While I don't support the class action people who bought a 1080p display at a time when *no* displays accepted a 1080p input and got bent out of shape when they realized it only accepted 1080i, I have to say if the manufacturer claims the display is 1080p, but it doesn't properly de-interlace 1080i to 1080p, then you've got a legitimate complaint as far as I'm concerned.
What good is a "1080p" display that is incapable,
under any circumstances, of displaying the 1920 x 1080 pixels in an HD signal?
1920 x 540 is
NOT HD and 1920 x 540 upscaled to 1920 x 1080 is
NOT HD.
Here are Merson's later tests as well:

I was on a rant about this over a year ago an nobody believed me. Anybody believe me now?
It is now SOP for reviewers like CNet (but not Consumer Reports) to verify a display's de-interlacing capability...
