It could be as simple as this:  Newer LCD screens have higher
resolutions than the older ones, and the aliasing errors on in-between
screen modes, as well as non-synchronised pixels and LCD elements, are
now just smaller.

An 800x600 screen really only works at that rate.  Trying 640x480 on it
is going to look awful because it's not directly half (two graphic
pixels will not cover exactly one LCD element).

Take that up to around twice that resolution, and you've got much
smaller screen pixels to work with.  Errors are much smaller.  And
you've got more options (the native resolution, and direct divisions
like half resolution), ones in-between will still have *some* aliasing
errors.

If OSs would only get better at letting you pick sizes of fonts and GUI
elements, we'd be in a better boat.  Some people don't want to run their
monitors at full resolution as the display gets too tiny, and what they
have to counteract that doesn't do a very good job.
