Ok this is an extension of another problem I had with a VGA connection and an Nvidia Geforce GT 440 card. The question has been updated to include other problems related to HDMI Video and also since I have confirmed that it also affects ATI video cards. The explanation is the following:

I have a Soneview 32' TV. This TV has many connections including VGA (First reason I bought it), HDMI (Second reason but did not have a HDMI cable at that time) and DVI.

I have had this TV for little over a month now, actually I had it to celebrate the release of Ubuntu 11.10 and started using it exactly on that date (I know too much fan there but hey, I like geek stuff). I started using it with the VGA cable. After 2 weeks I bought an Nvidia GT440 card. The previous 9500GT which was using the VGA connection was working correctly with no problems whatsoever.

I installed the GT440 and the first problem that I encountered using this latest card is mentioned here: Black screen on latest Nvidia/Ati Cards when starting LightDM/Ubuntu. The solution to this problem was to actually disconnect then connect again the VGA cable. This would result in the screen showing me the lightdm screen for my login. If I did not disconnect then connect the cable I could be there forever thinking that there is no video signal. The black screen problem was solved in a later update for 12.04 and already solved using the default 12.10. So using 12.04 and updating or using 12.10 solved the black screen with HDMI problem.

I got tired of looking for answers that did not work and for solutions that made me literally have to install Ubuntu again. I just went and bought an HDMI cable and changed the VGA one for that one. It worked and I did not have to disconnect/connect the cable but now I have this problem when using any resolution. My normal resolution is 1920x1080 (This TV is 1080HD) so in VGA I could use this resolution with no problem, but on HDMI am getting the borders cut out. Here is a pic:

As you can see from the image, the Launcher icons only show less than 50% of their width. Forget about the top and bottom parts, I can access them with the mouse but I can not visualize them in the screen. It is like it's outside of the TVs view. Basically there is like 20 to 30 pixels gone from all sides.

I searched around and came to running `xrand --verbose`

to see what it could detect from the TV. I got this:

```

If it helps, the Refresh Rate at 1920x1080 is 60. There is a flickering effect at this resolution using HDMI but not VGA which I imagine is related to the borders cut off issue am asking here.
