My screen resolution is set to 1920 x 1080 @ 50Hz but when I view the HDMI output on my Panasonic Viera 50", I get a thick black border around the picture. So the desktop does not reach to the edges of the TV. I also don't appear to get any sound through the link and I can't see an option of an additional sound output in the sound settings.
Here are my system details:
Ubuntu 12.04.1 LTS 64bit
Graphics reported by system as VESA RV730
AllSettings > Displays says Panasonic Industry Company 32"
Graphics card ATI Radeon HD 4650
Running ATI/AMD proprietary FGLRX graphics driver
AMD Catalyst Control Centre 2.14 installed
There is a soundcard installed with both Analogue and Digital sound ouputs. I can get that to work
CCC seems to report the TV as being a projector. It does not give me access to any settings that would enable me to stretch the picture or enable underscan/overscan. There are no settings on the TV that would make the picture fit properly.
Also, like I said, I'm not sure how I'm supposed to command the system to output sound through the HDMI connection.
Does anyone else have this Card/OS combo and have got it working successfully. I can post xorg.conf file if required.
