Probably not.  One would need to analyze the bits on the (hdmi) wire to
know.  I don't suppose the av unit has any way to display what it sees
on the wire?

BTW, did you post the tv's EDID?  And did you try a simple X11 env, with
just a window manager and w/o gnome or kde or the like?  Maybe something
above X is at fault?
