Overscanning on TrimSlice

[crazystick]

Hi all,

Just got Arch installed on my new TrimSlice, and connected to TV (32inch 720p) via the HDMI port. The borders of the screen are missing (they were also missing in the default Ubuntu install) and from a bit of searching, I see that I should be able to correct this with xrandr but I get the following:

$this->bbcode_second_pass_code('', '
$ xrandr -q
Screen 0: minimum 256 x 128, current 1280 x 720, maximum 2048 x 2048
LVDS-1 disconnected (normal left inverted right x axis y axis)
HDMI-1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1280x720 60.0*+
$xrandr --output HDMI-1 --set underscan on
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 148 (RANDR)
Minor opcode of failed request: 11 (RRQueryOutputProperty)
Serial number of failed request: 27
Current serial number in output stream: 27
')

I haven't really had to configure an X server for several years, I'm thinking I have to customize the xorg.conf to add some modelines, but I just wanted to check if anyone has already solved this problem and can give me some quick pointers?

Thanks, Paul.
