I just switched from a NVidia 9500GT (with nvidia drivers) to a AMD Radeon HD 7750 (with latest catalyst drivers from Vi0L0 repo). I use a Dell U2711 attached to DVI and a Panasonic TX-P50V20E. I just use the Panasonic to watch some videos, so I just activate it when I need it. I think I followed the wiki article about installing the catalyst driver closely and should not have forgotten any step, but maybe I didn't
My problem is I can't get rid of underscan on the TV. There is not even a slider in the ccc. I've already tried turning underscan of with xrandr ("xrandr --output DFP5 --set underscan off"), which just prints the following:
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 141 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputProperty)
Serial number of failed request: 51
Current serial number in output stream: 51
I've also tried setting the variable DigitalHDTVDefaultUnderscan to 0 with aticonfig ("sudo aticonfig --set-pcs-u32=MCIL,DigitalHDTVDefaultUnderscan,0"), that also does nothing after giving me the following output:
No protocol specified
Set key MCIL,DigitalHDTVDefaultUnderscan
I've also tried setting the TVEnableOverscan variable to V0 in /etc/ati/amdpcsdb. After logout and login it is set to V1 again, also DigitalHDTVDefaultUnderscan vanishes.
What else could I try to get rid of underscan?

Run:
amdcccle
So go in tab Screen managment (I use it in italian, I don't know correct translation)>your monitor>regolation, then regulate underscan.

Thanks, but to there is no such thing in the ccc. Here is a screenshot with german UI, but you can see that there is nothing I can adjust:
It sees my tv as projector in linux, under win7 it is correctly recognized as tv with all the options for adjustment.

Is it in digitaler monitor?
if there is not even there, try to read this:

No, "Digitaler Monitor" obviously mean "digital monitor", and that is my Dell U2711.
But still: Thank you! These lines were the ones fixing my problem:
aticonfig --query-dispattrib=tmds2 #to see supported values
aticonfig --set-dispattrib=tmds2,sizeX:1920 # to set X resolution
aticonfig --set-dispattrib=tmds2,sizey:1080 # to set Y resolution
aticonfig --set-dispattrib=tmds2,positionX:0 # to set X position to 0
aticonfig --set-dispattrib=tmds2,positionY:0 # to set Y position to 0
I just needed to change tmds2 to dfp5. Now I will put this into a script for automation and ease of access.
Still it's curios that I need to do it this way and do not have the option to adjust underscan.

Good!
Can you post script for automation? It could be helpful for others with same problem

It's nothing big, just a switch for my special case. If the tv on DFP5 has no resolution set, xrandr will set 1920x1080, then I adjust the size and placement with aticonfig. If the tv has a resolution set xrandr will turn it off. Here's the script:
#!/bin/bash
state=$(xrandr | grep DFP5 | grep +)
echo $state
if [[ ${#state} -gt 0 ]]; then
xrandr --output DFP5 --off
else
xrandr --output DFP5 --below DFP6 --mode 1920x1080 --rate 50
aticonfig --set-dispattrib=dfp5,sizeX:1920
aticonfig --set-dispattrib=dfp5,sizeY:1080
aticonfig --set-dispattrib=dfp5,positionX:0
aticonfig --set-dispattrib=dfp5,positionY:0
