I'm trying to get rid of the over-scan on my htpc which is connected (HDMI) to my JVC TV.
So var I'm using: “xrandr --output HDMI-0 --transform 0.95,0,-60,0,0.95,-40,0,0,1
”
but I can't seem to get the screen out of the upper left corner (also tried --pos).

Info:
(The HTPC is running Xubuntu 14.04 and I'm using open-source drivers for my ATI Radeon HD 4600).
xrandr info:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 16mm x 9mm
1920x1080 50.0*+ 60.0 59.9 24.0 24.0
1920x1080i 60.1 50.0 60.0
1280x720 60.0 50.0 59.9
1440x576i 50.1
1440x480i 60.1 60.1
720x576 50.0
720x480 60.0 59.9
640x480 60.0 59.9
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)

Can you post the output of 'xrandr --prop'.

Hello metaschima,

'xrandr --prop' gives me the following info:
