Hello
I have been struggeling to get HDMI output work with to my Samsung LCD TV (Samsung LE40F) without success. I am running Ubuntu 11.4 on an eeebox with Nvidia Ion 2 video chipset. I have installed the proprietary Nvidia drivers and everything seems to work fine, except HDMI. I can connect the TV through VGA and get full 1080 resolution but when connecting through HDMI I get nothing. The LCD TV never picks up the signal.

I have managed to get the nvidia Xserver control panel detect the LCD TV (connected through HDMI while at the same time connecting my LG screen through VGA) but nothing gets picked up by the TV regardless of the different settings Ive tried (and Ive tried every setting you can think of)

I now starting to suspect my Samsung TV does not provide correct edid information but how can I verify this?

Here is a printout from the xorg logfile, does it look like the edid from the Samsung LCD TV is valid?
