Rumor: Call of Duty 4 only runs at 720p

A blog is running a rumor that Call of Duty 4 only runs at 720p based on one gamer\’s experience. The back of the box claims that it can support up to 1080p but his Samsung Full HDTV can only run the title at 720p. The same person claims that he has tested other full HD games such as Lair and Ninja Gaiden Sigma and they all run fine at 1080p as expected.
