One thing I have noticed when I play my Wii is the fact that I can make my TV change aspects. When displaying my PC, 360, PS2, Xbox, PS3 etc. in widescreen mode my screen won't allow me to change aspects since it's already displaying the minimum aspect in widescreen. I hit the button but the aspect won't change.
It's not the case with the Wii. It seems that the Wii can only do a 4:3 type resolution. To make the picture seem widescreen it squishes more FOV into the picture.
These examples are just samples of what I see. The widescreen image is squished to fit a 4:3 resolution, making things on screen appear thinner. When I hit the aspect button on my TV remote it stretches the image out and fills the screen making everything appear proper. However in doing so I don't gain any extra pixels at all, if anything the pixels are stretched horizontally, making the image appear fuzzy compared to 4:3.
This is a picture in true widescreen. No pixels are distored, every pixel is represented by every pixel in the image data.
Next let's look at what the Wii does with a 16:9 image. It displays the correct FOV except in a 4:3 pixel frame.
Now once I hit the aspect button on my remote it looks like this.
Compare the above to the original picture.
A discerning eye can spot the difference. The picture appears fuzzy because some pixel information bleeds into the next pixel over due to the stretching. Not only that, but it can make the colours and contrast lose their definition as well.
All the Wii does is increase the Field of View, but display it using the same amount of pixels. Not HD. Hell it's not even the 480p they claim.
Try it out the next time you're playing your consoles. Check to see if your TV will allow you to squish your 360 or PS3 and do the same with your Wii.
