Many TV that are connected via HDMI through DVI are not capable of
mapping the pixels 1:1. They do some rescaling before displaying the
image on the screen.
See http://pixelmapping.wikispaces.com/Pixel+mapping+explained for more info.

I have seen TV that only showed this problem when connected via
DVI->HDMI, and not via HDMI->HDMI.
