First of all.
Component cables give you a sharper clearer image, they give you much better color, brightness and sound.
This is ridiculous ... Audio is not part of component standards at all ... on the Wii they are the same as the composite versions of the cables.
I'm suprised nobody even mentioned this... i dont even have an HDTV, I have a Sony wega CRT SDTV and i use component cables and wow what a difference. If you have the Wii, they're the only way to fly. And since you have an HDTV, on top of the better PQ, you of course get progressive scan which is awesome. So you wont get those tiny interlaced squares that you see on interlaced sets, so your image will look crips and detailed, and you'll see games running at full frames.
And more visible aliasing. The difference between interlaced and progressive scan is interlaced does every other line every other frame and alternates between then very quickly, making a less clear image, progressive scan renders much faster and does every line in sequence ... this doesn't change the physical technology in the television just in the method the image on screen is produced. If anything, the artifacts you would notice with interlaced signals would be blank horizontal lines ... not squares. Maybe you're thinking of compression?
Anyways, It's a no brainer, if you dont get component cables you're totaly missing out. And Composite is garbage, and is only good for retro consoles.
Not particularly. If, for instance, you have a game that has very detailed textures, washing them out a bit to get cheap anti-aliasing might not be a bad thing.
Personally i dont know how people play the wii using composite cables, ugh
Component is a must. hell even S-video is a step up.
Not really. The only times you'll notice a difference with S-Video is if things on screen are small, because the improvement is incredibly small. But S-Video is interlaced too. You may notice a difference in colors ... but it'd be quite difficult if you aren't a computer.
By the way those comparrison shots arent that great...you cant really go by screen shots off the net.
Except when you mouseover they show exactly what they're there to show, the difference in sharpness. That's the primary gain when using component cables on the Wii. What the pictures don't convey well because of the small size and choice of games, is the increase in noticeable aliasing artifacts.
