There is an extended section for HDMI after the 128 byte EDID, that occupies the next 128 bytes. 1080p is in there, as well as all the information about your TV's audio (IE surround sound/stereo/etc)

Also quite often every different port of a TV has a different EDID. This is really dumb, but its true. Try reading the EDID from the HDMI port. For a bit of background this is a requirement for analog vs. digital as there is a bit in the EDID that specifies whether the monitor is analog (VGA) or digitial (DVI/HDMI). DVI and HDMI should really be the same though
