Sounds like you have an unlucky display.  Even without an EDID, your
TV will likely work with the standard HTDV timing modelines (it should
for devices like cable boxes and DVD/BD players).  Also note that some
tv's automatically overscan HDMI for some reason, you may have to
adjust the TV itself to remove that.
