Hmm, that's all the choice that I have I'm afraid:

$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920
VGA-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1920x1080+0+0 (normal left inverted right x axis y
axis) 344mm x 193mm
   1920x1080      60.0*+
   1680x1050      60.0
   1400x1050      60.0
   1280x1024      59.9
   1440x900       59.9
   1280x960       59.9
   1280x854       59.9
   1280x800       59.8
   1280x720       59.9
   1152x768       59.8
   1024x768       59.9
   800x600        59.9
   640x480        59.4
DisplayPort-0 disconnected (normal left inverted right x axis y axis)

Anyway, I'm not the OP and I don't want to hijack the thread ... but
thanks all the same Walter. I didn't know about the xtiming page.
