Has nothing to do with the signal, it's the design of the TV.
It's a 720p TV which does not show all 1280x720 pixels at once. (I remember reading something on this website about RPTVs and this is the nature of them...)
When you go into HDMI PC mode, to "fit" all the 1280x720 pixels on the screen, the image is actually resized a bit. You can easily tell this if you connect a PC outputting a 1280x720 image and use Wide PC mode. It's mapping is not 1:1
HOWEVER, when you use "Wide TV" with a 1280x720 image, the image is 1:1 but with some slight overscan. The missing pixels don't show up on the projection screen.
As far as the "screen" itself goes, it's more along the lines of showing 1152x648 pixels than 1280x720. (So in wide PC, it resizes the 1280x720 image to 1152x648 and displays it.. in Wide TV, it zooms in on the 1280x720 image and shows 1152x648 of it...)
