no output display in projector

hi am having difficulty in display using epson projector. my OS is Win 7 ultimate just trying out and to my surprised it loads on my Latitude D610 unfortunately the video can't be install so a generic driver was automatically installed by windows 7 but the audio was installed using the D610 driver. odd isn't? lol

can someone please help as to how am i able to output the display using the projector. thanks a bunch.
