projector

I have an Acer Aspire 8951G running 12.04 Pangolin with bumblebee working beautifully.

My problem is that when I connect either the VGA port or the HDMI to my projector there is no way I can see to properly set up the resolutions or colours. The default basic display driver sees the projector correctly, but messes up colours and resolutions (on hdmi) and resolutions on VGA. (Its a 1280 X 720 projector)

Am I missing some sort of Xorg configuration? nvidia-xconfig does not seem to exist and running optirun nvidia-settings -c :8 opens the settings, but of course only for the one display. I just want a way to set a default config for my projector via VGA or preferably HDMI. Any help would be wonderful.

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
