Sharp Aquos will not recognize NVIDIA ION LE Output

http://askubuntu.com – I recently installed 12.04 on my Acer Aspire Revo R1600. Before I installed Ubuntu 12.04, I used the Revo as a multi-media station outputting movies to my 60" Sharp Aquos via HDMI. On Windows XP this worked splendidly. Once I installed Ubuntu, the Sharp no longer recognized the output signal. I am sorely disappointed about this as that is the main reason I use this computer. I can't imagine all of you brilliant folks out there can't figure this out so I have confidence that I won't have to install another distro. Thanks in advance for any assistance you can give me.
