Welcome to the forums :emotion-21:

It's highly unlikely to have anything to do with the monitor.

Before we go on to make any other suggestions, go to the 'Support --> Drivers & Downloads' section for the XPS 420 on the Dell website, and download/install the latest drivers webcam drivers/software available, to see if those make any difference?

Thank you for the reply.  I did download and install the latest Webcam software and drivers, but I'm still experiencing the same problem.

From beginning ....to now ,  I think that sound look like ...may be you don't connect USB cable fron Comp to Monitor?

Yes the USB cable is connected.  As I stated, the webcam works with some features of Webcam Central.  But with WebCam Manager, it reports driver not installed, which, of course, it is.

I bought this monitor only...it's come with a cd software for this monitor (includ web software). Explore cd ...It's has webcam software and I install direct from there...I don't have problem about this....Sorry I can't do any for you.

Thank you for your effort.  Unfortunately, I did try reinstalling the software that came with it, but still the same problem.  I'm disappointed no one from Dell has stepped up with any suggestions.  Browsing through the forums, I see other people are having the same or similar issues.

 Sorry but it's Christmas,  most of us are off including me. I would uninstall all of the webcam software you have on there now, then you need to download and install this driver and this Application. I'm checking on the forums every couple of days so try it and post back.

I am having the exact same issue, I also just received a new Dell XPS 420 with a SP2309W monitor with builtin webcam.  when i try to run the Dell Webcam Manager, I get an error message stating that the webcam driver is not installed. I have tried installing the webcam software from the CD.  I have tried uninstalling and reinstalling from the links Jimmy P provided but I keep getting he same error that "Your webcam driver is not installed.  Please install the driver in order to launch the Webcam Consol."    The USB cable is connected to the computer and to the Monitor.

thanks in advance for your help

Thanks for the reply.

I followed your advice by deleting all existing webcam software, installing the monitor driver you provided, then reinstalling the webcam software you provided.  Prior to my deleting all webcam software, there appeared to be two seperate applications (1) Webcam Central and (2) Webcam Manager.  Now, I only have Webcam Central (which was reinstalled through your supplied link), but I no longer have Webcam Manager.  What is the difference, and do I need Webcam Manager?

i am having the same problem, dell webcam manager (dwm) does not recognize the monitor webcam but it is still accessible through the dell web chat software. my husband is looking into it. he thinks it may have something to do with 32bit applications not seeing 64bit drivers. the monitorcam is recognized by the dwm on our 32bit vista pc but not with the 64bit vista pc.
