Interesting. I've got 14.04 installed. It appears the issue I'm having
may be slightly different. Through our Denon receiver it does not open
up the HDMI connection, however connected directly to the TV it does.
I normally have an NVidia GT220 connected, and know that the Denon
passes along it's own EDID, and I've captured the TV's EDID and "force
fed" it to the NVidia driver to get it to work "best".

I'm now wondering if the issue is I need to take this captured EDID
bin and figure out how to "force" the Intel driver to use it and
ignore the EDID the Denon passes along?

In case anyone has done such a thing and can supply some help? thanks!
