It could be a connection that is causing this to happen. Go over all your connections that you made to verify all is connected.
To receive assistance from Dell chat support, they need to verify the warranty status and ownership. Then you must troubleshoot with them. Click the "Get Help Now" icon on the right to start a live chat session. If already out of warranty, click here for the Dell out of warranty offering.

Does the screen work in self test mode (hold the D key through powerup to initiate)?
