Resolution is a weird, weird subject. The differences between the lower-end resolutions (ie. 320x240 and 640x480) are quite noticeable at a glance by anybody, but for resolutions above 640x480, it's actually really hard to spot a difference unless you intentionally compare the two side-by-side or you've trained your eyes to spot the difference.
My computer's display is on a monitor which is set to 1920x1200, for example. But at a glance or at a distance, I don't really see any difference between that resolution and the 852x480 my Wii runs at on the exact same monitor. When I look closely, I can of course see the difference quite obviously, but otherwise, not really. I also cannot tell at a glance the difference between S-Video and component video, save that the colors are a bit more vibrant on component.
