I connected my desktop to my HDTV, however, the screen is cut off from all 4 sides unless I set it at a lower resolution. My search-fu seems to be weak today, but I found a couple of threads on intel indicating that putting i915 in the mkinitcpio helps, but I have ATI card and I use xf86-video-ati as the driver.
Here are the screenshots of what I am talking about.
1920x1080 :
EDIT : I just noticed that the screenshot doesn't show the cutoff screen. but on the screen I cannot see the first 3 lines of commands. Also from the left, I cannot see my username in the PS1. From the bottom I cannot see the i3 bar or conky.
my xrandr ouput when I don't have a 10-monitor.conf :
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
DIN disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
DVI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 160mm x 90mm
1920x1080 60.0*+ 30.0 24.0 30.0
1680x1050 60.0
1600x900 60.0
1280x1024 75.0 60.0
1440x900 59.9
1366x768 59.8
1280x800 59.8
1152x864 75.0
1280x720 60.0
1024x768 75.1 70.1 60.0
1440x480 30.0
832x624 74.6
800x600 72.2 75.0 60.3
720x480 59.9
640x480 72.8 75.0 66.7 60.0
720x400 70.1
To get the 1680x1050 resolution, I put this in 10-monitor.conf file under /etc/X11/xorg.conf.d/
Section "Monitor"
Identifier "Monitor0"
EndSection
Section "Device"
Identifier "Device0"
Driver "radeon"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1920x1080"
EndSubSection
EndSection
The resolution is correct, but still the screen is cutoff. So is it possible for me to get the whole screen while in 1920x1080 resolution with the xf86-video-ati driver? Can this be fixed or is this one of those 1080i vs1080p issues where TV resolutions and computer resolutions don't quite match exactly?

Have you gone into your TV's menu to see if any settings affect this? Maybe something like aspect ratio or zoom...

It sounds like TV overscan.
While I prefer the open source version for my purposes, I suspect the catalyst drivers will be much more likely to have settings to compensate for the overscan.
Googling "overscan catalyst" gives many promising looking results, but as I don't have catalyst to test anything out I didn't look further.

I saw this before and it was a TV setting that needed changing. I believe you need to change the TV display to "Normal" rather than "Wide" or "Panoramic" or some such.
Of course verify what resolutions your TV is capable of from its specifications and set your computer to one of those resolutions.
EDIT: Overscan is a possibility, but AFAIK this should only be a problem with CRT screens - not flat screens. Could be wrong though...

Well that helped. My TV Picture was set to 16:9 aspect. Changing it to "Screen Fit" now shows the entire screen correctly. I hope that doesn't screw up the TV viewing..or it will be a pain to keep switching the picture setting. However, the fonts atleast in all GUI apps have kinda become weird. Some letters are randomly darker/bolder than others. It wasn't like this in 1680x1050 res., but that's probably some other issue. Here's what I mean ...

If it's like my TV, it should save settings like that for each input so you don't have to change them every time you switch.

alright. solved it is then... I will try to fix the font issue later...
Thank you all.
