xrandr adding a new monitor resolution

[bitodd]

hi, i am trying to create a new monitor resolution using xrandr (for my plasma), following these instructions -http://solutionz.yolasite.com/linux/add ... buntu-9-10

but when i try to --addmode it does not work, if i type xrandr again i can see it in the list but cant select it in control panel - monitors

could someone please tell me where i am going wrong

found my problem. added "default" after --addline, and now i can see it control centre/monitors.
problem now is, i find in small print at the bottom of the manual that the resolution is only for the 50" and mine is 42"
