Use Projector with Ubuntu 12.04 and Display port

[theunsheydenrych]

HI
I would like to use a projector with my laptop, just like a second screen, when doing presentations.
The projector is linked to the laptop via a mini display port, at the moment the projector is displaying the screen at 640x800, and the refresh rate is not correct.
The laptop screen resolution is 1920x1080, the max resolution for the projector is 1024x768.

The laptop is a Dell XPS L702x with a nvidia screen card, and the projector is a NEC NP3150 Projector.

I would appreciate it very much if someone can help, or direct me, please.

Thank you in advance.

Hello,

Did you ever get your problem resolved?

I'm working on trying to get Ubuntu 12.04 LTS to recognize my Acer C120 projector with no luck. I thought perhaps you may have found something that could help me as well?

Thank you,

Scott
