RGB out of your SNES?

If we put an rgb lead, a scart lead, a set of composite cables, a set of svideo cables, a set of component cables and an RF switch into an octagon UFC style, who'd come out alive?

Ok here is basically the jist of it:
RF pros:
?
RF cons:
Everything

Composite pros:
It lets you see the image
Composite AV cons:
Colour Bleed (affects colour images)
Dot Crawl (affects colour images)
"Rainbow" (affects B+W images)

S-Video pros:
Image is crisp on most colours and there is no rainbow effect on B and W pictures
S-Video cons:
Colour Bleed (seems to mainly affect red)

Component VS RGB:
Component:
Think as this of S-Video but without colour bleed
RGB:
Brighter colours, contrast and sharpness than component.

Boredom strikes again, so I made a few pics concerning RGB and Composite, been done before of course, but I wanted to see for myself what the results are.

I would also like to add that the quality of composite and S-video is basically dpeendant upon the qusality of the sending and recieving equipment. Therefor technically you can't say that S-Video isn't much of an improvement over composite; because on some equipment it bages one big difference

I can second that. My S-Video is way better then my composite on one tv, but not much of a difference on another.

I weep for the lack of RGB support in the States. RGB monitors are so damned expensive here, not to mention that finding one is almost impossible.

S-video is ok, composite is passable, RF is a sin (but it still gets the job done).

Component and RGB should be virtually indistinguishable. The difference you see probably comes from your source device generating RGB internally and then converting it to component. If you were using a DVD player, HDTV receiver, or Gamecube, using component would look better(because their native format is YUV).

Is this a trick question? :oh_no:

You take the little cover off the AV port around the back of the snes,plug in the rgb cable,put the other end into the back of your tv and then put in a game and turn it on?


All snes' (apart from those little ugly snes2's)output RGB straight from out of the box.

The Native format of the console doesn't matter though because the native format of the TV is still RGB, so in the end the conversion from YUV to RGB still has to take place SOMEWHERE; whether that be in the console, or in the TV.

Also I would like to add to that the conversion from YUV to RGB is ususally done digitally when inside the console, therefore there will be no difference between the RGB and YUV if it is converted using a processor then converted to analogue.

No, it wasn't a trick question. I didn't know they sold Component cables for SNES, my bad.

That is true, but they should still be indistinguishable. The difference between RGB and component is only in format really, not quality. There is a simple math formula to convert between the 2, but I can't remember it right now. And technically, RGB is considered a form of component video (RGB instead of Y,Pb,Pr).

I'd like to see both pictures of component and rgb right next to each other to PROVE whether or not the signal qualities are indistinguishable or not.

They don't,only RGB scart cables.You need a tv that either has a scart socket or one that has the seperate r,g,b and sync lines.

RGB is the purest signal whereas component is digitally manipulated to get the same picture quality.Side by side there is virtually no difference.

As the US cube doesnt have rgb capabilities(and there is no way I would be settled for playing games in crappy s-vhs fuzz-o-vision™),over her we need a component cable that has the ends cut off and wired into a scart plug along with the AV lead(to carry the sync line to compose the picture and l/r sound).Also the end that plugs into the back of the cube needs a small mod with one of the legs on one of the chips lifting and taking to another point on the board(with resistor).

I do have a pal cube as well so I will try and take some pics to see if anyone can tell the difference between a pal cube with true rgb output and an ntsc cube with component/rgb output.

Both standards use 3 wires for picture information, but component mixes the sync info into each of the 3 picture wires, whereas RGB uses a separate sync wire(some forms of RGB can have the sync mixed into the green wire).

Here's some more info http://www.proav.de/video/RGB_YPrPb.html

Component was designed to save bandwidth used by raw RGB by using more processing power compared to RGB.

To those worried about quality of component, just remember that it is the standard connection for HDTV, up to 1920x1080, so the lowly 320x224 that Neogeo uses doesn't even scratch the surface.

I don't really get any screen artefacts on my S-VHS connection
The only problems I get are a slight colour bleed on red.
