Maybe with 'xrandr' ?
Changes primarily depend on hardware. Manual changes in Linux can be done in 'xorg.conf' but don't ask me for details. I don't believe there is much additional playground for RPi, but take a look at elinux.org for special configuration features.

Hi Crashmaster

Thanks for your reply, do you perhaps have the full xrandr command do refresh it ?

Im not familliar with these commands.

Also i followed a article to repair this i could not find the xorg.conf' file - i had to create it.

Let me know

Thanks
