You seem to be confusing number of samples with image dimensions.

If you made that much of a change, you must have horribly distorted

Two reasons. First, the mplayer reason, I mostly watch anime and most
anime is 4:3, not 16:9 or whatever other crazy aspects (2.34:1??)
people use for action movies.
Second, and more general.. this is a computer, not a movie viewer.
Presumably you want to use it for writing documents, browsing the web,
composing email, etc. For all of these purposes, it's preferable for
the screen to be tall and narrow. In the old days some people actually
used 3:4 or even 8.5:11 monitors, for this very reason. (And if you're
wondering what the actual rationale is, it's that tracking a long line
of text from the left to the right of a wide monitor is hard on your
eyes.. and tracking to the start of the next line is even harder.
Narrow text, among other things like proper paragraph breaks,
increases readability dramatically.

I was assuming that whichever monitor you chose would have square
pixels, so that the ratio of number of pixels would be identical to
the physical aspect ratio. If this wasn't the case, then all of what I
said was meaningless, sorry.
