If you are attempting to connect an LCD projector to a laptop,you connect a monitor cable to your video card and the other end to the monitor input connector. You may have to use an adapter, I know on my LCD projector I had to use a DVI to VGA connector.
Can't say much more not knowing if you are having a problem with a particular brand of projector

Did you install the driver correctly?

Before your install the video driver you have downloaded on HP site, first you must un-install the previous driver installed, restart your machine (to clean it up - video driver), boot up your machine then install the video driver.

You must extract the file the you have downloaded from the HP site (make sure to remember the location where it save). Look for the file, run the setup or ".exe" file to install it.
