    I have a few wii systems at the house, and have a few CRT televisions. There is next to no information about what I am looking for on the net, so I felt it appropriate to ask here. I have tested a total of 3 wii systems against 2 15khz component & svideo tvs, and notice a difference that is so negligible that for standard definition 240p that I would go so far as to say that there is no difference at all. S-video looks identical to component. I am interested to know how/why this is. Obviously one variable is that the CRT tvs used are consumer grade, and are going on 15+ years old. This in itself is the largest factor. I read but cannot confirm that European models of the wii are not compatible with s-video, but instead have SCART (RGB) connections. There is very little technical information about the S-video coming from the wii, and how it compares to Component at 15khz. Both types are certainly superior to composite, but between the 2 of them, It seems irrelevant at 15khz. I know many systems do look marginally better with Component over svideo, but I am just perplexed by this.

    It's not the console model anymore (as it was for every previous Nintendo home console) but the video region set, for example, with AnyRegionChanger, or Gecko OS and clones including usb loaders
    (which is the cause for the issue popularly known as "ntsc games play in black and red over rgb cables")

    RGB, on paper, is the best (since the GPU outputs digital RGB) - but who knows the implementation of the RVL-AVE and of the monotor itself (mine converts RGB to YPbPr and back, since it's a lot more practical to implement saturation/tint controls on that) and the cable quality!
    And of course, technically superior is what corporations want you to think of, when most people actually don't want Hi-Fi but rather something that's good for them :)

    Early Wiis in particular are claimed to not have stellar YPbPr output: https://assemblergames.com/threads/wii-component-quality-across-console-revisions.53901/

    I am using Official S-video and Component cables, and I am at the point where I believe that the same signal quality is being passed no matter the connection type on 15khz.

    European (PAL) wiis are not compatbile with svideo output but they can have native rgb thru scart. All CRT are native RGB (color crt obviously) so svideo and component will be converted somehow thus loosing a little bit of quality in the process. How much depends on the size and quality of the crt you are using (and also on the quality of the cables). There are a lot of comparison on the net about that. Have a look at this pic:

    There is indeed an improvement from composite (on moving images composite is really crap) but if you have a nice crt with svideo input and good cables does it worth upgrading to a full RGB? It depends on the money you want to spend. I've seen 9'' professional grade crt monitor with only svideo and composite: if I had one of those I wouln't bother going component or RGB (modding the monitor).
