My TV (a DLP) reports a bunch of resolutions in the EDID, but does not 
specify the native resolution (1920x1080) as even an acceptable input 
(probably because the manufacturer didn't think normal Windows users 
could make it work properly).

I definitely agree with this.  Unfortunately, it's set up to make the TV 
work the way the manufacturer expects people to use it--it doesn't 
(necessarily?/usually?/ever?) enumerate all possible configurations.
